The dynamics of an ecosystem depends on two main processes:

Question

Quizplus · Accepted Answer

The dynamics of an ecosystem is primarily driven by two main processes, which are the unidirectional flow of energy from one trophic level to another and the cycling of nutrients through the ecosystem. Energy flows in one direction only, from the sun to the producers to the consumers, and eventually to the decomposers, while nutrients are cycled through the ecosystem, moving from the biotic to the abiotic components and back again. Therefore, the best answer is B, which correctly identifies the unidirectional flow of energy and the cycling of nutrients as the two main processes that drive ecosystem dynamics.
