Apopulation of herbivores is at its carrying capacity for its habitat. which factor is likely to result in a sudden rise in population that far exceeds the carrying capacity? a.) birth of young b.) emigration c.) immigration d.) introduction of a new limiting factor

C). immigration

Carrying capacity is the property of ecosystem which indicates the number of individuals of population of species or group of species an ecosystem can sustain in terms of availability of resources (food, shelter). A population of herbivores is at it's carrying capacity for it's habitat. Immigration is the arrival of members of species to a new habitat for the purpose of deriving resources not found in their previous habitat or new habitat is more suitable then previous habitat. Immigration will increase the number of individuals in the ecosystem. Therefore, immigration will result in a sudden rise in a population that far exceeds the carrying capacity.

C.) immigration

I just did the test on plato

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.
