Carbon dioxide.
u breathe out CO2 (carbon dioxide) which is absorbed by plants and used in photosynthesis to create oxygen for us
Animals breathe out carbon dioxide, which is used by plants during photosynthesis to produce oxygen and glucose. This exchange of gases between animals and plants is essential for the Earth's ecosystem.
Carbon dioxide (and water).
If you remember from biology, when people breathe out CO2, the plants breathe in that and blow out O2. That helps people breathe.Additional answerTechnically, plants don't breathe in CO2. They breathe in Oxygen. But they do also TAKE in CO2 and provided they are green plants and in sunlight they use the CO2 in photosynthesis and emit oxygen.CO2 is also used in fire extinguishers, and in some cooling chambers where it has been frozen (called dry ice) and used to keep the chamber or refrigerator cold.
Animals breathe oxygen and eat plants.
The last step in photosynthesis is the production of glucose or sugar molecules. This occurs in the stroma of the chloroplasts, where the energy from sunlight is used to convert carbon dioxide and water into glucose, which can then be used by the plant for energy.
An example of carbon moving from an inorganic compound to an organic compound in the carbon cycle is through the process of photosynthesis. During photosynthesis, plants take in carbon dioxide (an inorganic compound) from the atmosphere and convert it into glucose (an organic compound) through a series of chemical reactions using sunlight as an energy source.
Plants use carbon dioxide to aid in photosynthesis, and thus release oxygen for us to breathe in.
light (among many other things)
Chlorophyll is the key compound that enables photosynthesis in green plants. It is a pigment that absorbs light energy and converts it into chemical energy, which is used to produce glucose and oxygen from carbon dioxide and water.
Glucose is one important chemical substance used in photosynthesis. It is used for food, a sugar compound.
The compound needed for photosynthesis is carbon dioxide (CO2). During the light-dependent reactions of photosynthesis, CO2 is taken in by the plant through small openings called stomata on the leaves. This CO2 is then used in the Calvin cycle, also known as the light-independent reactions, to produce glucose and other organic compounds essential for plant growth and development.
