Food Chains

What is a Food chain Activity?

A food chain is A series of organisms in which each organism depends for food on the one before it. The flow of energy and nutrients through an ecosystem represents the flow of energy and nutrients. In a food chain The first organism in The chain is always a producer which is an organism that can create its own food through photosynthesis or chemosynthesis. Producers are generally plants but some bacteria and algal species can also function as Producers.

Primary consumers are The organisms that eat plants. Primary consumers then are ate by secondary consumers which are carnivores that eat other animals. Tertiary consumers are the top of the food chain and eat secondary consumers. At every stage in the chain energy is lost as heat and only about 10 of the energy from one level is transferred to the next level.

Food chain is important as it helps to maintain the balance of an ecosystem. The results show how different organisms are connected and dependent on each other. When an organism is removed from a food chain it can have ripple effects on the entire ecosystem. For example if a predator is removed from the top of the food chain the population of prey may increase which can then lead to a decrease in the populations of the prey’s food source. Knowledge of the food chain can help us to better protect and preserve the delicate balance of our ecosystems.
