<span>When listing the components of a forest ecosystems, a scientist would list all the plants, animals and microorganisms, as well as all the non-living elements that combine to make up the entire ecology of the forest. </span>
<span>a and c could be true
Animals don't have peace treaties with each other and the other two options would both allow a population to increase in size.</span>
Answer:
A. It allows two populations to evolve separately.
Explanation:
Geographic isolation is theorized to have catalyzed the formation of new species. Let’s say groups A and B of a bird species get separated by something, and they can’t cross between to interbreed or exchange alleles.
We describe this as no gene flow, which is the opposite of choices C and D. Because of this, they may diverge if given enough time due to the difference in environmental pressures, because they’re now in different environments.
B is incorrect because it doesn’t apply.
