How aquatic animals live in cold region?

Aquatic animals live more in cold regions because the solubility of O2 in water is more at low temperature and therefore the amount of dissolved O2 is more in the water of cold regions.

How do fish living in extremely cold water survive?

Fish have several adaptions to survive a winter below the ice. First, they are cold blooded meaning their body temperature matches their environment. Colder temperatures mean a reduction in their metabolism. This slows numerous metabolic processes, such as respiration, digestion, and activity level.

How do aquatic animals survive at subzero temperature?

When the temperature goes below 40C , the density of water decreases, and thus no more water sinks. Henceforth, the water at the top is at the 00C and the bottom is 40C . These how the fish or the marine life is survived even under the thick layer of ice.

Why is it that aquatic life still survive in frozen lake?

The surface water finally freezs while the lower layer remain at 4c as ice is a bad conductor of heat freezing in the lower layer is a very slow pprocess. Thus underneath the frozen layer fish and other aquatic animals and plants survive.

How do aquatic animals survive?

Aquatic animals have various structural modifications in their body to adapt to the aquatic habitats. Some of the adaptations of aquatic animals are: Their body is streamlined and hence, they can swim easily. They have gills as the respiratory organs.

How do aquatic plants and animals survive in cold regions?

Answer. The aquatic plants and animals can survive in cold regions because of the property of anamalous expansion of water due to which the bed of the seas, rivers or oceans do not freeze,it just remains at 4°C and hence aquatic life is saved from cold in cold regions.

How do aquatic animals remain alive even after the rivers or lakes freeze in winter?

Answer: It is possible for aquatic animals to remain alive even though rivers and lakes freeze in winter because not the whole water bodies freezes. In cold countries the temperature of the water body decreases as a result of which ice is formed at the top . However water at the bottom does not freeze up.

How do fishes and aquatic animals survive in winters when the pond gets covered with thick ice?

Due to the anomalous expansion, only the upper surface to water gets frozen into ice. As density of ice is less than that of water, ice floats on water. The deeper layers of the pond help aquatic life to survive as the temperature remains a bit higher than the temperature of the upper layers. Hope it helps u.

How does aquatic animals survive in water?

Aquatic plants and animals are able to survive in water as water contains 0.7\% of dissolved oxygen which is taken inside their body by specially designed organs like gills and by general body surface in plants.

How do the aquatic life survive in extreme cold climates when the temperature of the water is below zero and the surface of the water is frozen ice?

After sufficient thickness of ice is formed it prevents further loss of heat from the bottom layers of water. This is why fishes and other aquatic animals and plants can survive in ponds and other water bodies even when the atmospheric temperature reaches or is well below 0 degrees.

How do aquatic plants and animals survive in water in winter?

When water boils at a certain temperature it turns into steam. Underneath the frozen upper layer, the water remains in its liquid form and does not freeze. Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds.
