From the given statements, (d) Both Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1
Explanation:
- According to Malthusian theory, natural resources(like food) will be unable to keep up with population expansion. It increases the demand of resources which leads to struggle between organisms.
- This struggle for existence is clearly given by Darwin's work "On the Origin of Species" where he explains the concept of survival of the fittest.
- To ensure the survival of their species, organisms reproduce numerous off springs. Due to limited resources the organisms are forced to compete for their survival.
- Hence we can conclude that the increase in population leads to struggle for existence among the organisms.
