What are the competitive relationships in the natural community (give examples)?

| November 26, 2020 | education

1. Positive (symbiosis)
This is when organisms benefit and do not badly to anyone.
– Mutualism
Living organisms have so adapted to live together that they cannot live without each other! For example, mushrooms and algae in lichen.
– Protocooperation
Relationships for the strong and independent. When two are better, but you can also separately.
Actinia and hermit crab.
– Commensalism
When one is good, and the other does not care.
For example, a fish stuck to a shark.

2. Neutral
The name speaks for itself. Living organisms do not affect each other in any way in the ecosystem.

3. Negative
– Predation
When one creature feeds on another. However, it kills him.
– Parasitism
The parasite uses the host as a place to live and a source of food, and harms the host (as opposed to commonsism). But killing the host is not profitable for the parasite, because he himself will die.
– Competition
Everything here is in the best traditions of the theory of evolution.
