SYMBIOTIC RELATIONSHIP – In this topic, we are going to know the meaning of a symbiotic relationship and identify its five types.

SYMBIOTIC RELATIONSHIP

Also known as symbiosis, it is a type of close and long-term biological interaction between two different species. It is also defined as a intimate interaction between two or more species, which may or may not be beneficial to either.

The world is full of symbiosis. The term comes from the Greek sym, which means together, and bios, which means life.

Types

There are five main types, namely:

  • Predation
    • This type is defined as any interaction between two species wherein one species benefits by obtaining resources from and to another species. It is usually associated with with the classic predator-prey interaction where one species kills and eats another.
  • Competition 
    • Occurs when multiple organisms aim for the same, limiting resource. It can be interspecific, between different species, or intraspecific, between individuals of the same species.
  • Mutualism
    • Defined as any interaction between two species that benefits each other.
  • Commensalism
    • A type of interaction where one species benefits, while the other remains unaffected.
  • Amensalism
    • This type is defined as an interaction where the presence of one species has a negative effect on another but the first species is unaffected.
