If CO${}_2$ is removed totally from the biosphere, which organisms will be affected first ?

Secondary consumers are organisms, primarily animals, which eat primary consumers. Through photosynthesis (the process by which plants captures the sun's energy and uses it to grow), plants take carbon dioxide out of the atmosphere and release oxygen. The carbon dioxide is converted into carbon compounds that make up the body of the plant, which are stored in both the aboveground parts of the plants (shoots and leaves), and the belowground parts (roots). In the next step, animals eat the plants, breath in the oxygen, and exhale carbon dioxide. The carbon dioxide created by animals is then available for plants to use in photosynthesis. Carbon stored in plants that are not eaten by animals eventually decomposes after the plants die, and is either released into the atmosphere or stored in the soil. Therefore, If CO${}_2$ is removed totally from the biosphere; secondary consumers will be affected first.
