Question

Make sentences using the given set of words.
Respiration, dissolved, animals, air, aquatic

Answer 1

Hint: Nitrogen, oxygen, carbon dioxide, water vapour, and a few other gases make up air. It may also contain some dust particles. Oxygen promotes combustion and is required by all living organisms. The atmosphere is the air envelope that surrounds the earth.

Complete answer:
 If we connect the above words we will get a sentence as follows:
“Respiration in aquatic animals is done by dissolved air” or “Aquatic animals use dissolved air for respiration”.

Many forms of life, including fish, invertebrates, bacteria, and plants, require dissolved oxygen. These organisms, like those on land, use oxygen for respiration. When there is no light for photosynthesis, fish and crustaceans obtain oxygen through their gills, whereas plant life and phytoplankton require dissolved oxygen for respiration. The amount of dissolved oxygen required by each creature differs.

Bottom feeders, such as crabs, oysters, and worms, require very little oxygen, whereas shallow-water fish require more. Bacteria and fungi, for example, require dissolved oxygen as well. DO is used by these organisms to break down organic matter at the bottom of a body of water. Microbial decomposition contributes significantly to nutrient recycling.

If there is an excess of decaying organic material (from dying algae and other organisms) in a body of water with little or no turnover (also known as stratification), the oxygen at lower water levels will be depleted faster.

Note: Simple diffusion of gaseous metabolites is sufficient for respiratory function in very small animals, plants, and bacteria, and no special adaptations to aid respiration have been discovered. For many larger aquatic animals, such as worms, jellyfish, sponges, bryozoans, and other organisms, passive diffusion or active transport are sufficient mechanisms. There are no specific respiratory organs or organelles found in these cases.
