One or More Possible Roles Plants Could Play in the Future of Humanity? How are These Roles Different Than What Occurred in the Past?

Plants are very, and I mean very, important to humanity. As humans we consume plants, and we also use plants for things other than consumption. Since plants are so very important, what are one or more roles plants could play in the future of humanity? How are these roles different from what occurred in the past?

There are thousands of plant species, and most of these plants have not yet been explored when it comes to use. Who knows, maybe in the future we will discover new species of plants which are nutritious, sustainable to grow, etc, which can be used for food, or other various reasons. Also who knows maybe in the future we will find plants which can be replacements for other plants which are not very sustainable to grow. 

How are these roles of plants different from what occurred in the past? Plants especially the ones that us humans consume are quite a bit different than how they were before. Now with the rise of chemicals being used on plants, and the scientific modification of plants. Also plants today have a far wider range of uses than before, which is due to the technological advancement today.


How does photosynthesis affect the transfer of energy through an ecosystem? I was asked to consider the forms of energy that are readily available, and processes that make this energy available to other organisms in my answer. Well this seems confusing enough; to make it more simple I have created a scenario for explanation purposes.

In the beginning a seed grows into a plant, which in turn spreads more seeds. Also a herbivore most likely when passing by these plants will consume these plants. The herbivore uses the plant to get fuel and nutrients to continue on the day. The waste of these herbivores will go back to the soil which in turn will provide more nutrients for new plants. Maybe this certain herbivore is killed and eaten by a carnivore. Which in turn provides nutrients to the carnivore.

Now with this analogy in mind, photosynthesis helps transfer the energy from the sun to plants; these plants are most likely food for some herbivores. The Herbivores are food for the carnivores. Which in turn is how photosynthesis affects the transfer of energy through an ecosystem.


Many Biologists are passionately fascinated by prokaryotes, the way a “normal,” person might be excited by sports, music, or any other hobby. What are some of the characteristics that get scientists so excited about these tiny, primitive creatures? How do I feel about them?

Some of the characteristics of prokaryotes that biologists may get excited over include: some prokaryotes are harmful to humans or can kill you, and others are beneficial and are necessary for your survival. Also prokaryotes are very small, around eight micrometers long, and live with limited organelles. Prokaryotes are the most studied cells by biologists, and these characteristics that I mentioned above interest biologists.

To conclude, how do I feel about prokaryotes? To me prokaryotes only interest me due to school; personally I do not become excited about learning more about their characteristics, unlike a biologist. 

What Would Happen if More Hawks Entered a Community

In a community with five trophic levels: plants, crickets, mice, snakes, and hawks, what would happen if more hawks entered the community through immigration? What is my reasoning for the outcome? 

Because hawks are predators, that will mean that the population of prey will decrease. Also because snakes are predators too, now there will be an increase in competition between predators. Because of the competition between predators the population of snakes may decrease. With less prey, meaning less food for the hawks, the hawks may emigrate or leave that area to a location with more prey. 

The population of crickets on the other hand in my opinion will stay pretty much the same. Of course they will still be preyed upon but I believe that will not affect the population that much. The plant population will most likely remain the same also.

Tropical Rain Forest vs. Tropical Dry Forest

A biome is a collection of plant and animal species that have common characteristics from the environment that they live in. There are many biomes in this world; two of these biomes are: tropical rain forest and a tropical dry forest.

A tropical rain forest is somewhat similar to a dry tropical forest since they are both tropical but they are definitely different. A tropical rain forest is very wet and humid; on average a tropical rain forest has 200-400 centimeters of rain yearly. The tropical dry forest on the other hand is dryer, with 150-200 centimeters of rain yearly, which is still a fair bit of rain.

The tropical rain forest and tropical dry forest are two unique biomes that have different yet similar characteristics.


When you hear the word cancer you probably think of a terrible disease, which is very complicated and unknown, which is understandable. Common questions that people ask about cancer include: is it alive? Why aren’t Doctors able to find a single cure for it? Is It contagious? 

The answer to the first question: is cancer alive? The answer to this is a little complicated because cancer is caused from cell mutations or cells that no longer do what they were designed to do. These mutated cells act out in the body like a virus, and are dependent on the body, which generally means that cancer is not alive.

Cancer is complex; there are many types of cancer. Cancer is a very broad term to describe a series of diseases. Because of this doctors have not been able to find a cure. Of course there are treatments for cancer, a common example of which is chemo. 

But is cancer contagious? No. Cancer is not contagious, not in the way like a cold or any other contagious illness. This is because cancer is not alive, like I pointed out above. But you can inherit cancer through genetics, but I would say that this is not the same as being contagious.

In conclusion, cancer is not alive, incurable due to how many types of cancers there are, and not contagious.

Why Men are Far More Likely to be Colorblind Than Women?

Males have an X and a Y Chromosome, a female on the other hand has two X chromosomes. Color Blindness is an X linked trait, which makes it seen that women are far more likely to be colorblind, but statistically men are far more likely to be colorblind than women. Why is this the case?

Like I mentioned above color blindness is an X linked trait, but another thing about color blindness is the fact that it is a recessive gene, which means if a woman was to be color blind she must inherit this gene from both her mother and father. Women also can pass down the gene to her children. Men as I stated above statistically are far more likely to be colorblind, this is because they don’t have an extra X chromosome to cancel out the gene, which in turn means that if they inherit the color blind gene they most definitely will be color blind.

Hence, because females have X chromosomes, the only way for a woman to be colorblind is if both her parents have the colorblind gene. But because men don’t have an extra X chromosome if they inherit the gene they most definitely will colorblind.

Why Does Your Heart Beats Quickly When Surprised/Startled

When someone sneaks up behind you and shouts “Boo!” For a little bit your heart beats faster, even though you didn’t do any physical activity that would of course increase your heart beat. But what caused your heart to behave this way after being startled or surprised?

When I am startled my body becomes aware of a potential threat, or something that may potentially be dangerous for me. When my body is aware of this it releases certain chemicals and hormones which will put my body into the mode of “fight or flight.” The unique phenomena of “fight or flight,” heightens my senses, and is my body’s response on how to react to potential danger, by either “fighting,” or “running.”

In short, this is why your heart beats quickly when you are surprised/startled.

Why do Living Creatures Have Such a Difficult Time Obtaining Energy

As most know all living things need some sort of energy to survive; and most also know that the sun provides a tremendous amount(much more than what is used), of energy to earth. But even with all of this available energy why do living creatures still have such a difficult time obtaining energy, and why do creatures still starve?

Well first of all I am not expert in this and this essay is only based on what I think is the answer(s) for the questions above. Also to note not all living things receive direct energy from the sun, for example a lot of living things actually get energy from other living things. So with those things on the clear here is the reason why I think living creatures have such a hard time obtaining energy, why living creatures still starve.

The reason I believe is the fact that in some areas there is a lack of wild plants(which are the primary producers). This is due to a variety of factors, including changes of climate, etc. Because of the lack of plants or primary producers the herbivores(primary consumers), will starve because they depend on plants for their energy. Because the primary consumers are starving off the secondary consumers or the carnivores will now have a shortage of their food or energy source. Hence why living creatures have such a difficult time obtaining energy.

Three Engineering Fields That Interest Me

In this week’s science essay I will be writing about three engineering fields that interest me. These fields are: Biomedical engineering, Chemical engineering, and Systems Engineering. I personally don’t want to become an engineer, but these three engineering fields I found very interesting.

Biomedical Engineering

Biomedical engineering is a type of engineering that applies to the human body. Usually Biomedical engineering is applied to the human body either as a medical or a beneficial way. This field of engineering uses engineering principles to Biology, or in other words the human body. Biomedical engineering is a good College course to take if you want to become a doctor; it is also a good field if you are very interested in Biology.

Chemical Engineering

Chemical engineering is a type of engineering that creates chemicals, raw materials, living cells, energy, etc, into useful items. This type of engineering uses engineering principles of chemistry, physics, mathematics, biology, and even economics. This type of engineering is great if you like high level science such as chemistry and physics, along with math and economics.

Systems Engineering

 Systems engineering is a type of engineering that focuses on how to design, integrate, and manage complex systems. This type of engineering requires math, economics, and even computer science. This type of engineering is great if you like computer science and economics.


These are three engineering fields that interest me.
