For example, green plants, phytoplankton and algae are some examples of producers in a food chain. State an example of such organism which can multiply by this process. Food webs are never straight.
Consumers are all organisms that are dependent on plants or other organisms for food. *the flow of energy from one species to another at various biotic levels forms a food chain. Everything ultimately derives its energy from the sun, and most food chains follow the pattern herbivore, carnivore, maybe another carnivore or two, apex predator.but there is an almost endless diversity within that pattern and even a few chains that break it.
Teacher taught students about the energy flow by drawing a food chain. Each level in the food chain is called a trophic level. Sol:food chains are the relationships between organism living in an ecosystem.
