Question

What are the components of the common food chain of a pond ecosystem?

• A. Phytoplanktons, zooplanktons, aquatic plants, small aquatic animals
• B. Phytoplanktons, zooplanktons, aquatic plants, small aquatic animals, small fishes, big fishes, birds
• C. Phytoplanktons, zooplanktons
• D. None of the above

Answer 1

The correct option is B Phytoplanktons, zooplanktons, aquatic plants, small aquatic animals, small fishes, big fishes, birds

In pond ecosystem, the food chain starts with primary producers i.e., phytoplanktons that prepare food by photosynthesis process which is consumed by the primary consumer i.e., zooplanktons or small herbivores such as tadpoles, snails, small fish. Secondary consumers derive food from primary consumer e.g., medium sized fish, frogs. Tertiary consumers are the organisms which can feed on the primary and the secondary consumer, e.g., duck and crane. Predators include the big fish, hawk, and humans.

Thus, the correct answer is option B.
