Select the narrowest level of organization that includes abiotic factors.?

Question

Select the narrowest level of organization that includes abiotic factors.

I am debating between community and ecosystem

community

population

biome

ecosystem

Answer 1

Population--> group of same organisms able to reproduce

Community--> sum of all biotic factors; group of populations interacting to each other(predation, mutualism, etc)

Ecosystem--> biotic + abiotic factors

Biome--> ecosystems with the same conditions/climate(decidous forest, grassland, etc)

so ecosystem is the answer.

Answer 2

A community includes only organisms - not abiotic factors.
