The Hawaiian island of Mauna Loa is an active volcano. In areas where lava no longer flows, primary succession is taking place. Which of the following is an example of a pioneer species that can be seen here?

Algae

Orchids

Pineapple trees

Sugar cane

Verified Answer :

Algae. These pioneer species don't need much to survive, therefore, common pioneer species are bacterial organisms and fungi.

Answer: Algae

Explanation:

  • Primary succession is the type of succession which occurs in an area which was previously unoccupied and thus, has no formed soiled substratum.
  • A pioneer species is the one which are the first to colonise an area.
  • Now, when the primary succession has to take place, species like orchids, pineapple trees and sugar cane cannot be pioneer species as they require a nutrient rich and well developed soil substratum for their growth.
  • However, species like algae are very hardy and can begin their growth on nutrient deficient place with the available moisture. These can easily survive in a hostile environment and further pave the way for higher species and increase the diversity of a region.

Thus, in areas where lava no longer flows and primary succession has to take place, only algae can be the pioneer species.
