Answer 1

Symbioses are close interactions between species that have evolved over long periods of time. When these interactions enhance the reproduction and population growth of both species, they are called mutualisms. Symbiosis involves two species living in a relationship that is mutualistic, parasitic or commensal. In mutualism, each individual has a benefit from the activity of the other.

Answer 2

Symbioses are close interactions between species that have evolved over long periods of time. When these interactions enhance the reproduction and population growth of both species, they are called mutualisms. 
In mutualism the relationship benefits the two organisms, the relationship can be within the species, between living things fro two different species among others. Example is the digestive bacteria and humans; Some food cannot be digested, therefore when these foods are consumed, the bacteria in the digestive tract feed on these foods, therefore the bacteria stays alive and humans gets helps in digestion.
