Natural Selection; Natural selection<span> is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.</span>
True.
Nitrogen-fixing bacteria converts atmospheric nitrogen into forms which plants can readily use. These microorganisms are essential in the nitrogen cycle. Nitrogen in the atmosphere is known to be inert or non-reactive. The nitrogen fixation process breaks the triple bond between the nitrogen making it usable in other processes.
Similar types of rocks in places, same species of animals with slight different evolutions to adapt to climate, the landmasses actually look like they fit together, etc..
The role of species in an ecosystem, consisting of such things as what it eats, when it eats, and where it lives is niche.
