During the winter, many fish eat very little.
some students thought this might be because
less oxygen is dissolved in the cold winter water
than in the same water during the warm sum-
mer months. the students tested the water and
found that cold water holds more dissolved
oxygen than warm water. they also discovered
that the fish have nearly as much food available
during the winter as in the summer.

explain why the fish eat very little during the
winter. [1]

Fishes eat very little during the winter as their metabolism slows down as their metabolism slows down.

Explanation:

Fishes are cold blooded animals and their body temperature is regulated with the change in the water temperature. When the water temperature becomes cold the fishes slow down in feeding. Fishes during winter undergoes certain changes in their body which slows down their metabolism rate.

When their metabolism slows down they will not stop feeding completely but lessen their feeding habit. During winter they also become less active. They seek pocket holes and go to that particular place and stay still. This helps them conserve energy.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
