![]() ![]() For example, many herbivores disperse the seeds of the fruits as they move. This is helping the prey (in this case, the plants) also. This category includes animals that consume plants and plant products, such as cows, buffaloes, goats, sheep, deer and many more. Herbivores are the primary consumers in a food chain. Herbivores are animals that obtain all their nutrition from only plants and plant-based sources. These categories have been described below. All these predators can be broadly classified into three categories. There are various types of predators on Earth, owing to the massive biological diversity seen on our planet. The prey experiences a loss of energy and health, whereas the predator is in benefit. The predator is the organism that feeds on the other organisms, and the prey is the organism that is eaten by the predator. It refers to the interdependent relationship between the two organisms, the prey, and the predator, where energy flows from one organism to another. Predation, in biology, can be defined as a relationship between two different species organisms in which one of them acts as a predator capturing and feeding on the other organism, which serves as a prey. ![]() Most food chains begin with autotrophs (organisms that generate their own food), to primary consumers (herbivores, secondary consumers (carnivores and omnivores), tertiary consumers, and finally reach the decomposers. Every ecosystem or community is composed of one or more food chains. The word food chain defines the sequence in which the animals rely on one another to fulfil their nutritional needs. The definition of a food chain is a system in which a small animal is a food for a larger animal that is, in turn, the food for an even larger animal. For instance, a snake is the predator of a mouse, but it is also the prey of an eagle, as seen in the image below. Predators may also fall prey to other organisms, depending on where they fall in the food chain. Lions, tigers, sharks, snakes are some examples of predators. Predators usually fall into the carnivorous or omnivorous categories. The species which the predators eat are considered as the prey. Predators are those species that stalk and consume certain other organisms for food.
