Question

Differentiate between Primary succession and secondary succession by giving suitable examples in about 120 word

Answer 1

Primary succession is the process in which plants and animals inhabit a barren area for the first time, but secondary succession is the process in which plants and animals inhabit an area the second time which was previously destroyed.

Explanation:

• Both primary and secondary succession are the types of ecological succession in which the types of species inhabiting a particular area changes over time.
• Primary succession takes place in places where there was no trace of any plant or animal life, and the plants and animals are inhabiting the area for the very first time.
• These plants and animals species inhabiting an area for the very first time is called as pioneer species.
• The best example is Lichens.
• Whereas in secondary succession the plants and animals starts inhabiting an area which was previously inhabited by some other species but was destroyed in some natural calamities like wildfires, floods, etc.
• The inhabiting of any particular area for the second or subsequent times by any plant or animal species is called as secondary succession.
• Example, the deforested area left after shifting cultivation regrows into forests if left for some time.
