which behavior is this an example of?
competition

variation in a population
artificial selection

B) Overpopulation

Explanation:

overpopulation

Explanation:

Overpopulation is the term used to refer to a situation where the population of a certain living being is very large, greater than the natural resources of that ecosystem can support. This occurs when there is a number of births of this species, much greater than the number of deaths. In other words, we can say that overpopulation is an imbalance between the ecosystem and the number of members of a given population.

An example of this can be seen in the question above, where afrog have more off spring than can survive on available resources.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
