How does carbon get from animals to water?
Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.
What are the two ways animals get carbon?
Animals get carbon by eating plants or by eating other animals.
How does carbon return to the atmosphere from animals?
When animals eat food, they get carbon in the form of carbohydrates and proteins. The carbon combines with oxygen to form carbon dioxide (CO2) and is released back into the atmosphere as a waste product when animals breathe and exhale.
How is carbon dioxide returned to water?
The ocean takes up carbon dioxide through photosynthesis by plant-like organisms (phytoplankton), as well as by simple chemistry: carbon dioxide dissolves in water. It reacts with seawater, creating carbonic acid. In the center of the ocean, wind-driven currents bring cool waters and fresh carbonate to the surface.
How do animals get rid of carbon?
In animals, oxygen combines with food in the cells to produce energy for daily activity and then gives off carbon. The carbon combines with oxygen to form carbon dioxide (CO2) and is released back into the atmosphere as a waste product when animals breathe and exhale.
Does carbon stay in animals?
Carbon can be stored in a variety of reservoirs, including plants and animals, which is why they are considered carbon life forms.
What do organisms use carbon for in water?
Many organisms use carbon to make calcium carbonate, a building material of shells and skeletons. Other chemical processes create calcium carbonate in the water. The using up of carbon by biological and chemical processes allows more carbon dioxide to enter the water from the atmosphere. This opens in a new window.
How are living things moving carbon in the ocean?
Living things in the ocean move carbon from the atmosphere into surface waters then down into the deeper ocean and eventually into rocks. This action of organisms moving carbon in one direction is often called a biological pump.
What happens to carbon dioxide when organisms die?
This action of organisms moving carbon in one direction is often called a biological pump. matter or structural calcium carbonate. When organisms die, their dead cells, shells and other parts sink into deep water. Decay releases carbon dioxide into this deep water.
How does carbon move through the food chain?
Carbon moves from one storage reservoir to another through a variety of mechanisms. For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules.
