Food chains & food webs
The term food chain refers to the sequence of events in an ecosystem, where one organism eats another and then is eaten by another organism. It starts with the primary source like the sun or hydrothermal vents where producers make food, continues with consumers or animals who eat the food, and ends with the top predator. A food chain is a sequence of events in nature in which one organism eats another, and is then eaten by another in turn. All food chains start with the primary source, either the sun or chemicals produced by hydrothermal vents deep in the ocean. When an organism uses those sources to make food, it starts the food chain. The process continues to the organisms that eat that plant or animal, then the organism that eats what ate it, all the way to the apex predator , an organism that eats others but is not eaten itself. Here, we have brought together a collection of examples of food chains for you to study.
The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whale s—needs food to survive. Each food chain is a possible pathway that energy and nutrient s can follow through the ecosystem. For example, grass produces its own food from sunlight. A rabbit eats the grass.
Within the food chain energy can be passed and transferred from one organism to another. Whilst mammals get their energy sources from food — whether this be eating other animals or eating vegetation; plants get their energy from photosynthesis. Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers. They are then eaten by tertiary consumers and in a long food day these can be eaten by quaternary consumers. Each stage of a food chain is called a trophic level.
