The high heat capacity of water prevents fish body temperatures from changing during the winter.
Answer:
Skin,muscles and metabolism play a significant role in maintaining his body temperature
Explanation:
Role of skin
In cold environment the blood vessels of the skin constrict to prevent the loss or liberation of heat from his(jim) body.
Role of muscles
The one of principle function of muscle is to store glycogen.The stored glycogen of jim"s muscle undergo glycogenolysis to generate heat inside his body.
Role of metabolism
In cold environment the rate of aerobic respiration and other catabolic reactions such as beta oxidation of fatty acid occur to generate energy in form of heat in his body.

Freshwater wetlands are defined as the lands which have natural supply of water for the whole season due to geological or ecological factors such as tidal flows, connections with groundwater or flooding rivers.
There are three main types of freshwater wetlands swamp, marsh and bog.

Marsh is found near lake, tidal water or rivers and remain flooded periodically. Marsh are the grassy areas covered by shallow water and help to overgrown with coarse grasses, rushes and sedges.
Bog is defined as an area where moss or mots decomposes slowly and form peat . They are characterized by acidic waters, a floor covered by a thick carpet of sphagnum moss and spongy peat deposits. they are generally found in northern climates which support precipitation of water.
