Some populations may decline‚ and some explode. Humans are usually at the top of the chain and are often responsible for disrupting food webs. All living things depend

called food. Food contains energy. The food (or energy) can be transferred from one organism to the other through food chains. The starting point of a food chain is a category of organisms called producers. Producers are‚ in fact‚ plants. So‚ we can say that all the food chains begin with a green plant (or grass) which is the original source of all food. Let us take an example to understand the meaning of food chain.

FOOD CHAINS and FOOD WEBS There are two types of feeding relationships: autotrophic and heterotrophic. Autotrophic organisms make their own food by the process of photosynthesis e.g. plants. Heterotrophic organisms cannot make their own food (i.e. cannot carry out photosynthesis)‚ therefore must eat other organisms to get their nutrients e.g. animals. A food chain is the feeding relationship among organisms or the series of living organisms that eat each other. A food chain shows the transfer

FOOD CHAINS‚ FOOD WEBS AND ECOLOGICAL PYRAMIDS In an ecosystem‚ plants capture the sun’s energy and use it to convert inorganic compounds into energy-rich organic compounds. This process of using the sun’s energy to convert minerals (such as magnesium or nitrogen) in the soil into green leaves‚ or carrots‚ or strawberries‚ is called photosynthesis. Photosynthesis is only the beginning of a chain of energy conversions. There are many types of animals that will eat the products of the photosynthesis
