Question

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

Answer 1

Hint: In an ecosystem, primary consumers are the herbivores that feed on the producers, and the secondary consumers are the organisms that depend on primary consumers for their food. Tertiary consumers are the organisms that feed on both the primary and secondary consumers for food.

Complete answer: A pond ecosystem is a system of different organisms living together in a pond or a lake. It is a biological system that includes water and plant and animal life interacting with each other in a closed community of organisms in an enclosed body of water.
Producers in a pond ecosystem are phytoplanktons and aquatic plants, and the primary consumers are zooplanktons that feed on the producers. The secondary consumers are small aquatic animals that depend on primary consumers for their food. Tertiary consumers are insects, larvae, fish, bird, etc. that feed on both the primary and secondary consumers for food. The food chain of a pond ecosystem can be depicted as Phytoplanktons and aquatic plants → Small aquatic animals → (insects, larvae etc.)→ Fish → Bird.
So, the correct answer is option B.

Note: There are different types of pond ecosystems, including salt pond ecosystems, garden pond ecosystems, underground ecosystems, freshwater pool ecosystems and vernal pool ecosystems. Different characteristics that mark a pond ecosystems apart from other ecosystems are still water, surrounded by banks, wetness and humidity, different levels of habitat and variability in size.
