How does the sense of smell help animals? Give two examples
Answers
Answer:
Science has found that most animals have a sense of smell, but the organ they use to smell can differ wildly from one animal to the next. Each basic category of animal has its own unique way of smelling. For instance, amphibians like frogs use nares, which are holes starting in the mouth and leading to the face, like human nostrils. Fish also use nares, taking in water that moves over sensory pads in their heads that tell their brains what they are smelling. Birds smell through nostrils found on their beaks. Mammal nostrils, on the other hand, are located on the nose. Mammals have a large range of smell, and some are better at it then others. Dogs, for example, are very good at sniffing, while elephants are even better; both of them can smell better than humans can.

Reptiles like lizards are even more unusual because they use their tongue to smell. They flick their tongue to pick up scent particles from the air, and when their tongue goes back into their mouth, it rests on the roof of the mouth, where special sensors interpret the scent.
Answer:
Most animals have a great sense of smell, but the animals that don't have a good sense of smell they use their other organs to sense any type of danger..
Animals can also release smells to send a message to other animals.
The strong sense of smell even helps them to find food, communicate, find a mate, sense of danger..
Sense organs allow animals to sense changes in the environment around them and in their bodies so that they can respond appropriately. They enable animals to avoid hostile environments, sense the presence of predators and find food.
