What are the two major components of an ecosystem?

• Tissues and organs

• Molecules and atoms

• Organisms and cells

• Biotic and abiotic factors

Which of the following is an abiotic factor?

• Water

What is an example of a biotic factor in an ecosystem?

• Grass

• Water

• The climate

• The environment

What does a population in biology refer to?

• All organisms in an ecosystem

• A group of different species

• All living and non-living things

• A group of the same species

Which level of organization focuses on the interactions between different species?
