ADAPTATION OF FOOD
HERBIVORES: ANIMALS THAT EAT PLANTS
Cows, horses, goats and deer are the examples of herbivores.- Their sharp front teeth help them to cut grass and their flat grinding teeth at the back help them to chew the grass.
- The trunk of the elephant and the long neck of the giraffe help them to break and eat leaves from trees.
CARNIVORES: ANIMALS THAT EAT THE FLESH OF OTHER ANIMALS
Tigers, lions and foxes are the examples.- They have long, sharp teeth and claws which help them to tear the flesh.
- They have strong legs which help them to run fast to catch their prey.
- Snakes are carnivorous and use their scales to move fast on the ground. They swallow their prey fully.
- Eagles and vultures are carnivorous birds and have sharp claws and hooked beaks to catch their prey and tear its flesh.
OMNIVORES: ANIMALS THAT EAT BOTH PLANTS AND ANIMALS
Humans, bears and crows are omnivorous animals.- They have both flat and sharp teeth.
PARASITES: DEPEND ON OTHER ANIMALS FOR THEIR FOOD
Mosquitoes, fleas and leeches are parasites that suck the blood of other animals.- They do not have teeth. Instead they have sucking tubes in their mouth.
- They live on or inside other animal bodies to derive food from them.
- The animal which supplies food to the parasite is known as Host.
