Food webs are different than food chains because a food web is an area of the residents/ organisms living in an area. Example:
The forest of Connecticut has a food web of all of the below in the order they go in; Decomposers: Mushrooms, fungi, bacteria. Producers: Plants, trees etc. Consumers: Mice, Squirrels, birds. Secondary consumers: Snakes, Owls. Primary consumers that eat the secondary consumers: Wolfs, Coyotes, vaulters. Scavengers: they eat the remains of the carcass of the Primary consumers. Then the food web starts over, unlike a Food chain that shows all of the animals in one country or state that shows every step and gets way too complicated and misses some important details. Hope this helps :D
I think its D. but I'm not sure The reason being is it's a prosses that doesn't require the "help" or "cooperation" of other cells and it only effects the one cell.
