A food chain always starts with a producer.Did you know producers make it’s own food?For example a plant or a Plankton is a producer.Now my friends let me tell you what a consumer is?A consumer is something that eats producers for example a consumer is a bee,cow or krills.A decomposer is something that feeds on meet like a killer whale is a decomposer and so is a leopard seal.
And now the moment that you have all been waiting for ,we will give you a example of a food chain.Now the krill eats the algae then the fish eats the krill and finally the penguin eats the fish ,hope you understand.
