The cycling of carbon dioxide in photosynthesis and cellular respiration are main components of the carbon cycle. Carbon is also returned to the atmosphere by the burning of organic matter (combustion) and fossil fuels and decomposition of organic matter.
What is the primary process that returns carbon to the atmosphere?
Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle.
How does carbon dioxide enter the atmosphere quizlet?
Carbon dioxide is released into the atmosphere through respiration of plants, animals and microorganisms. It is also released by combustion of wood and fossil fuels (oil, coal, gas). Burning of fossil fuels is gradually increasing co2 levels in atmosphere.
How is carbon dioxide returned to the atmosphere Brainly?
Answer. Organism return carbon dioxide to the atmosphere by respiration.
Where does carbon dioxide come from?
Carbon dioxide (CO2) comes from both natural sources (including volcanoes, the breath of animals and plant decay) and human sources (primarily the burning of fossils fuels like coal, oil and natural gas to generate energy).
Which of the following is one way that carbon enters the atmosphere quizlet?
Terms in this set (7)
Carbon enters the atmosphere as Carbon Dioxide from Respiration and Combustion.
How does carbon in the form of carbon dioxide enter the oceans quizlet?
How does carbon get into the oceans? Carbon dissolves and combines with calcium into shells of animals , shells decay make limestone
carbon released from limestone back to air.
How does carbon leave the hydrosphere and enter the atmosphere?
Natural Carbon Releases into the Atmosphere
Gases containing carbon move between the ocean’s surface and the atmosphere through a process called diffusion.
How does a primary consumer get carbon?
Primary consumers take in carbon from carbon dioxide from the atmosphere and fix it in compounds called carbohydrates.
What is a primary producer in the carbon cycle?
The primary producers, largely comprised of plants, form the foundation of the food chain and use solar radiation to convert carbon dioxide and water into carbohydrates via photosynthesis.
What is the primary function of the carbon cycle quizlet?
The carbon cycle is one of the main cycles in nature, the carbon cycle produces nutrients and energy in plants for animal consumption. The cycle also is responsible for all oxygen production.
Which of the following is not one of the ways that carbon enters the atmosphere?
Answer and Explanation: The answer is c. photosynthesis. The forest fires, respiration, and burning of fossil fuels are processes that emit or produce carbon gases such as…
How does carbon exit the biosphere?
Large quantities of carbon pass between the atmosphere and biosphere on short time-scales: the removal of atmospheric carbon occurs during photosynthesis, following the reaction CO2 + H2O = CH2O + O2, while most carbon leaves the biosphere through respiration, a reversal of the previous reaction in which an amount of …
How does carbon exit the lithosphere?
Carbon moves from the lithosphere to the atmosphere via volcanism or volcano eruption. When volcanos erupt, magma exits the earth’s mantel and lithosphere and trapped carbon dioxide gas is also released out.
How does atmospheric carbon dioxide get into the ocean?
The ocean takes up carbon dioxide through photosynthesis by plant-like organisms (phytoplankton), as well as by simple chemistry: carbon dioxide dissolves in water.
How does carbon dioxide get absorbed into the ocean?
Explanation: The ocean can absorb carbon dioxide ( CO2 ) in 2 ways: diffusion from the atmosphere and through photosynthesis in plankton and algae.
What is the primary way in which carbon is delivered to the seafloor?
Sinking shells bring carbon down to the deep ocean
Many shells dissolve before reaching the seafloor sediments, a process that releases CO2into deep ocean currents. Shells that do not dissolve build up slowly on the sea floor forming calcium carbonate (CaCO3) sediments.
How does carbon get from the geosphere to the atmosphere?
Several processes move carbon from the geosphere to the atmosphere. Volcanic eruptions release carbon dioxide from molten rock beneath the earth’s surface. The production of cement that’s used for homes, skyscrapers, streets and other hardscapes around the world releases an enormous amount of carbon dioxide.
How is carbon exchanged between geosphere and hydrosphere?
Carbon is removed from the atmosphere by photosynthesis, dissolving in ocean water, and weathering of rocks. From there carbon is exchanged between the biosphere, hydrosphere, geosphere, and back to the atmosphere in a variety of ways, including the burning of fossil fuels.
Do primary consumers give off carbon dioxide?
Primary consumers eat producers. They release some carbon dioxide through cellular respiration. This transfer of carbon continues throughout the food chain.
Do secondary consumers release carbon dioxide?
Do secondary consumers release carbon dioxide? Secondary consumers eat producers respirate releasing energy in the body and carbon dioxide into the atmosphere. … As they break these down they respirate returning carbon dioxide to the atmosphere and nutrients to the soil.
Which is a primary consumer?
Primary consumers make up the second trophic level. They are also called herbivores. They eat primary producers—plants or algae—and nothing else. For example, a grasshopper living in the Everglades is a primary consumer.
