Choose the biotic factors that characterize the deciduous forest biome.
a. deer, maple trees, lichen
b. moderate rainfall, cool and warm seasons
c. african elephants, giraffes, grass
d. very wet, poor soil

The answer should be A) The word "deciduous" alludes to a tree that sheds its leaves regularly, and these backwoods are overwhelmed by such trees, and walnut, among others. Among the mixed bags of creature life are deer, timber wolves, deer and wild bears. Including so many other creatures.

Biotic factors are the living things that determine an ecosystem. So by knowing that, we can eliminate B and D. And between A and C, A is correct. Deciduous forest biomes can be found in the eastrn half of United States, and I'm positive that you have never heard elephants and giraffes being native to US. And the only place to see those animals are in zoos where they are shipped from their homeland. So, once again, the answer is A.
