Question

how do animals track their food explain with examples for 6Class​

Answer 1

Answer:

Animals track their food with their excellent sense of smell. They can smell their prey from a kilometer away. Then they have their good sense of hearing They can hear rustling in the leaves and make out which animal it was. eg the lioness and tiger.

Pupil shape varies across the animal kingdom, Maldarelli explains. It doesn’t take a rocket scientist to figure out that goats have horizontal pupils and domestic cats have vertical ones — but why do they vary in the first place?

Pupil shape varies across the animal kingdom, Maldarelli explains. It doesn’t take a rocket scientist to figure out that goats have horizontal pupils and domestic cats have vertical ones — but why do they vary in the first place?Vertical slit pupils — like those sported by cats and geckos — might provide the optimal shape to dilate for use at night. But that hypothesis only explains half the story.

But that hypothesis only explains half the story. Researchers at UC Berkeley and Durham University in the U.K. compared pupil size across 214 species. Most animals (cats, foxes and snakes) with vertical pupils acted as ambush predators, sneaking up on their prey day and night. In contrast, animals with horizontal pupils tended to be grazing animals like horses and sheep — prey to predators with vertically-slitted eyes.

Stretching pupils horizontally allows more light to enter the eye from the sides, so grazers can better spot attackers in the periphery. Even when horses and goats bend their heads down, their pupils rotate to stay parallel to the ground, researchers observed.

Through vertical pupils, horizontal things show up blurry (or at least blurrier than vertical things). But blur can help animals estimate distance, and that helps the eye focus on the target as well — perfect for low predators that need to track prey that's also close to the ground.
