If every mammal was the same size, it would be hard to hide from the predator or stalk the prey. Every mammal is the size it needs to be to survive.
The answer is A) live in different environments
Mammals are vastly different sizes. For instance, a mouse and an elephant are very differently sized mammals.
why are raindrops different sizes?
Cells are different shapes and sizes because they have different functions. The functions dictate the shapes and sizes.
Mammals are not different to vertebrates. Well that's what ii guess
Most Australian mammals are marsupials unlike American mammals.
They are different sizes to aid the blind/visually impaired
Different mammals eat different food. Mammals occupy varying places on a food chain. Some mammals are vegetarians, they are primary consumers. Some mammals are carnivores, they are higher level consumers. Some mammals are omnivores.
it is due to natural variation and evolution. we all know that we are related to monkeys as we evolved from them. then cats are related to lions etc. Different species of dinosaur will have evolved from animals before them so are all different sizes like we are different sizes and have different features some physical like eye colour and others mental like personality. we are also different to other mammals. Genes can also cause a change in size and some dinosaurs are taller to reach plants on tall trees and some are smaller to hide from predators.
land mammals live on land, sea mammals live in the water.
No, reptiles and mammals are very different.
Yes they in fact go come in different sizes to accommodate the different sizes of trampolines. There are also some which are adjustable as well.
