Look at the following diagram of the carbon cycle:

An image of carbon cycle is shown. The sun, a cloud, two trees, one on the left and the other on the right, an animal, lake, and a factory are shown in the image. An arrow is shown from the sun towards the left tree marked A. The sun is marked B. There is an arrow from the air above the clouds, marked C, towards the left tree. An arrow from a location close to the ground marked D points towards Dead Organisms, which is a label under the animal. An arrow marked E points from the right tree straight up to the clouds. An arrow marked F points from the animal straight up to the clouds. An arrow marked G points from the factory towards the air above the clouds, C. There is an arrow pointing from the air to the lake labeled Carbonates in Water, an arrow pointing down from dead organisms to Fossils and Fossil Fuels, and an arrow from Fossils to the factory.

Which of the following statements best describes the effects that removing the arrow pointing from G to C would have on the environment?

Removing this step prevents photosynthesis in the next step.
Removing this step decreases the amount of carbon in the soil.
Removing this step decreases the amount of carbon in the air.
Removing this step increases carbon storage in plants

Removing this step decreases the amount of carbon in the air.

The statement "Removing this step decreases the amount of carbon in the air" best describes the effects of removing the arrow pointing from G to C in the carbon cycle diagram. This arrow represents the carbon emissions released by the factory, which contribute to the amount of carbon in the air. By removing this step, there would be a decrease in the amount of carbon in the air.
