Explain the food web of the ecosystem?

The food web is defined as a collection of food chains which are interconnected at multiple trophic levels. They form many feeding connections in the different organisms of biotic community. It increases the stability of ecosystem. It provides other source of food and allows the endangered species to grow. The food web is modified by the taste and food habits of organisms. The availability of food and other factors are very important for its survival. In the sunderban forests the tiger eats the fishes and crabs when their taste of food is not present. There are few organisms which are present at more than one trophic levels. For example, the human beings are herbivorous at one trophic level and are carnivorous at the other trophic level. There are certain varieties of cats which feed on mice as well as on the birds. These are known as wild cats. There are wolfs which feed on fox along with the deer. The concept of food web looks more ecological than the concept of food chain. The rabbit cannot kill by starvation if his preferred plant is reduced in the quantity. It can feed on the other plants. They can recover from loss by the preferred ones. The foxes, wild dogs and wild rabbits prey on the rabbits. As the number of rabbits decreases they act on the other preys which include the mice and shrews. In this span of time rabbit increase their number. There are different types of food chains in the food web. It may be predator or parasitic or saprophytic food chain. The predator food chain consists of the plants and move towards the animals. The parasitic food chain consists of the organisms which differ in their size. The saprophytic food chain consists of the microorganisms and dead animals.
