What group of organisms is the source of oxygen?
Plants are multicellular organisms that are capable of oxygen production. Is it estimated that there are approximately 422,000 known plant species.
What two processes take place during the oxygen cycle?
The two processes that take place during the oxygen cycle would be cellular respiration and photosynthesis. The oxygen cycle is also known as the carbon cycle.
A process by which nutrients increase in a lake while oxygen levels decrease as a result of human activity is known as?
Eutrophication
Do plants emit carbon dioxide?
Plants do produce carbon dioxide, however, the amount they produce is generally a net NEGATIVE amount. Plants, like all carbon based life forms known to date produce carbon dioxide as they use energy for biological work. This is part of the normal functioning of cells that they require oxygen in order to do this work, during which they are consuming oxygen and sugars, bonding carbon with oxygen in the process creating carbon dioxide. If they did not do this, they could not grow, and could not repair damage. HOWEVER, plants also take in carbon dioxide and use it combined with light energy in photosynthesis. This process separates the carbon and oxygen molecules, and the carbon is utilized in the preparation of stored energy ("food"). The oxygen molecules are released into the atmosphere. In a healthy plant through the bulk of its life, the plant produces more oxygen and removes more carbon dioxide than it uses oxygen and produces carbon dioxide. Exact amounts will vary based on available light, plant species, water, atmospheric condition and overall health of the plant. In >general< the more green you see on the plant, the more of the plant involved in photosynthesis and the more oxygen it produces. however, this does not tell you how much oxygen it uses (and thus how much carbon dioxide it produces). but in general, plants (and other chlorophyll laden life forms) consume more carbon dioxide than they create.
How did oxygen become a part of earth's atmosphere and what did this increase in oxygen levels allow?
The majority of oxygen in the atmosphere come from photosynthesis. Aquatic Cyanobacteria (blue green algae) were the first known organisms to use photosynthesis, before there were land plants. The by product of photosynthesis is oxygen. This increase in oxygen eventually allowed organisms to use respiration as a method of energy production. Thus it allowed for land animals.
What gas is released when plants respire throughout the day?
Oxygen, and it's known as "Photosynthesis" process But during the night, plants release carbon dioxide like a normal human
Do plants make or eat food?
plants create food during a process known as photosynthesis , this requires water , carbon dioxide and sunlight Photosynthesis creates glucose 9 which is the plants energy) and oxygen This is how plants help the environment because they use carbon dioxide and the oxygen is produced.
How do plants and animals primarily use the oxygen to convert their food?
oxygen is primarily used by all living things to breakdown food to energy in a process called oxidation. We get this oxygen by respiration process. Apart from this plants use oxygen to make their food using sunlight in presence of Chlorophyll. Ad also by exhaling..
How does oxygen get into earths atmosphere?
The process is very well-known in Biology called the Photosynthesis. It plays an role in plants because plants get it energy from sun.
How does earth get oxygen into it's atmosphere?

What did the green plants produce?
Green plants produce oxygen as a waste product. When plants store energy in the form of food, they use up carbon dioxide. This process is known as Photosynthesis.
What gas do plants release to the air?
Plants take in CO2 (carbon dioxide) and create and emit O2 (oxygen)Plants are an important part of the world, they help to keep us alive. The Best known gas released by plants is oxygen. They do also release carbon dioxide and water vapor.
What does it produce for living things?
The most common thing that produces something for living things is plants. Plants produce oxygen as a waste product of their food making process known as photosynthesis. Humans and animals need oxygen in order to breathe.
What is the process by which plants make food is?
The process in which plants make their food is known as photosynthesis.

Plants are multicellular organisms that are capable of oxygen production. Is it estimated that there are approximately 422,000 known plant species.
From where does most of the oxygen in the atmosphere come?
Most but perhaps not all began when tiny organisms known as cyanobacteria, or blue-green algae (in the seas and oceans) began conducting photosynthesis: using sunlight, water and carbon dioxide to produce carbohydrates and oxygen.In fact, all the plants on Earth incorporate symbiotic cyanobacteria (known as chloroplasts) to do their photosynthesis for them today.
