Question

1. what level of organization includes both biotic and abiotic factors?

○ population
○ ecosystem
○ tissue
○ community

Explanation:

• A population is a group of the same species, so it only includes biotic factors (living organisms of one species), not abiotic.
• An ecosystem is defined as a community of living organisms (biotic factors) interacting with their physical environment (abiotic factors like water, soil, sunlight).
• A tissue is a group of cells in an organism, which is a biological structure within an organism and does not involve abiotic factors or multiple species/communities.
• A community is a group of different species living together, so it only includes biotic factors (various living organisms), not abiotic.

So the level of organization that includes both biotic and abiotic factors is an ecosystem.

Answer:

B. Ecosystem
