When running, a person takes deep breaths in order to get which gas from the air?
Oxygen
What are the products of cellular respiration?
Carbon dioxide, water, and ATP energy
What is the process that combines water, carbon dioxide, and light to make sugar?
Photosynthesis
What gas is produced by plants during photosynthesis that animals use for respiration?
Oxygen
A large number of plants and trees were destroyed by a forest fire. What will happen in the area; oxygen will increase or decrease??
The amount of oxygen produced will decrease
Through what process do ALL living things add carbon to the atmosphere; eating plants, or decay?
Decay
The energy that animals need for their life functions is released when their cells...; break down carbon-based molecules, or, absorb water from the environment?
break down carbon-based molecules
What is the process by which animals use oxygen and food to make energy and carbon dioxide?
Respiration
What is the movement of carbon dioxide and oxygen on Earth by the processes of respiration and photosynthesis?
The carbon dioxide-oxygen cycle
What gas is produced by animals during respiration that plants use for photosynthesis?
Carbon dioxide
Which process is happening when carbon dioxide is moved from animals to the atmosphere?
Respiration
Which process removes carbon from the atmosphere; decay or photosynthesis?
Photosynthesis
What do animals breathe out that plants absorb?
Carbon dioxide
What process is happening when carbon dioxide is moved from the atmosphere to plants?
Photosynthesis
What gas do animals add to the atmosphere when they breathe?
Carbon dioxide
What is the process where plants use sunlight, water, and carbon dioxide to produce sugar and release oxygen?
Photosynthesis
What would happen to animals in an area if all the plants were removed? Why?
Animals would perish because the amount of oxygen would decrease
A large number of trees in the rainforest are cut down. What effect could this have on the carbon dioxide-oxygen cycle if the removal of so many plants and trees continues; carbon dioxide will increase or water vapor will increase?
Carbon dioxide will increase
