Answer:

disruptive selection

Explanation:

Disruptive selection may be defined as a type of a natural selection which selects against some average individual in a given population. These makeup of such a type of the population shows the phenotypes of both the extremes of characteristics but they have very few individuals in the middle.

Disruptive selection is also known as diversifying selection.

In the given context, the beaks of an African seedcracker finches may be small or may be large but they are not of the intermediate size. Such a selection is known as disruptive selection in species.

Humans have fished the prawns and small fish in an estuary to near extinction. Describe the impact this could have on the bacter
Yuri [45]

Answer:

Overfishing is one of the major concern no a days in aquatic systems. overfishing is resulting in the extinction of aquatic organisms and it can lead to several damage to other living organism.

Prawns and small fishes are important organisms in food web or in aquatic system as they maintain the bacterial level or other microorganism level in control.

Prawn and small fishes utilize oxygen and nutrients present in water to survive, if they will get extinct the amount of nutrient and oxygen left will be used by the bacteria and mold living in the system which can have bad impact on human and other organism.

Heron and pelican populations depends on prawn and small fishes for survival as they feed on them and when there will be not sufficient population of  prawn and small fishes, there are chances that heron and pelican populations can also get extinct.
