Question

Quizplus · Accepted Answer

The process of photosynthesis by green plants and phytoplankton produces oxygen, which is an abiotic factor that improves the quality of the environment for many organisms.

Option A is incorrect as it describes the impact of a predator on species diversity, which is a biotic factor, not an abiotic factor.

Option C is also incorrect as it involves the interaction between animals and plants, which is a biotic factor.

Option D is incorrect as the presence of dams is a human-driven activity, not a natural process, and it does not directly impact the abiotic environment.
