Plants use carbon dioxide during photosynthesis to make glucose, their primary source of energy. Carbon dioxide is also a key building block for plant growth as it is incorporated into carbohydrates, proteins, and other organic compounds through photosynthesis.

Carbon dioxide is broken down through photosynthesis and reformed (with the addition of oxygen and hydrogen) to form glucose.

Carbon dioxide is absorbed from the environment through the stomata located on the underside of the leaves.

Plants use CO2 in the process of making glucose in cellular respiration. Carbon dioxide is combined with water to create glucose, using the energy from light to power the reaction.

This is the chemical reaction that occurs in the chloroplasts, where chlorophyll molecules become excited by light, releasing an electron in an electron transport chain which is used to make glucose from the raw materials, CO2 and H2O:

6CO2 + 6 H2O + light=C6H12O6 +6O2

Animals don't use CO2. It is a waste product from cellular respiration and it must be excreted by breathing it out through the lungs. The upside is that animals put more CO2 into the atmosphere which is taken in by green plants to make food (glucose), and plants put out O2 as waste, replenishing the atmosphere with oxygen for animals to breathe.

Cellular respiration is essentially the opposite of photosynthesis, and this is the reaction:

C6H12O6=6H2O + 6CO2 + 36 ATP (used by cells for chemical energy)

It is perfect system. Plants use the CO2 waste gas from animal respiration to make glucose for chemical energy for cells and they put out oxygen into the atmosphere. Oxygen is taken in by animals, used to break down glucose to make ATP for energy for cellular processes, and giving out CO2 which plants take in for photosynthesis.

they use it when the CO2 goes in they let go and soon for water too

How do plants and animals help each other in exchange of gases in atmosphere?

During the process of photosynthesis release oxygen and animals (we) inhale oxygen and release carbondioxide. This is how plants and animals depend on each other by symbiosys. Hope that helps...


What do animals to give off that plants need?

Animals give off carbon dioxide, which is essential for photosynthesis in plants. Plants use carbon dioxide, along with sunlight and water, to produce oxygen and carbohydrates for energy. This exchange of gases between animals and plants helps to maintain the balance of oxygen and carbon dioxide in the environment.


In the test tube shown what is produced by the snail that is used by the plant?

The snail produces carbon dioxide through respiration, which the plant uses for photosynthesis. Photosynthesis is the process by which plants convert carbon dioxide into oxygen and glucose, which the plant can use for energy.


What is the process that is carried out in plants in which glucose is being produced?

Photosynthesis is the process. Plants use carbon dioxide in the air, as well as water and sunlight to make glucose and oxygen. The equation is Carbon Dioxide + Water => Glucose + Oxygen


What is it that Plants and animals take in and then give off?

Plants take in carbon dioxide and give off oxygen through the process of photosynthesis. Animals take in oxygen and give off carbon dioxide through the process of respiration. This exchange of gases is essential for the survival of both plants and animals.

How does carbon doxide help the plant?

Plants use carbon dioxide to convert into oxygen. Carbon dioxide (and water and sunlight) is needed for photosynthesis which is the process plants use to survive.


Do plants need carbon monoxide?

No, plants do not need carbon monoxide to survive. Carbon monoxide can actually be harmful to plants because it interferes with their ability to use carbon dioxide in photosynthesis.
