Carbon Dioxide
Photosynthesis produces oxygen as a waste product.
Plants let out gases. This gas is called oxgen which animals and humans need to breathe so we can live. Animals let out a gas called carbon dioxide and the plants need to take in the carbon dioxide to live.
plants during photosynthesis take in carbon dioxide and give out oxygen while animals during respiration breathe in oxygen and breathe out carbon dioxide making a complete continuous cycle.
oxygen
Both plants and animals use oxygen in their body chemistry. Animals exhale carbon dioxide. Plants give off mostly oxygen during the daylight hours when photosynthesis occurs, but excrete carbon dioxide at night.
Photosynthesis produces oxygen as a waste product.
Plants use photosynthesis to make oxygen and glucose. Without plants, all animals including humans would die from no food and no oxygen to breathe.
they provide oxygen for humans and animals to breathe by photosynthesis, the process in which plants use carbon dioxide and give off oxygen
Photosynthesis
Animals do not use up all the oxygen in the atmosphere because plants produce oxygen. When they breathe, plants inhale carbon dioxide (which is what animals breathe out) and exhale oxygen (which is what animals breathe in).
Plants let out gases. This gas is called oxgen which animals and humans need to breathe so we can live. Animals let out a gas called carbon dioxide and the plants need to take in the carbon dioxide to live.
Photosynthesis is where plants get nutrients from the sun. This is important for man and animals because, if the plants couldn't use photosynthesis, they would die off. If all the plants die off, then man and animals couldn't get nutrients fom the plants, therefore making the process of photosynthesis needed by both plants and animals.
oxygen
plants during photosynthesis take in carbon dioxide and give out oxygen while animals during respiration breathe in oxygen and breathe out carbon dioxide making a complete continuous cycle.
Animals don't use photosynthesis. Only plants do.Animals obtain energy and carbon from other organisms. Plants get from light and CO2
Carbon Dioxide is absorbed by plants for use in photosynthesis to make sugars. During the process of photosynthesis, some oxygen is made as a byproduct. This oxygen is then inhaled by animals. Animals exchange oxygen in the air for carbon dioxide. Then the cycle starts over again.
Plants need us because when we exhale we breathe out carbon dioxide which plants need for a process called "photosynthesis".
