Flashcards in Intraspecific 1 Deck (11):

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.
