Why are animals different in different places?

Why are animals different in different places?

Just like you have to go to the store to get food, an animal leaves its “shelter” to get the things they need to live. If the animal’s needs aren’t met, it will move to a different habitat. Different animals need different habitats. A fish, for example, needs clean water in which to live.

How are animal different from each other?

Like all living things, animals grow, change, reproduce, and respond to their environment. They get the energy they need from eating food. animal’s body match up with other parts around a midpoint or line. Some kinds of animals have no symmetry.

Where did all the animals come from?

Genetic data suggest that multicellular animals evolved around 1000 million years ago; this is supported by fossil embryos from rocks in China that date back 600 million years.

Why do different plants and animals live in different habitats?

Animals tend to live naturally in specific areas. Different kinds of plants grow naturally in different areas too. Plants and animals will choose where they live mostly because of the water, food and climate of a specific are.

Why are there so many species of the same animal?

Just why some groups contain large numbers of species while others don’t has long puzzled biologists. One of the main explanations has been geological age – older groups of organisms are more diverse because they have simply had more time to accumulate greater numbers of species.

Why can different animals be grouped in more than one way?

Animals can be divided into many groups. These groups are decided based on their characteristics. All animals have some basic features in common. That does not mean they are the same.

Why are some species more diverse than others?

Species diversity It is a function of both the number of different species in the community (species richness) and their relative abundances (species evenness). Larger numbers of species and more even abundances of species lead to higher species diversity.

Why are there so many different forms of life on Earth?

Life on our planet is very multiform, as it is the result of multiple and varied processes of change and evolution from a common ancestor. The first type of life on Earth is made up of all the macroscopic life (animals, plant, fungi, algae, lichen…) and the microscopic protozoa.

Why are there so many different species of animals on Earth?

Because there are so many different types of environment on Earth. In order to survive, each species needs to find a habitat which provides it with enough food, space and shelter to live and reproduce. There is a huge difference in the conditions of the ocean compared to the desert and a forest compared to a lake.

What are some of the different types of animals?

Most people recognize that mammals such as dogs, tigers, pandas, and elephants, are all wild or domesticated kinds of animals. Also insects, fish, invertebrates, and birds are types of animals.

What makes a mammal different from other animals?

Mammals are characterized by their hair or fur, which all species possess during some stage of their life cycles; the milk with which they suckle their young, and their warm-blooded metabolisms, which, as with birds, allows them to inhabit a wide range of habitats, ranging from deserts to oceans to arctic tundra.

How many classes of animals are there in the world?

All species of animals are classed into two groups: Vertebrata (animals with backbones) and invertebrates (animals without backbones). The five most well known classes of vertebrates are mammals, birds, fish, reptiles, and amphibians.
