Why an animal needs to move quickly?

Answer 1

So they can escape from the animals that are pray on them. Animals need to move to get food and get away from danger. Animals need food for energy.

Answer 2

The reason that smaller birds flap their wings faster than large birds in flight is because large birds are heavier and their wings can't handle all that weight so smaller birds don't weigh a lot and their wings do handle them.

Big birds have big wings, so they can glide in the wind, small birds' wings are too small to glide in the wind. Big wings can displace (push) more air. If little birds had big wings, they too would be fluttering less! It has to do with the rate of the heartbeat. Smaller birds have a much faster heartbeat than larger birds do so in turn flap their wings at a faster rate. It is a combination of factors, though I'm not sure if only one is more important than another...however, they all contribute into the same end product and one common factor: smaller birds are Birds of Prey. 1) Wing span: smaller the bird, shorter the wing span from wing tip to wing tip. This makes it necessary to flap more frequently to keep the lift required to compensate for their weight. 2) Environment: small birds need to hide from predators, therefore they live in mostly forested or grassy places to find safety in the form of shelter. This also makes it necessary for them to be able to make sudden maneuvers and sharp turns - which a larger wingspan would hinder. 3) Escape: needing to flee suddenly requires one to be able to get lift with little momentum...if they were larger (heavier) and had a greater wing span this would add too much bulk and slow them down. Predatory Birds: The opposite of all of the above, plus: 1) Predatory birds hunt from heights of up to 100's if not 1000's of feet; they rely heavily on their eyesight to locate their prey. The length and breadth of their wings actually assists them to compensate for their weight and slower metabolism than smaller birds. They are dependent on the thermal streams (currents of warmer air) in the atmosphere to find lift and "glide" rather than actively fly to stay aloft for long periods of time. For these reasons, in most cases, larger birds and their slower flapping rate cannot actively "fly" for long distances like smaller birds can. because otherwise they dont have as much power to fly

because their so small they flap their wings faster because it takes a whole lot more energy than it does with larger birds

Answer 3

Well its because Small birds have small wings so they don't have as much air under the wings unlike big birds so in place of that the small birds beat their wings faster which common sence tells you that the heart rate goes up

Answer 4

small animals sleep more than big animals because of their heart

small animals have fast heartbeates

but big has slow

so the faster heartbeates you have the more tired you get by doing works

( i think this is the answer0

Answer 5

Because small animals are smaller so they can move quicker and some have longer legs.

Answer 6

im pretty sure its cause the small animal has a smaller stomach then the bigger animal. like your baby sis or bro eats less than you of your parents

Answer 7

Animals move quickly for a variety of reasons such as to find food , a mate or to escape from hunters

Answer 8

So they can escape from the animals that are pray on them. Animals need to move to get food and get away from danger. Animals need food for energy.

Answer 9

An Animal Needs To Move Quickly To:-

- Survive from their predators.

- To get food and energy.

Answer 10

They needs to move quickly because they have to find their food and essential for survival.
