Answer: (A)

Verified step by step guidance

1. Understand the definitions of the terms provided: A 'Population' refers to a group of individuals of the same species living in a specific area. A 'Community' refers to an assemblage of different populations (multiple species) living together in a defined area. An 'Ecosystem' includes the community of organisms along with the abiotic (non-living) factors in the environment. A 'Biome' is a larger classification that includes ecosystems with similar climates and organisms.
2. Identify the key phrase in the question: 'an assemblage of different populations that live together in a defined area.' This indicates that the focus is on multiple populations (different species) coexisting in the same area.
3. Eliminate incorrect options: 'Population' can be ruled out because it refers to individuals of the same species, not different populations. 'Ecosystem' includes abiotic factors, which are not mentioned in the question. 'Biome' is too broad and refers to a collection of ecosystems, not just populations.
4. Match the definition of 'Community' to the question: A community specifically refers to different populations living together in a defined area, which aligns with the description in the question.
5. Conclude that the correct term is 'Community' based on the process of elimination and matching the definition to the question's description.
