Question

Define the term' food chain 'and ' food web '.​

Answer 1

Answer:

A food chain is a series of organisms where all the organisms are dependent on next organism as a source of food.

A network of interconnecting food chains in a natural community of different organisms is called a food web

➦A food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism. The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain. The food chain also explains the feeding pattern or relationship between living organisms. Trophic level refers to the sequential stages in a food chain, starting with producers at the bottom, followed by primary, secondary and tertiary consumers. Every level in a food chain is known as a trophic level.

➦A food web is made up of several interlinked food chains. A food web is comparable to a food chain, except that a food web is far broader than a food chain. A single organism is occasionally consumed by a large number of predators, or it consumes multiple other creatures. As a result, numerous trophic levels become interlinked, and the food chain fails to properly display the flow of energy. The food web becomes more complex when there are more cross interactions across different food chains. A more complex food chain leads to a more long-term ecology.

Snakes can eat mice herbivores and frogs carnivores, while jackals can eat both carnivores and scavengers.

We know that, the levels and positions exist in food webs. Plants are the initial trophic level (level 1)

followed by herbivores (level 2

and finally carnivores (level 3)

The trophic level is one higher than the chain length, or the number of connections that connect to the base. The food chain's starting point (primary producers or detritivores) is set to 0 Energy flow is depicted in food webs via trophic connections. The directed flow of energy contrasts with the cyclic flow of material across food web systems.
