Answer:
Biotic factors (that is, things that are living) depend on abiotic factors in an ecosystem.
Step-by-step explanation:
Biotic factors are everything in an ecosystem that's alive. This includes animals, plants, bacteria, et cetera.
Abiotic factors are everything in an ecosystem that's passive and nonliving. This includes air, sun, weather conditions, rocks, et cetera.
Biotic factors are dependent on abiotic factors. For example, plants (biotic) need light (abiotic) to photosynthesize, and some animals (biotic) consume the plants, continuing the cycle in the ecosystem.
