Multiple Choice
At the ecosystem level of ecological organization, which of the following best describes the relationship between biotic and abiotic factors?
Biotic factors, like animals and plants, exist independently of abiotic factors such as water and temperature.
Abiotic factors, like sunlight and soil, directly affect how biotic factors, such as plants and animals, survive and interact.
Biotic and abiotic factors are completely separate and do not influence each other in an ecosystem.
Only biotic factors are important for the functioning of an ecosystem, while abiotic factors are irrelevant.
