Describe how photosynthesis and cellular respiration power ecosystems of all kinds on this planet.

Photosynthesis:

Photosynthesis can be described as a process by which plants convert water and carbon dioxide into glucose and oxygen in the presence of sunlight. The glucose made by this process gives energy to the plant to carry out life functions. This energy is transported to all the organisms in the trophic levels when the plant is consumed by the primary consumers. The oxygen which is produced as a by-product of photosynthesis is essential for breathing of animals and humans. Hence, maintaining the ecosystem.

Cellular Respiration:

Cellular respiration can be described as a process by which glucose and oxygen are converted to carbon dioxide and water. A huge amount of energy in the form of ATP is released by this reaction. ATP is used by almost every cell of the organism to carry out its life functions. Hence, for the survival of an ecosystem cellular respiration is essential.

Photosynthesis and cellular respiration exchange carbon and oxygen in the ecosystem.

EXPLANATION:

Plants carry out photosynthesis by which they produce oxygen and consume carbon-di-oxide. This oxygen is inhaled by the humans and animals and they breathe out carbon-di-oxide. Cellular respiration takes in oxygen and gives out carbon-di-oxide.

Cellular glucose is taken from photosynthesis by the cellular respiration to produce ATP.In photosynthesis, water breaks down which produces oxygen and in cellular respiration, water is formed by combining oxygen and hydrogen. Thus, both these processes are building blocks of ecosystem keeping levels of oxygen and carbon-di-oxide stable levels.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
