How do aquatic animals survive under water?

How do aquatic animals survive under water?

Note: The aquatic animals breathe underwater due to the presence of the dissolved oxygen in the water. They inhale the dissolved oxygen with the help of a feathery organ named gills. Gills are composed of blood vessels.

How do aquatic plants and animals survive in cold water?

When water boils at a certain temperature it turns into steam. When it is cooled to a certain temperature it freezes and becomes ice. 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.

How do aquatic plants and animals survive in water from where do they get oxygen?

the aquatic animals present in the water take oxygen in a dissolved manner and take oxygen in very fast manner because they are taking the oxygen in dissolved form rather than in air.

What makes aquatic plants able to live in water better?

What makes water plants better able to live in water? Spongy leaves allow the aquatic plant to float on the surface of the water. Leaves are broad and flat so the plant can float. Aquatic plants don’t have to stay in place.

Why can fish and other water animals and plants breathe in water?

When the water moves through the gills, the dissolved oxygen from the water passes through the thin walls of gills and blood vessels, and enters the blood. Apart from this, the waste carbon dioxide present in the blood passes into the water, thus helping fish to breathe underwater.

How do fish survive cold water?

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 plants and animals survive in Arctic region?

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. In this situation no plant and animals.

How do aquatic animals survive in water class 6?

The streamlined shape of sea animals is an adaptation for swimming in water. (2) Most of the sea-animals have gills which enable them to use oxygen dissolved in water for breathing. So, the presence of gills in sea-animals is an adaptation for breathing inside the water.

How do plants and animals help each other in the exchange of gases in the atmosphere?

Q9) How do plants and animals help each other in the exchange of gases in the atmosphere? Animals, during respiration, take in oxygen and release carbon dioxide gas. Plants, on the other hand, utilize this carbon dioxide gas in the process of photosynthesis to produce food and release oxygen in the atmosphere.

How do aquatic plants and animals survive in water for Class 6?

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.

Why are aquatic plants important for animal life?

Providing underwater cover for fish, amphibians, birds, insects and many other organisms. Providing a surface for algae and bacteria to adhere to. These organisms break down polluting nutrients and chemicals and are an important source of food for organisms higher in the food chain.

How do plants and animals living in water survive?

The aquatic plants and animals can easily survive in water. This is because water has 0.7\% oxygen present which the plants and animals use for breathing and processing life. The plants take in oxygen through the leaves where as the animals in water have specially built lungs known as gills for breathing.
