Types of Associations

Ecology is defined as the study of living organisms and the relationships or interactions between them and their environment. The interactions between plants and animals in their environment are usually described as biotic interactions or associations. There is a close association between the biotic and abiotic components of the environment. Both affect each other and are equally important for the ecosystem.


Symbiosis is a time period for all associations through which all or a number of the species concerned advantages or loses. It’s interdependence of various species, that are generally referred to as symbiotic. Based mostly upon the precise relationship between the species concerned in a symbiotic affiliation, at the least one member advantages. There are three principal forms of symbiosis


Symbiotic relationships could also be grouped as:

  1. Parasitism
  2. Mutualism
  3. commensalism

Lichens of the Splash Zone of the Intertidal Region

Lichens are actually a combination of two entirely different types of living organisms, an alga and a fungus.

The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.

He or she does the necessary corrections when and where  the needs arise.
