Text Solution

Verified by Experts

Living organisms depend on each other for their food requirement and form a food chain. Among the various ecosystems, each one is having definite food chain.
`rarr` The trophic inter-relationship between animals in nature cannot be explained as simple chains only.
`rarr` The length and complexity of food chains vary greatly.
`rarr` Each organism is generally eaten by two or more other kinds of organisms which in turn are eaten by several other organisms.
So, instead of a straight-line food chain, the relationship can be shown as a series of branching lines called a food web.
