What are the two processes for which oxygen is needed?

What are the two processes for which oxygen is needed?

The three main process are photosynthesis, combustion and respiration are the process of oxygen cycle.

What are the two main processes of the oxygen carbon cycle?

In the natural carbon cycle, there are two main processes which occur: photosynthesis and metabolism. During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product.

What processes uses oxygen?

Processes That Use Oxygen

• Breathing – The scientific name for breathing is respiration. All animals and plants use up oxygen when they breathe.
• Decomposing – When plants and animals die, they decompose.
• Rusting – This is also called oxidation.
• Combustion – There are three things needed for fire: oxygen, fuel, and heat.

What processes release oxygen?

photosynthesis
The process of photosynthesis in plants releases oxygen into the atmosphere. Respiration by plants and animals, as they use the energy stored in food, and the process of decomposition of dead organisms, releases carbon dioxide into the atmosphere.

What is the process of taking in oxygen?

The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

What are the 3 processes necessary for the carbon oxygen cycle and how do they work together?

1) What are the three processes necessary for the carbon dioxide–oxygen cycle and how do they work together? Photosynthesis, respiration, and decomposition are processes that are responsible for maintaining the carbon dioxide–oxygen cycle. The process of photosynthesis in plants releases oxygen into the atmosphere.

Which process produces most oxygen?

It is estimated that 50 to 80 percent of oxygen produced on Earth comes from the ocean as a result of photosynthesis. The majority of photosynthetic organisms in the ocean are not true plants but either algae or photosynthetic bacteria.

What is the use of oxygen in our body?

Oxygen is a gas that your body needs to work properly. Your cells need oxygen to make energy. Your lungs absorb oxygen from the air you breathe. The oxygen enters your blood from your lungs and travels to your organs and body tissues.

Which of the following processes occurs during inhalation?

When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.

What is the process of oxygen cycle?

The entire cycle can be summarized as, the oxygen cycle begins with the process of photosynthesis in the presence of sunlight, releases oxygen back into the atmosphere, which humans and animals breathe in oxygen and breathe out carbon dioxide, and again linking back to the plants.

What process uses oxygen?

cellular respiration
Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.

What are the processes that produce oxygen?

Processes That Produce Oxygen

• Plants – Plants create the majority of the oxygen we breathe through a process called photosynthesis. In this process plants use carbon dioxide, sunlight, and water to create energy.
• Sunlight – Some oxygen is produced when sunlight reacts with water vapor in the atmosphere.
