Definition of carbon cycle The carbon cycle is the circulation and transformation of carbon back and forth between living things and the environment.

When we burn fossil fuels we are adding more carbon dioxide to the air. Cellular respiration is breaking down food to yield energy which creates carbon dioxide. Plants use carbon dioxide, water and sunlight to create food (sugar). This sugar contains carbon – C6 H12 O6 Herbivores eat plants- sugar (carbon) is passed from plants to animals.

Photosynthesis and Cellular Respiration Photosynthesis recycles carbon by taking the carbon dioxide out of the air. It then uses water and sun light to create sugar. Breaking down sugar from photosynthesis to yield energy which creates carbon dioxide.

What is a fossil fuel and how does burning it influence the carbon cycle Fossil fuels are hydrocarbons, primarily coal, fuel, oil or natural gas, formed from the remains of dead plants and animals. When we burn fossil fuels, the carbon is released into the atmosphere as carbon dioxide.

How do fossil fuels influence climate? Burning fossil fuels like coal, oil and natural gas releases carbon that has been stored away for millions of years. It is this extra carbon dioxide that is causing climate change.

Carbon cycle and ocean Carbon dioxide comes from the atmosphere and dissolve in the surface of water that’s in the ocean. It is using up the carbon by biological and chemical that allow more carbon dioxide to enter the water from the atmosphere. https://www.youtube.com/watch?v =HrIr3xDhQ0E

True/False questions Carbon can’t get from the deep ocean soils on the land. There is different types of carbon on land. True / False Ocean life can survive without carbon True / False

Short answer What is a fossil fuel and give an example? How do fossil fuels affect our climate?

Long answer What is the definition of carbon cycle? What is cellular Respiration?
