How do most Heterotrophs directly contribute to the carbon cycle?
Heterotrophs acquire the high-energy carbon compounds from the autotrophs by consuming them, and breaking them down by respiration to obtain cellular energy, such as ATP. Gas exchange through the atmosphere and water is one way that the carbon cycle connects all living organisms on Earth.
Which path through the carbon cycle is possible?
The best answer is C – plant, animal, atmosphere. During daylight hours, plants capture carbon dioxide from the atmosphere and use it to make carbohydrates which is stored as starch in the plant.
What three processes release carbon dioxide into the environment?
Processes or regions that predominately produce atmospheric carbon dioxide are called sources. Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt.
What would happen if photosynthesis and cellular respiration did not perform their roles in the carbon cycle?
If cellular respiration and photosynthesis stops performing their role in carbon cycle all the plants and animals will end up dying. This is because they are dependent on the carbon cycle for survival.
What is the role of carbon in cellular respiration?
During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons.
Where does the carbon come from in cellular respiration?
The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat. The carbohydrates, fat and proteins we consume and digest are eventually converted by a number of different biochemical pathways in the body to glucose (C6H12O6).
How much CO2 is produced in glycolysis?
six CO
How does cellular respiration change the amount of carbon dioxide in abiotic matter?
As organisms release energy during cellular respiration, carbon dioxide is produced from the carbon in energy storage molecules. Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall.
Do consumers give off or take in carbon dioxide?
The consumers give off carbondioxide, which is essential for production of food by the process of photosynthesis. The carbon dioxide is utilised for the syjnthesis of simple monosaccharide i.e., glucose.
Does dead matter release carbon dioxide?
In the carbon cycle, decomposers break down dead material from plants and other organisms and release carbon dioxide into the atmosphere, where it’s available to plants for photosynthesis. After death, decomposition releases carbon into the air, soil and water.
What causes carbon dioxide to decrease in the air?
Carbon dioxide levels decreased because of processes that included: dissolving in the oceans. use by plants for photosynthesis. formation of fossil fuels as plants died and their carbon compounds became locked up underground.
