Which of the following levels of ecological organization has only biotic factors?

• ecosystem

• community

• biome

• biosphere

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.
