Question

ecosystem examples
which of the following levels of biological organization is correctly matched with an example?
multiple choice

a coral reef with various fish and seagrasses - population

a herd of llamas - community

a lobster - organ system

trees and fungi in a forest - organism

a tropical rain forest with rain, sunlight, trees, insects,
and animals - ecosystem

Explanation:

1. Analyze "a coral reef with various fish and seagrasses - population": A population is a group of the same species. A coral reef with different species (fish, seagrasses) is a community or ecosystem, not a population. So this is incorrect.
2. Analyze "a herd of llamas - community": A community includes different species. A herd of llamas is a population (same species), not a community. So this is incorrect.
3. Analyze "a lobster - organ system": A lobster is an organism, not an organ system. An organ system is a group of organs working together in an organism. So this is incorrect.
4. Analyze "trees and fungi in a forest - organism": Trees and fungi are different species, so together they are part of a community, not an organism (which is a single living entity). So this is incorrect.
5. Analyze "a tropical rain forest with rain, sunlight, trees, insects, and animals - ecosystem": An ecosystem includes all living (biotic: trees, insects, animals) and non - living (abiotic: rain, sunlight) components in a particular area. This matches the definition of an ecosystem.

Answer:

a tropical rain forest with rain, sunlight, trees, insects, and animals - ecosystem
