Answer:
The different species present in an ecosystem make the ecosystem balanced. The species of an ecosystem interact with one another in one form or the other. For example, the presence of a plant species will provide food for the abundant types of herbivores present in an ecosystem. A predator might feed on many types of preys. Hence, the presence of different preys will reduce the chances of a species from becoming wiped out from the ecosystem. Hence, all the organisms in an ecosystem are dependent on another in some way or the other.

This Perception has changed a little bit as time progresses but even in the 21st century many societies still believe the woman in a marriage/relationship should be taking care of the children more than the man/husband.
