Food Chain in Ecosystem!

For an ecosystem to work there has to be a flow of energy within it. The organisms of the ecosystem need energy in the form of food.

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.

A food chain in an ecosystem is a series of organisms in which each organism feeds on the one below it in the series.

In a forest ecosystem, grass is eaten by a deer, which in turn is eaten by a tiger. The grass, deer and tiger form a food chain (Figure 8.2). In this food chain, energy flows from the grass (producer) to the deer (primary consumer) to the tiger (secondary consumer).

A food chain in a grassland ecosystem may consist of grasses and other plants, grasshoppers, frogs, snakes and hawks (Figure 8.3).A Food Chain in a Grassland Ecosystem

A food chain always begins with producers. Herbivores (plant-eaters) come next in the chain. They are consumed by carnivores (flesh-eaters). A few food chains can be long and may extend to the fourth, fifth or even sixth order of consumers.Some common food chains are mentioned below:

Plants → Deer → Lion

Plants → Worm→ Bird → Cat

Plants→ Grasshopper→ Frog→ Snake→ Hawk

Algae→ Small→ animal → Small fish → Big fish —> Bird

 

Examples of Food Chains

Food chain refers to the sequence of events in an ecosystem, where one organism eats another and then is eaten by another organism. It starts with the primary source like the sun or hydrothermal vents where producers make food, continues with consumers or animals who eat the food, and ends with the top predator.
