Was it beneficial or harmful for the Balanus barnacle to add the Chthamalus barnacle? Explain

harmful. (more info below)

Explanation:

Balanus may compete with Chthamalus through crowding or smothering, but Chthamalus can inhabit higher tide levels than Balanus since it is more immune to desiccation. Lower on the sea, the barnacles of acorn combine with the Endoclades (Turfweed) assemblage, and are also abundant on the shells of acorn. To conclude, it was a bad idea is add the balanus barnacle to the Chthamalus barnacle becuase balanus barnacles can crowd Chthamalus barnacle.

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.
