Consider statements about ecology: 1. An ecosystem includes living and non-living components. 2. A community includes only one species. 3. A population includes individuals of the same species. Which are correct? MCQ with Answer and Explanation

An ecosystem is a functional unit comprising both the biotic (living organisms) and abiotic (non-living physical environment like soil, water, sunlight) components interacting as a system. A population is a group of individuals of the same species living in a specific area and interbreeding. A community consists of all the interacting populations of different species living together in a defined area, not just one species. Thus, statements 1 and 3 are correct.
