For many generations, a forest has been the home of a single species of bird; these birds primarily eat insects off the forest floor. One year, humans living in the area accidentally introduce a new species of bird to the forest. This new species has the same diet as the existing species. Which description predicts what will most likely result from these two species of bird living in the same
ecosystem? (5 points)
O Both bird species cannot occupy the same niche and, therefore, one species will die off.
Both bird species would share the forest and have plenty of food and resources.
One bird species will adapt and feed on different organisms in the forest.

The established species will battle the introduced species of bird until death.

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.

1. is geographic distribution

2 is increasing complexity

3 is transitional forms
