Animals and plants have certain characteristics that help them survive and reproduce. What are these characteristics called?

• characters

• features

• adaptations

• adaptions

When predator numbers increase, prey numbers decrease because

• There are more predators to eat the prey

• There are more prey to eat the predators

• The predators decrease in number

• The predators run out of food

When the number of prey decrease, the number of predators also decrease because

• the predators start to reproduce

• the prey start to reproduce

• the predators start to die of starvation

• the prey numbers are rising

A scientific word used to describe the differences between organisms in the same species is

• features

• characteristics

• variations

• adaptations

Some variations are due to the chemical we inherit from our parents. This chemical is called

• cells

• DNA

• nucleus

• cytoplasm

Some variations are caused by our surroundings. These variations are known as:

• inherited variations

• discontinuous variations

• continuous variations

• environmental variations

An example of a continuous variation is (more than one answer)

• weight

• height

• eye colour

• shoe size

An example of discontinuous variation is (more than one answer)

• number of fingers

• length of hair

• blood type

• eye colour
