Explanation:

1. An ecosystem is a community of living organisms (biotic factors) interacting with their non - living environment (abiotic factors) in a defined area. Option a only considers the physical environment, option b only plants and animals, and option c only living organisms interacting with each other, so option d is correct.
2. A biome is a large geographical area characterized by specific climatic conditions and distinctive plant and animal communities. Option a refers to species interactions, option b to a single organism, and option d to species number, so option c is correct.
3. Ecosystems play many crucial functions, including pollution control. They can filter pollutants, absorb carbon dioxide, etc. Habitat destruction, energy pollution, and resource depletion are negative impacts rather than functions of ecosystems, so option b is correct.

Answer:

1. d. Ecosystems consist of biotic and abiotic factors that interact within a defined area
2. c. A large geographical area with specific climatic conditions
3. b. Pollution control
