This question is not well placed. It should be " a relationship between two organisms in which both benefit is called".

The answer is SYMBIOSIS

Explanation:

Living organisms tend to interact with one another in their natural environment. This interaction are of different types depending on the effect on the involved organisms. One of those interactions is SYMBIOSIS. Symbiosis is a relationship between two organisms in which both of the organisms benefit from one another.

An example is the relationship between the "CATTLE AND EGRET". The cattle provides food for the egret when they feed on the insect parasites on their body while the egret helps the cow get rid of detrimental parasites.

Homo erectus presumably evolved into Homo heidelbergensis, so the two species cover different time periods as well. Homo erectus lived from about 1.9 million years ago to about 800,000 years ago, whereas Homo heidelbergensis lived from about 800,000 years ago to as recently as 100,000 years ago
