Carbon Cycle

What are the steps for the Carbon Cycle? Why is it important for the ecosystem?

Death and decomposition create carbon. ANimals release carbon when they breathe. Plants use the carbon dioxide to build organic molecules. Many animals use the oxygen the plants release to break down organic materials and then they release CO2. This process is called respiration. Carbon is also released by combustion or the burning of a substance.

The carbon cycle is imporant! first death and decomposition make the carbon. The plants use the carbon that the animals produce. Animals use the oxygent o break down organic matter and then they release co2. This is called resiration. Carbon can be prdocuded other ways too like combustion.

The carbon cycle is made up of death and decomposition release carbon. Animals also release carbon when the breathe.The plants take in the carbon that the animals create. When burning a fossil fuels carbon is released called combustion.

the Carbon Cycle the circulation of carbon atoms in the biosphere as a result of photosynthetic conversion of carbon dioxide into complex organic compounds by plants. these plants are consumed by other organisms. the carbon returns to the atmosphere in the form of carbon dioxide as a result of respiration, decay by fungi, bacteria, etc., and combustion of fossil fuels.

Alright the death creates carbon from the dead tissue. Animals also release carbon they breathe. Plants use the CO2 to create oxygen. That process is called respiration. Then there is combustion when you burn things

Carbon is made from dying and breathing animals. the carbon from that is used for plants. EVERYTHING NEEDS CARBON!!!!!!!!!!!!!!

Carbon Cycle: decomposition and death make carbon. we give off carbon when we breath (so do animals) plants use that carbon that we give off to make food. also released through combustion. (the burning of a substance)

In the carbon cycle, plants use the carbon dioxide in the air during photosynthesis. Plants then release oxygen for people and animals to use. We then use to break down organic molecules and realse CO2. Now the plants can use it. Carbon can also go into the air through combustion or dead things. IT is important because we need oxygen to live, and plants need CO2 to live.

Death and decomposition make carbon. Animals release carbon and plants use the co2. Animals breath in the oxygen and then release co2. That is called respiration. Carbon is also released by burning things.

The carbon cycle is when plants and animals die they give off carbon nd when we take in oxygen we also realese carbon and then the plants take in carbon and turn it into oxygen.

The carbon system starts with decomposition from dying and decaying organisms. Animals will release carbon when they die and it will go into the atmostphere. The plants use this carbon to produce oxygen for us to live on. When we get the oxygen that the plants made then we will breathe out carbon and further supply the many plants that are in need of carbon. So we both supply each other with basic needs.

The carbon cycle is kinda important. The first step of the carbon cycle is an organism dies. The plants use the carbon that the dead organism produces. Animals use the oxygen to break down organic matter and then it will release co2, this process is called resiration. Carbon can be produced other ways also, such as cumbustion, which is the burning of a substance.
