Animals get carbon by eating plants or by eating other animals.

so the correct answer would be C

The lion eats an herbivore that ate the grass

Plants use carbon dioxide for photosynthesis. By doing so, they remove inorganic carbon from the atmosphere and incorporate it into the plants’ tissues in the form of organic carbon (sugar and starch).

Carbon is returned to an inorganic state in a number of ways. As an animal breathes (respires), it exhales carbon dioxide, returning it back to the atmosphere. When an animal or plant dies, it is broken down by bacteria and fungi and again the carbon is released (this process is called decomposition).

Sometimes, instead of completely decomposing, a plant or animal may be fossilised, leading to its carbon being stored in a rock. After millions of years and under the right conditions, these fossils may turn into fossil fuels (oil, coal and natural gas).

hope this helps!!
