According to the theory of natural selection, organisms produce:
Correct answer: D. More offspring than supported
- A. Offspring according to the resources available
- B. Offspring to create resources
- C. To create resources
- D. More offspring than supported
Explanation
According to the 'theory of natural selection', organisms produce more offsprings, than those who can survive i.e. the environment can not support all offsprings produced so, only those offspring with traits, better matched to the environment, will survive and reproduce more effectively than others, who die off due to absence of traits that confer a selective advantage. This is the basis of evolution. Hence, option D is correct.Option A is incorrect, as it describes the scenario opposite to that of natural selection.Options, B and C, are both extremely similar and incorrect, as offspring consume the resources of the environment.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
