Larry's food web
The trophic level of an organism is the position it occupies in a food chain. The word trophic derives from the Greek referring to food or feeding. A food chain represents a succession of organisms that eat another organism and are, in turn, eaten themselves. The number of steps an organism is from the start of the chain is a measure of its trophic level. Food chains start at trophic level 1 with primary producers such as plants, move to herbivores at level 2,predators at level 3 and typically finish with carnivores or apex predators at level 4 or 5. The path along the chain can form either a one-way flow or a food "web". Ecological communities with higher biodiversity form more complex trophic paths.
humans impacting on earth
-humans help the plants, and we help fertilizer the earth ground.
- we help keep the community clean by picking up the trash.
- we don't help the earth by not polluting the right way.
- we don't look in to the population of the animals in the world today so we might be killing the last species.
