Key concepts
3 concepts
- 1
Ecosystems are intricate webs of life where organisms constantly interact, forming complex interdependent relationships.
- 2
In mutualism, both interacting species derive a net benefit, while commensalism describes an interaction where one species benefits and the other is neither significantly harmed nor helped.
- 3
Parasitism involves one organism benefiting at the expense of another, and predation is when a predator consumes prey.
