What are the two major biological processes involved in the oxygen cycle?
In the biosphere the major oxygen cycles are photosynthesis and respiration. In these two processes of the oxygen cycle it is interconnected with the carbon cycle and the water cycle.
What are the 2 main process involved in the cycling of carbon?
Human Impacts: Fossil Fuels In the natural carbon cycle, there are two main processes which occur: photosynthesis and metabolism. During photosynthesis, plants use carbon dioxide and produce oxyge and during metabolism oxygen is used and carbon dioxide is a product.
Which two biological processes play a role in cycling carbon and oxygen?
Photosynthesis by land plants, bacteria, and algae converts carbon dioxide or bicarbonate into organic molecules. Organic molecules made by photosynthesizers are passed through food chains, and cellular respiration converts the organic carbon back into carbon dioxide gas.
Which of the following processes produces oxygen in the oxygen cycle?
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. In the process they also create oxygen which they release into the air.
What are the processes involved in the use of oxygen and carbon dioxide in the cycle?
When they're exposed to light, green plants use carbon dioxide from the atmosphere to manufacture living matter and release oxygen into the air. This process is called photosynthesis. Carbon dioxide is produced through the respiration of animals and plants, which consume oxygen and release carbon dioxide.
What is the process of oxygen cycle?
In the biosphere, the main processes in the oxygen cycle are respiration and photosynthesis. During respiration animals and humans breathe by consuming oxygen to be used in the metabolic process and exhale carbon dioxide. Photosynthesis is the reverse of this process and is done by plants and plankton.
Which of the following process is responsible for the release of oxygen by plant?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What are the two main biological processes?
Cellular respiration and photosynthesis are biological processes in which matter and energy flow through the biosphere. These two processes are responsible for the exchange of oxygen and carbon dioxide between living organisms and the environment.
Which biological process is responsible for adding oxygen regularly to the atmosphere?
photosynthesis The answer is tiny organisms known as cyanobacteria, or blue-green algae. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen.
Which biological process is responsible for adding oxygen to the atmosphere?

What are the two stages in photosynthesis?
The stages of photosynthesis There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.
What biological process brings oxygen into the atmosphere?
Photosynthesis Photosynthesis uses carbon dioxide and water to assemble carbohydrate molecules (usually glucose) and releases oxygen into the air.
What are the two stages of photosynthesis quizlet?
What are the two stages of photosynthesis? 1=light reactions/light dependent reactions. 2=the calvin cycle/light independent reactions.
What two main products result from photosynthesis?
Photosynthesis takes the energy of sunlight and combines water and carbon dioxide to produce sugar and oxygen as a waste product.
What is oxygen cycle in biology?
Oxygen cycle refers to the movement of oxygen through the atmosphere (air), biosphere (plants and animals) and the lithosphere (the Earth's crust). The oxygen cycle demonstrates how free oxygen is made available in each of these regions, as well as how it is used.
What are 2 steps of photosynthesis?
The stages of photosynthesis There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.
What are the two stages of photosynthesis called?
While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions.
What are the 2 stages of photosynthesis?
While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions.
What are the two things needed for cellular respiration?
Glucose molecules and oxygen are the two main raw materials involved in the cellular respiration process. Cellular respiration is a set of metabolic reactions, which occurs inside the living cells.
Why is there 2 phases of photosynthesis?
In the second stage, the Calvin cycle takes place. Here, carbon dioxide is used to produce glucose. It is a continuously occurring cycle, hence the name. In addition to the carbon dioxide, the energy that is provisionally accumulated in the ATP and NADPH is also used to generate glucose – the sugar.
What are the 2 stages of photosynthesis and where do they occur?
Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2.
Which of the following processes requires oxygen?
Key Terms
| Term | Meaning |
|---|---|
| Aerobic | Process that requires oxygen |
| Anaerobic | Process that does not require oxygen |
| Fermentation | An anaerobic pathway for breaking down glucose |
What 2 materials are produced during photosynthesis?
The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.
What are the 2 phases of photosynthesis called?
There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle. Requires sunlight? Schematic of the light-dependent reactions and Calvin cycle and how they're connected. The light-dependent reactions take place in the thylakoid membrane.
What is the 2 stage of photosynthesis?
The second stage of photosynthesis is called the Calvin cycle. Photosynthesis takes place in two stages – the first phase is where the light reactions or the light-dependant reactions occur. In the second stage, the light-independent reaction takes place, the Calvin cycle.
What are the 2 main steps of photosynthesis?
While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions.
What are the 2 types of reactions in photosynthesis?
There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.
Which of the following plays a very important role in the oxygen cycle?
Plants plays a very important role in the oxygen cycle as they are the only living things on earth which take in carbon dioxide and gives out oxygen which are essential for breathing.
Which set of processes occurs when there is a supply of oxygen?
Aerobic respiration, which takes place in the presence of oxygen, evolved after oxygen was added to Earth's atmosphere. This type of respiration is useful today because the atmosphere is now 21% oxygen.
What are the two most important products that result from photosynthesis?
Specifically, plants use energy from sunlight to react carbon dioxide and water to produce sugar (glucose) and oxygen.
