Quick Answer: Which Of The Following Statements Is True About The Cycling Of Oxygen In A Pond Ecosystem?


How does oxygen cycle through an ecosystem?

Plants and animals use oxygen to respire and return it to the air and water as carbon dioxide (CO2). CO2 is then taken up by algae and terrestrial green plants and converted into carbohydrates during the process of photosynthesis, oxygen being a by-product.

During which of these processes is oxygen consumed?

1. When plants perform photosynthesis they consume oxygen and release carbon dioxide in the environment. 3. Aerobic reactions are those reaction that require oxygen as their fuel to occur.

What is oxygen cycle explain?

: the cycle whereby atmospheric oxygen is converted to carbon dioxide in animal respiration and regenerated by green plants in photosynthesis.

What is the main source of oxygen for the oxygen cycle?

Photosynthesis is the main source of atmospheric oxygen, which produces sugars and oxygen from carbon dioxide and water: An additional source of atmospheric oxygen comes from photolysis whereby high energy ultraviolet radiation breaks down atmospheric water and nitrous oxide into component atoms.

What is oxygen cycle and its importance?

The oxygen cycle is the cycle that helps move oxygen through the three main regions of the Earth, the Atmosphere, the Biosphere, and the Lithosphere. This also has some free oxygen produced from photosynthesis and other life processes. The largest reservoir of oxygen is the lithosphere.

What is the importance of oxygen cycle in the environment?

The oxygen cycle is an essential biogeochemical cycle to maintain the concentration and level of oxygen in the atmosphere. The oxygen cycle is one of the main reasons for the existence of life on earth. Without oxygen, the biosphere could not exist. However, Anaerobes can live without the presence of oxygen.

What is the purpose of these nodules?

What is the purpose of these nodules? The nodules contain bacteria which can convert atmospheric nitrogen into ammonia.

What is aerobic respiration in science?

Aerobic respiration is a chemical reaction that transfers energy to cells. The waste products of aerobic respiration are carbon dioxide and water.

During which process is oxygen used by plants?

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

What is importance of oxygen?

Oxygen plays a critical role in respiration, the energy-producing chemistry that drives the metabolisms of most living things. We humans, along with many other creatures, need oxygen in the air we breathe to stay alive. Oxygen is generated during photosynthesis by plants and many types of microbes.

What is oxygen cycle explain with diagram?

The atmosphere contains about 21% oxygen. The atmospheric oxygen enters the living organisms, as a gas required in respiration. During this process carbon dioxide and water are formed.

What are the steps in oxygen cycle?

Stage-1: All green plants during the process of photosynthesis, release oxygen back into the atmosphere as a by-product. Stage-2: All aerobic organisms use free oxygen for respiration. Stage-3: Animals exhale Carbon dioxide back into the atmosphere which is again used by the plants during photosynthesis.

What is the biggest source of oxygen on Earth?

Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize.

What is the oxygen carbon dioxide cycle?

The Oxygen – Carbon Dioxide Cycle During photosynthesis, plants give off oxygen as a waste product. Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant’s leaves. Oxygen moves out of the plant leaf through these same openings.

How oxygen is removed from the air?

The most common commercial method for producing oxygen is the separation of air using either a cryogenic distillation process or a vacuum swing adsorption process. Nitrogen and argon are also produced by separating them from air. This method is called electrolysis and produces very pure hydrogen and oxygen.
