Detailed explanation-1: -In a pond, green algae are the primary producers. Green algae are consumed by mosquito larvae, which therefore become the primary consumers . Mosquito larvae are consumed by fish, which then become the secondary consumers.

Detailed explanation-2: -One example of a pond food chain would begin with the plants in the pond being eaten by small herbivores, and the small herbivores then being consumed by larger carnivores. As this occurs, the energy gained by one link in the food chain is passed on to the next organism in the chain.

Detailed explanation-3: -At the base of the food chain lie the primary producers. The primary producers are autotrophs and are most often photosynthetic organisms such as plants, algae, or cyanobacteria. The organisms that eat the primary producers are called primary consumers.

Detailed explanation-4: -Green algae and cyanobacteria are found at the beginning of the food chain. They are known as primary producers because they make their own food.

Detailed explanation-5: -Algae
