Answer 1

Answer: (A)

Bacteria are important decomposers of the ecosystem. Because of their small size, they are also called micro-consumers. Green plants (producers) are also called transducers because they convert light energy into chemical energy. Primary succession also called Prisere. It starts in the barren area, never having vegetation of any type where no living organism ever existed. Cooled volcanic lava, sand dunes, igneous rocks, a newly exposed sea, or newly submerged terrestrial habitats in water, etc., are the areas where primary succession starts. It is very difficult for the pioneer community to get established in these areas and thus it takes a very long time. Lithosere (or Xerosere) refers to the sequence of successional stages that occur on bare rock, saline conditions, and sand.
