Answer:
<em>The correct option is b) competition among individuals for available food sources </em>
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.
The most famous definition of a species comes from the 20th century German-born biologist Ernst Mayr, who emphasised the importance of interbreeding.
Answer:
This is a symbiotic relationship of commensalism
Explanation:
Commensalism is when one animal in a symbiotic relationship gets something out of the relationship without harming or benefiting the other. If the fish were to be helping the shark, it would be mutualism (since they both get something out of the relationship). If the fish were to be harming the shark it would be a parasitic relationship. Since the fish is neither hurting or aiding the shark, it is a commensalistic symbiotic relationship!
