Question

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

Answer 1

Ans-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.

Biotic factors including plants, animals, fungi, algae and bacteria and abiotic factors includes sunlight, temperature, moisture, wind or water currents, soil type and nutrient availability.

Therefore in the superior layer near the crowns of big trees the exposition to light, rain and wind is greater but moisture is lower compared to the inferior layers ( both are affected by abiotic and biotic factors). As one goes down the strata the penetration of light diminishes and moisture increases.

Both biotic and abiotic factors are related to each other in an ecosystem, if one factors is changed or removed, it can affect the entire ecosystem. Regarding the biotic factors, communities of each stratum presenting differ composition and features, food habits, reproduction strategies, etc. Such variations in the abiotic and biotic factors directly affect how organism survived,there are more ecological niches to be explored and more varied beings emerge during the evolutionary process
