Question

which is an example of an abiotic factor that could impact the diversity of an ecosystem?

the introduction of an invasive species can change the amount of available resources in an ecosystem.

an increase in acid rain could change the ph level in an ecosystem.

an increase in prey can impact the number of predators in an ecosystem.

the competition for the food can the survival rate impact the survival rate between same species.

Explanation:

Abiotic factors are non - living components of an ecosystem. The introduction of an invasive species (first option) involves a living organism, so it's a biotic factor. An increase in acid rain (second option) is a non - living factor as acid rain is a chemical and physical phenomenon. An increase in prey (third option) and competition for food (fourth option) involve living organisms and their interactions, so they are biotic factors. So the option about acid rain changing the pH level is an example of an abiotic factor impacting ecosystem diversity.

Answer:

B. An increase in acid rain could change the pH level in an ecosystem.
