Why is life able to exist in different environments?

Life exists in so many different environments because the organisms that live in them have adapted to them.

What do adaptations allow organisms to do?

Adaptations allow organisms to survive.

Who is adpated to live in different environmental conditions?

Organisms, including microorganisms, are adapted to live in different environmental conditions.

What are adaptations and what are three types of adaptations?

The features or characteristics that allow them to do this are called adaptations. Adaptations can be: 1) Structural 2) Behavioural 3) Functional

What are structural adaptations? Give an example.

These are features of an organism's body structure such as shape or colour. For example: Arctic animals like the Arctic fox have white fur so they're camouflaged against the snow. This helps them avoid predators and sneak up on prey.

How are whales adapted to live in cold environments?

Animals that live in cold places (like whales) have a thick layer of blubber (fat) and a low surface area to volume ratio to help them retain heat.

How are camels adapted to live in warm environments?

Animals that live in hot places (like camels) have a thin layer of fat and a large surface area to volume ratio to help them lose heat.

What are behavioural adaptations? Give an example.

These are ways that organisms behave. Many species (e.g. swallows) migrate to warmer climates during the winter to avoid the problems of living in cold conditions.

What are functional adaptations?

These are things that go on inside an organism's body that can be related to processes like reproduction and metabolism (all the chemical reactions happening in the body).

Give an example of a functional adaptation.

For example: Desert animals conserve water by producing very little sweat and small amounts of concentrated urine.

What happens to brown bears in winter?

Brown bears hibernate over winter. They lower their metabolism which conserves energy, so they don't have to hunt when there's not much food about.

Why do microorganisms have a huge variety of adaptations?

Microorganisms have a huge variety of adaptations. so that they can live in a wide range of environments.

What are extremophiles?

Some microorganisms (e.g. bacteria) are known as extremophiles - they're adapted to live in very extreme conditions.

Give an example of how extremophiles have adapted to their environment.

For example, some can live at high temperatures (e.g. in super hot volcanic vents), and others can live in places with a high salt concentration (e.g. very salty lakes) or at high pressure (e.g. deep sea vents).
