What is the herbivore in the following food chain: algae → fish → herons?
decomposers.
Algae feed small fish which starts the food chain.
food chain in pond: Algae -->Protozoa-->Small Fish --> Big fish
Algae are microscopic organisms that grows in the water. Algae is eaten by fish or krill and other tiny creatures. In a food chain it would be considered a producer because it harnesses the sun's energy to create food that is consumed by other organisms.
Algae form the main basis of the aquatic food chain.

fish eat algae and bigger fish like sharks eat the fish
This is an example of a food chain, specifically showing the transfer of energy in an aquatic ecosystem. The algae is the producer, the small fish is the primary consumer, and the large fish is the secondary consumer. This sequence demonstrates how energy flows from one organism to another within a food chain.
