Describe the flow of matter in the carbon cycle - Middle School Life Science

Card 0 of 20

Question

Where is most carbon on Earth stored?

Answer

The answer is "in rocks and sediments"

The carbon cycle describes the flow of the element Carbon in ecosystems. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. Carbon in the air is absorbed by plants in photosynthesis, consumed by organisms who eat the plants, and then it is returned to the soil when animals die and their organic matter decomposes. The same process happens in oceans with aquatic plants as well. Carbon is also emitted from the burning of fossil fuels which are made from the organic material of organisms that died millions of years ago.

Question

Carbon is absorbed from the atmosphere through what process?

Answer

The answer is "photosynthesis."

The carbon cycle describes the flow of the element Carbon in ecosystems. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. Carbon in the air is absorbed by plants in photosynthesis, consumed by organisms who eat the plants, and then it is returned to the soil when animals die and their organic matter decomposes. The same process happens in oceans with aquatic plants as well. Carbon is also emitted from the burning of fossil fuels which are made from the organic material of organisms that died millions of years ago.

Question

Why are forests and areas where there are many plants referred to as "Carbon sinks"?

Answer

The answer is "because plants absorb carbon in photosynthesis"

The carbon cycle describes the flow of the element Carbon in ecosystems. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. Carbon in the air is absorbed by plants in photosynthesis, consumed by organisms who eat the plants, and then it is returned to the soil when animals die and their organic matter decomposes.

Question

Which of the following has the largest effect on the carbon cycle?

Answer

The answer is "human activities." The carbon cycle describes the flow of the element Carbon on Earth. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. Carbon in the air is absorbed by plants in photosynthesis, consumed by organisms who eat the plants, and then it is returned to the soil when animals die and their organic matter decomposes.

Question

How do heterotrophs acquire their carbon?

Answer

The answer is "from eating autotrophs"

Question

Which of the following answer choices best describes the 4 main components of the Carbon Cycle?

Answer

The answer is "Photosynthesis, Decomposition, Respiration and Combustion." The carbon cycle describes the flow of the element Carbon on Earth. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. Carbon in the air is absorbed by plants in photosynthesis, consumed by organisms who eat the plants, and then it is returned to the soil when animals die and their organic matter decomposes.

Question

Which of the following is NOT a part of the Carbon Cycle?

Answer

The answer is "Carbon moves from the atmosphere into space." The Carbon Cycle is a closed system that operates on Earth and while some Carbon may move between Earth and space, that is not related to our Carbon Cycle. The carbon cycle describes the flow of the element Carbon on Earth. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. Carbon in the air is absorbed by plants in photosynthesis, consumed by organisms who eat the plants, and then it is returned to the soil when animals die and their organic matter decomposes.
