Answer:
1. Environment is the surroundings and conditions in which organisms live and modify throughout time.
2. Ecology relates to the biological study of organisms and how they react to other organisms and their surroundings.
3. The atmosphere (air), lithosphere (land), and hydrosphere (water).
4. Herbivores are killed by carnivores, thus stopping overgrazing and proceeding to feed the carnivores. And because carnivores are at a higher trophic level than herbivores, and there are therefore fewer carnivores, the ecosystem stays in balance.
5. Directly or indirectly, all animals in an ecosystem rely on plants to create and store energy to continue growing, and (since they are at the bottom of the energy pyramid), feed the next level of the pyramid, thus continuing the life circle of the ecosystem.
6. It is a hierarchal organization of organisms that is dependent on each member to continue to maintenance of the ecosystem. Ex: grass -> rabbit -> fox -> mountain lion -> bear -> fungi
7. An ecosystem is a community of animate and inanimate things which survive and thrive off of one another. Man can negatively influence or ruin ecosystems by creating problems such as interfering with ecosystems (via deforestation, etc) or pollution (via mass production, landfills, etc).
8. We can protect the natural environment by cutting back on what we take from it, therefore cutting down on things like plastic and paper, replanting crucial parts of ecosystems that we use like trees, and treasuring what we are using like reusable products.
