What are symbiotic relations?

Answer 1

there are three different symbiotic relationship:

1. there is mutualism which means that one both species benefit from having the other around

2.there is parasitism which means that one species benefits while the other does not or even dies

3. there is commensalism which means when one species is around the other, one species benefit and the other just stays the same and neither benefits nor doesn't benefit

A nice example of 1 above would be the mitochondria that you have in each of your cells. Without you, they die. Without them, you will have a less enjoyable existence, for they manufacture some chemicals (ATP) that you need for energy, and of which your other (innate) source is much less efficient.

An example of 2 is such diseases such as influenza and Scarlet Fever.

For 3, we have such innocent behaviour such as plants perching in the forks of a tree - adding nothing to the tree, and merely gaining altitude from the tree.
