Final answer:
The carbon cycle involves the transfer and transformation of carbon as it cycles through ecosystems. Carbon is exchanged between organisms and the environment through processes like cellular respiration and photosynthesis.
Step-by-step explanation:
The carbon cycle involves the transfer and transformation of carbon as it cycles through ecosystems. Carbon is exchanged between organisms and the environment through processes like cellular respiration and photosynthesis. Producers such as plants remove carbon dioxide from the atmosphere through photosynthesis, while consumers obtain carbon by consuming other organisms. Decomposers release carbon back into the environment when they break down organic matter. Human activities, such as burning fossil fuels, release large amounts of carbon dioxide into the atmosphere.
