Question

a creek provides habitat and breeding sites for several different amphibian species. which scale of life represents the interactions between the amphibians (living organisms) and the creek (nonliving/abiotic)?

population

ecosystem

community

biome

Explanation:

1. Analyze each option:

• Population: A group of the same species. It doesn't include abiotic factors like the creek, so this is incorrect.
• Ecosystem: Consists of all living (biotic) organisms and non - living (abiotic) components in an area and their interactions. The amphibians (biotic) and the creek (abiotic) interacting fit this definition.
• Community: All the different populations in an area, only biotic factors, so no abiotic (creek) included, incorrect.
• Biome: A large area with similar climate, vegetation, etc. It's a broader scale and not about the interaction of local biotic and abiotic factors here, incorrect.

Answer:

B. ecosystem
