EVERYDAY SCIENCE

Detailed explanation-1: -Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community.

Detailed explanation-2: -Ecological succession is a series of progressive changes in the species that make up a community over time. Ecologists usually identify two types of succession, which differ in their starting points: In primary succession, newly exposed or newly formed rock is colonized by living things for the first time.

Detailed explanation-3: -The first organisms appearing in the regions of primary succession are pioneer species (usually lichens or mosses). They are the first species present. They must be strong and hardy.

Detailed explanation-4: -Common examples of pioneer species include bacteria, lichen, mosses, and fungi. In the ocean they can be phytoplankton, zooplankton, and algae.

Detailed explanation-5: -Pioneer species are hardy species that are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by wildfire.
