Question

Which of the following is an example of a man-made ecosystem?

• A. Herbarium
• B. Aquarium
• C. Tissue culture
• D. Forest

Answer 1

Answer: (B)

Herbarium and tissue culture are not examples of the ecosystems. The forest is a natural ecosystem. Aquarium is an example of an artificial or man-made ecosystem. Hence, biodiversity and nutrient cycling will be less in an aquarium as compared to natural ecosystems. The decreased biodiversity will ultimately result in low productivity of the ecosystem. Also, such an ecosystem will not be a stable ecosystem.

Thus, the correct answer is option B.
