1. Read the text and answer the questions using whole sentences:
Cells are the building blocks of the living world. Living things as diverse as bacteria, algae, fungi,
protozoans, animals, and plants all consist of one or more cells. Cells are made up of components that
help living things to eat, respire, excrete wastes, and carry all of the necessary functions of life. The
components of a cell are organized to do the three functions (main functions) of living things are:
1. Nutrition: all living things have ways of taking in the substances they need to grow and survive.
2. Relation: Living things have a relationship with the environment that surrounds them. Humans use
their senses (seeing, hearing, smelling, tasting, touching) to relate with the world.
3. Reproduction: all living things are born, live for a period of time and then die.
a)
b)
c)
d)
e)

7. Read the text and answer
Biodiversty is the variety of life on Earth in all its forms. It is the result of evolution, a slow process
which began with the first life forms and still coontinues today. Species change and adpat to the
enviroment.
Biodiversity varies tremendously throughout the worl. It is influenced by climate and habitats.
Some regions have lost some of their biodiversity because plant and animal species have been
severely reduced or even destroyed by deforestation, uncontrolled hunting and fishing, pollution and
other factors.
