Differentiate between primary and secondary succession. Provide one example of each.

Explanation

Primary succession :
1. The invading species are either lichens (on rocks) or phyto planktons (in water)
2. Rate of succession is slow
3. Climax is slow to reach
Secondary succession :
1. The invading species depend on the condition of soil, availability of water and type of seeds
2. Rate of succession is faster
3. Climax is reached faster.
