Question

Explain the "FOOD CHAIN "

Answer 1

The ultimate source of this energy is the sun. Producers like green plants trap solar energy and convert it into the chemical energy of food. When a primary consumer eats the producer, a part of this energy is passed on to it.The primary consumer is then eaten by a secondary consumer. And the secondary consumer may be eaten by a tertiary consumer, and so on. In this way energy gets transferred from one consumer to the next higher level of consumer. A series of organisms through which food energy flows in an ecosystem is called a food chain. It may also be defined as follows.

Food chain :

• It is the flow of energy from one organism to the next and so on.
• It usually starts with producer and ends with a carnivore.
• In a food chain, an organism gets food from one group of animal.
• Let's taken example : Grass➜Insects➜Frogs➜Snakes.
• Here, grass is producer, insects are primary consumer,frog is secondary consumer and the snake is tertiary consumer.
• When a group of several food chains interconnect, it forms food web.
• In a food web, an organism gets food from more than one group of organisms.
• Sun is the only source of energy for the flow of energy for maintaining the ecosystem on the earth.
• The flow of energy takes place through different trophic levels.
