Question

difference between food chain and food web

Answer 1

Food Chain

The series of organisms of an ecosystem through which the food and energy present in it and  passes with each member is called food chain. A food chain consists of producers (green plants), consumers (animals and man) and decomposers (micro organisms). Basically there are two types of food chains: grazing food chain and detritus food chain. 

Example of food chain: Plants --> Mice-->Snakes--> Vultures

Food Web

In an ecosystem single food chains ne
ver occur. The same organisms may operate at more than one tropic level. So different food chains are inter connected. Thus, in an ecosystem several food chains are linked together and intersect each other to form a complex network called food web

Answer 2

Hey,
Friend,

●FOOD CHAIN

The sequence of living organisms in an ecosystem in which one organism consumes another organism to transfer food energy is called food chain.

• The food chain represents unidirectional transfer of energy.

• The size of any population is ultimately determined by the number of steps in a food chain.

●FOOD WEB

The interconnected food chains operating in an ecosystem which establish a network of relationships between various species is called food web.

•It shows the pattern of energy or nutrient flow throughout an ecosystem.

• The complexity of a food web depends upon the diversity of organisms in the system.
