succession

And after a disturbance

Which is an example of primary succession?

1. Glacier retreat
2. Abandoned farmland
3. Flooded forest area
4. Volcanic island formation

What is secondary succession?

1. Always takes longer than primary
2. Occurs after disturbances
3. Begins on bare surfaces
4. Starts with existing soil

What is primary succession?

1. Follows agricultural activities
2. Occurs after forest fire
3. Starts without soil
4. Development on bare rock

What type of succession does this picture show?

1. Primary succession
2. Secondary succession

When there is succession in an ecosystem then...

1. The total biomass will decrease
2. The number of species in the system wil remain constant
3. The number of species in the system will increase
4. The number of species in the system will decrease

What is the order of succession shown in this figure?

1. A, B, C, D
2. A, D, C, B
3. C, A, D, B
4. C, D, A, B

As succession progresses, animal species diversity increases due to the fact that

1. less soil is being created
2. food choices increase
3. precipitation rates stabilize
4. temperatures moderate
