Answer:
1) carbon dioxide enters a plant and is used to make sugar; which is used to build plant tissue.
2) a primary consumer eats the plant. the plant's carbon enters the primary consumer.
3) carbon enters a high-level consumer when it eats the primary consumer. Some carbon exits as feces
4) fungi use the carbon that is found in the wolf's feces.
5) cellular respiration in fungi releases carbon dioxide to the atmosphere.
Explanation:
The above ilustration described a food chain involving the flow of carbon in the carbon cycle.
1) A food chain always begins with a PRODUCER e.g plants which undergoes photosynthesis to make its food (glucose sugar). Carbon in form of carbondioxide (CO2), which enters through the stomata of the plant is used in the photosynthetic process. Hence, photosynthesis removes carbon from the atmosphere.
2) An organism in the next TROPHIC LEVEL of the food chain called PRIMARY CONSUMER feeds on the plants. This causes the stored carbon in the plant to be transferred to the animal (primary consumer).
3) Another consumer higher than the primary consumer i.e. secondary and tertiary consumers eat the primary consumer, causing the carbon to be transferred to it. Some of this carbon is later released as feaces (undigested).
4) A set of organisms called DECOMPOSERS in ecology, which is the fungi in this case
begins to use the carbon source in the feaces as nutrients in order to grow.
5) Finally, the fungi undergoes cellular respiration which releases the carbon in form of carbondioxide (CO2) back into the atmosphere.
