Step 4: Explain why the body responds to stimuli. Create a slide titled Reason(s) the Body Responds to Stimuli.
On the slide, give an explanation as to why the body responds to stimuli.
Include real-world examples of how the body responds to stimuli.
Place text in the notes section below the slide explaining the information presented on the slide. This text will act as the script for your presentation.
Remember to save your work as you go.

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.
