Vegetal stratification of an ecosystem influence

Question

How does the vegetal stratification of an ecosystem influence the biological diversity?

Answer 1

The vegetal stratification of an ecosystem, like the strata of the Amazon Rainforest, creates vertical layers with peculiar abiotic and biotic factors, dividing the ecosystem into several different environments. Thus, in the superior layer near crowns of big trees, the exposition to light, rain and wind is greater however moisture is lower comparing to inferior layers. As one goes down the strata, the penetration of light reduces and moisture rises.

Concerning the biotic factors, communities of each and every stratum present composition, food habits, features, and reproduction strategies, and so forth, also different. These variations in the biotic and abiotic factors make the selective pressure on the living beings as well diversified, there are more ecological niches to be explored and more differed beings appear throughout the evolutionary process.
