Question #1: Three examples of biotic factors in an ecosystem is 1. A fox eats a rabbit, fox gets food and rabbit population stays the same. 2. A coyote eats a squirrel, coyote gets food and squirrel population stays the same. 3. A duck eats a mosquito, duck gets food and mosquito population stays the same.

Question #2: Fish, deer, and beavers. Fish fit in by providing food for the deer and beavers. The deer help by leveling out the populations of fish. The beaver build dams and level out fish population. The trophic levels of these three organisms are the deer at the top, then the beaver, and at the bottom the fish.

Question #3: Phytoplankton (producers) ->

Zooplankton (consumers) ->

Crustacean (consumers) ->

Fish (omnivores) ->

Squid (omnivores)->

Seal (carnivores)->

Killer Whale (omnivores)->
