How do many of the mammals that inhabit deciduous forests deal with the conditions of the winter season?

they migrate to warmer areas.
they forage or hunt at night.
they develop symbiotic relationships.
they hibernate or stockpile food.

D.) They hibernate or stockpile food.

Explanation:

This question can be confusing for some, so I'll go through the process of elimination to make it easier for everyone. Option A is definitely not correct; only birds migrate to warmer areas. Option B is incorrect because depending on the location of where the mammal is, they can possibly freeze and there won't be enough food to survive. Option C makes no sense; yes, animals can benefit from one another in a symbiotic relationship, but that's not going to keep them warm or alive.

Hope this helps :)

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.
