Give definitions of (a) Succession (b) Pioneer species.
Answers
Answer:
Succession: A number of people or things sharing a specified characteristic and following one after the other.
Pioneer species: Pioneer species are hardy species which are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire. Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants.
