Question

The struggle for existence is a consequence of ______.

विकल्प

• each organism leaving more offspring than needed to replace itself

• the inevitable difficulty of coping with climatic conditions

• innate competitive tendencies

• territories and dominance hierarchies

Answer 1

The struggle for existence is a consequence of each organism leaving more offspring than needed to replace itself.

Explanation:

The struggle for existence arises because organisms produce more offspring than can survive given limited resources such as food and space. This overproduction leads to competition among individuals, resulting in a struggle for survival. It is not primarily due to climatic difficulties, innate competition, or social behaviors like dominance hierarchies, though those can influence survival as well.
