1

Define competition.

An interaction between individuals brought about by a shared requirement for a resource in limited supply.

2

What are the results of competition?

A reduction in the survivorship growth and/ or reproduction of at least some of the competing individuals.

3

Define population.

A group of interbreeding individuals of the same species/ the unit of evolution.

4

Give the equation that describes a graph of a population which reproduces at one time.

Nt+1 = NtR

N = number in population
t = time
R = replacement rate.

5

Give the equation which describes a graph of a population which reproduces continuously/ exponential growth equation.

dN/dt = rmaxN

N = number in population
t = time
r = intrinsic rate of increase.

6

How can you find the value of r using a logarithmic plot of population growth?

r = gradient of line.

7

What is r?

Intrinsic rate of increase.

8

If r=0 then the population...

Stays the same.

9

If r>0 then the population...

Increases.

10

If r

Decreases.

11

What is R?

Replacement rate.
