1
Q
State the 3 components of biodiversity.
A
- genetic diversity
- species diversity
- ecosystem diversity
2
Q
What is genetic diversity?
A
The number and frequency of alleles in a population
3
Q
Why are all populations within a species important?
A
If we lose one population, we potentially lose some of its genetic diversity
4
Q
What is the advantage of greater genetic diversity?
A
Greater ability to adapt to changing conditions
5
Q
What two things make up species diversity?
A
- species richness
2. relative abundance
6
Q
What does species richness mean?
A
The number of different species in an ecosystem
7
Q
What does the term relative abundance mean?
A
The proportion of each species in the ecosystem
8
Q
A community with one dominant species will tend to have greater/lower species diversity?
A
lower
9
Q
What is ecosystem diversity?
A
The number of distinct ecosystems within an area.
