NEET BIOLOGY

Detailed explanation-1: -True predators. These usually kill their prey, and consume many prey organisms during their lifetime. Carnivores, animal-eating organisms, are typical true predators.

Detailed explanation-2: -Predator: an animal that kills and eats other animals. Context: Hawks and coyotes both eat small rodents; they are predators. Prey: animals that are killed and eaten by other animals. Context: Rabbits and crickets are both eaten by bigger animals; they are prey.

Detailed explanation-3: -Often, the predator is larger than its prey. The larger animal consumes the smaller ones as their food as mostly seen in seas (where large fishes are preying on small fishes or insects). However, there are instances as well when small animals are preying on large ones and this is not an easy task.

Detailed explanation-4: -Prey are animals which are hunted for food by carnivores and omnivores alike.

Detailed explanation-5: -The geometric mean sizes of prey and predators increase as the habitat of webs changes from aquatic to terrestrial to coastal to marine. Within each type of habitat, mean prey sizes are always less than mean predator sizes, and prey and predator sizes are always positively correlated.
