C) Decreasing the Temperature

The correct option is this: DECREASING THE TEMPERATURE.

During the process of chemical reaction, the reacting molecules typically move about randomly in the reacting vessels colliding with one another and with the wall of the container. The rate of movement of the reacting particles can be reduced by decreasing the temperature of the reaction. If the temperature is reduced, the particles will lose kinetic energy and thus, they will move more slowly and collide less often with one another.

Rosa drew a flow chart of the carbon cycle.
Lisa [10]

The correct Answer is A.

The Flow chart of the Carbon Cycle, will look as follows:

1. Carbon dioxide in the atmosphere.

2. Producers undergo photosynthesis (in this process plants among other producers like algae, use CO2 to produce energy).

3. Consumers eat producers (a primary level of consumer like a rabbit eats the producers or plants).

4. Decomposers return Carbon to the soil and release waste.

And the  cycle continues again, by going back to step 1.
