Read the text and tell about homeostasis.

Maintaining life

For life processes to run smoothly, conditions inside an organism need to stay relatively stable. The process of keeping the internal conditions in a balanced state is called homeostasis.

Examples of homeostasis include keeping water levels balanced, controlling body temperature, and responding to external and internal stimuli.

Organisms have complex systems of checks and mechanisms to enable them to keep their internal state the same all the time.

UNIT 2

Read and translate the text, say what is biome.

Where Organisms Live?

Living things are adapted to exist in particular places. The climate (temperature, sunlight, and rainfall) affects the type of vegetation that grows, which in turn determines the animals that live there. An organism is also affected by the soil type, whether the place is on dry land or under water, and the presence of other organisms competing for food and mates. A huge habitat zone, such as an ocean or a desert, is called a biome. Similar biomes can exist on different continents that share the same conditions. Desert biomes, for example, exist in America, Africa, Australia, and Asia.

Read the text, classify the animals (reptiles, birds, etc.) and speak about the peculiarities of Britain's fauna.
