Question

Explain your observations on what organisms need to grow. Also discuss ways in which human activity can impact an organism’s ability to obtain the resources it needs to survive. Share your opinion about how human activity can be changed to have less impact on the lives of other organisms.

Answer 1

"No man is an island.” This saying is also true for organisms in an ecosystem. No organism exists in isolation.  Individual organisms live together in an ecosystem and depend on one another.  In fact, they have many different types of interactions with each other, and many of these interactions are critical for their survival.

So what do these interactions look like in an ecosystem? One category of interactions describes the different ways organisms obtain their food and energy. Some organisms can make their own food, and other organisms have to get their food by eating other organisms. An organism that must obtain their nutrients by eating (consuming) other organisms is called a consumer, or a heterotroph. While there are a lot of fancy words related to the sciences, one of the great things is that many of them are based on Latin or Greek roots. For example, heterotroph becomes easier to remember when you realize that in Greek, “hetero” means “other” and “troph” means food; in other words, heterotrophs eat other organisms to get their food. They then use the energy and materials in that food to grow, reproduce and carry out all of their life activities. All animals, all fungi, and some kinds of bacteria are heterotrophs and consumers.

Answer 2

Organisms need each other to grow

Explanation:

All living organisms need the assistance of each other to survive in the environment, which can be seen in the food chain of ecosystem. All living organism has the ability to acquire the resources for their growth and has a particular mechanism to do so. But human activities have certain negative impacts on the environment and on organisms.

Some of these factors that affects environment are- excessive population that leads to harming of ecosystem for human needs, pollution is an important one which accelerates extinction of numerous species etc. If we need to save the environment then we should take steps to reduce pollution first by using eco-friendly materials.
