Discussion Proper:
Ecological relationship
Ecological communities consist of interacting or potentially interacting
species in the same environment.
This is what we call ecological relationship.
Types of ecological relationship:
1) Mutualism
Mutualism is a relationship in which both species benefit.
For example, bees get the nectar they need to make honey by traveling
between flowers.
2) Commensalism
Commensalism is a relationship in which one organism benefits while the
other is neither helped nor harmed.
For example, birds that live in the hollows of trees are commensal.
3) Amensalism
Amensalism is an interaction where an organism conflicts harm to another
organism without any cost or benefits received by itself.
For example, the black walnut tree that secretes chemical to it's
neighboring plants.
4) Parasitism
Parasitism is a relationship in which one organism benefits and the other
organism is harmed, but not always killed.
The organism that benefits is called the parasite, and the one that is harmed
is the host.
For example, a tick on a dog.
5) Predation
Predation is when one organism eats another organism to obtain nutrients.
The organism that is eaten is called the prey.
For example, lion that eats gazelles.
6) Competition
Competition is when individuals or populations compete for the same
resource, and can occur within or between species.
An example are lions and hyenas that compete for prey.
