what is food chain? explain it by giving examples
Answers
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. Food chains are the basic unit of any ecosystem, connecting with one another to form the food webs that map the interactions of life on Earth. Life on Earth is a big deal. Read up!
Food Chains on Land
Land-based food chains represent the most familiar forms of nature to humans. 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. One fascinating break in that pattern is the omnipresent decomposer. Organisms ranging from bacteria and maggots to the noble cockroach feed on the dead, and in doing so break them down into the nutrients that keep the food chain going. By eating and excreting, decomposers return the nutrients of dead organisms to the soil, which nourishes the plants that start the chains all over again.
