Answer 1

Answer:

The correct option is b) competition among individuals for available food sources

Explanation:

Natural selection can be described as a phenomenon which describes that organisms which are better adapted to survive in an environment are able to live and pass on their characteristics to their children. Organisms develop characteristics with the passage of time which enable them to survive in different areas. Competition among the finch population led to the development of different finch sizes.
