What is mutualism in ecological terms?

Back

Mutualism is a type of symbiotic relationship where both species involved benefit from the interaction.

Front

Can mutualism be defined as any close relationship between different species?

Back

False. Mutualism specifically refers to relationships where both species benefit, not just any close relationship.

What is an example of a symbiotic relationship where one species is harmed?

Back

An example is a parasitic relationship, such as a tick feeding on a mammal.

How does competition affect biodiversity in an ecosystem?

Back

Competition can reduce biodiversity as dominant species may outcompete others, leading to a decrease in the number of different species.
