New Questions and Answers and Forum Categories Some common food chains are mentioned below:Īlgae→ Small→ animal → Small fish → Big fish -> Bird A few food chains can be long and may extend to the fourth, fifth or even sixth order of consumers. They are consumed by carnivores (flesh-eaters). Herbivores (plant-eaters) come next in the chain. In a freshwater aquatic ecosystem like a pond, the organisms in the food chain include algae, small animals, insects and their larvae, small fish, big fish and a fish-eating bird or animal (Figure 8.4).Ī food chain always begins with producers. In this food chain, energy flows from the grass (producer) to the deer (primary consumer) to the tiger (secondary consumer).Ī food chain in a grassland ecosystem may consist of grasses and other plants, grasshoppers, frogs, snakes and hawks (Figure 8.3). The grass, deer and tiger form a food chain (Figure 8.2). In a forest ecosystem, grass is eaten by a deer, which in turn is eaten by a tiger.

It may also be defined as follows.Ī food chain in an ecosystem is a series of organisms in which each organism feeds on the one below it in the series. A series of organisms through which food energy flows in an ecosystem is called a food chain. In this way energy gets transferred from one consumer to the next higher level of consumer. And the secondary consumer may be eaten by a tertiary consumer, and so on. The primary consumer is then eaten by a secondary consumer.
