Study Notes
Interactions in Ecosystems
- Competition: Involves organisms vying for the same ecological resource (e.g., food, space, light) in a shared location, which can lead to resource depletion.
- Commensalism: A relationship where one organism gains benefits while the other is unaffected, exemplifying a neutral interaction between species.
- Mutualism: A symbiotic interaction where both organisms benefit from the relationship, enhancing survival or reproduction for each party involved.
- Parasitism: A relationship in which one organism (the parasite) benefits at the expense of another organism (the host), often resulting in harm to the host.
