Question

1.How do these five types of ecological relationships differ from each other?

2.Why is it important to have these kinds of ecological interactions?

Answer 1

1)

• These interactions may have positive, negative or neutral effects on either species' ability to survive and reproduce, or "fitness." By classifying these effects, ecologists have derived five major types of species interactions:

1. predation
2. competition
3. mutualism
4. commensalism
5. amensalism.

2.

• Individual organisms live together in an ecosystem and depend on one another. In fact, they have many different types of interactions with each other, and many of these interactions are critical for their survival. One category of interactions describes the different ways organisms obtain their food and energy.

so meaning of ecological interactions that a biological interaction is the effect that a pair of organisms living together in a community have on each other.
