Food chains & food webs

A food chain is a linear network of links in a food web starting from producer organisms such as grass or trees which use radiation from the Sun to make their food and ending at apex predator species like grizzly bears or killer whales , detritivores like earthworms or woodlice , or decomposer species such as fungi or bacteria. A food chain also shows how the organisms are related with each other by the food they eat. Each level of a food chain represents a different trophic level. A food chain differs from a food web, because the complex network of different animals ' feeding relations are aggregated and the chain only follows a direct, linear pathway of one animal at a time. Natural interconnections between food chains make it a food web. A common metric used to the quantify food web trophic structure is food chain length. In its simplest form, the length of a chain is the number of links between a trophic consumer and the base of the web.

The table describes some common terms used to describe living things in their environment:. A food chain shows the different species of an organism in an ecosystem , and what eats what. A food chain always starts with a producer , an organism that makes food. This is usually a green plant, because plants can make their own food by photosynthesis. A food chain ends with a consumer , an animal that eats a plant or another animal. Here is an example of a simple food chain:.

Actually this is a misconception. We use all of our brain. For example, if you had 10 glasses of water, one glass of water would represent 10 percent, or one-tenth. It would look like this! Here is an example :.

Ecology and Environment is an important topic from the point of view of competitive exams. Here in the article, we have covered all the functions of Ecosystems in detail. The ecosystem is said to be the structural and functional unit of Biosphere. It includes all living beings interacting and influencing each other and the environment surrounding them. The functional factors of the ecosystem keep the components running together.

Green plants make their own food. They use the energy from the sun to make their own food. Some of this food is used, and some is stored in the roots, stems, and leaves.
