Because they live in different climates

Because they eat different types of food

Because they are different ages

Because they are different genders

A group of different species living together

A group of individuals of the same species living in the same area that breed with each other

A group of individuals of the same species living in different areas

A group of individuals that do not breed with each other

Less diversity increases the chances of survival during environmental changes.

Greater diversity within a population increases the chances for survival during environmental changes.

Diversity has no effect on survival chances.

Diversity only affects individual fitness, not population survival.

Mutation

It causes new traits to spread more slowly through a population.

Individuals tend to mate with those similar to themselves.

It increases the probability that all pairs will mate equally.

It limits the frequency of certain alleles.

Lactase; lactose

Lactose; lactase

Amylase; glucose

Sucrase; sucrose

The beaks are different colors to attract mates

The beaks are adapted to different types of food sources

The beaks help the birds fly faster

The beaks are used for building nests
