In terms of the source of their carbon, plants are \( \square \), and animals are \( \square \).

Plants are autotrophs, meaning they produce their own carbon through the process of photosynthesis, using sunlight, water, and carbon dioxide from the air. They convert these ingredients into glucose, which serves as their energy source! Meanwhile, animals are heterotrophs, relying on consuming other organisms—be it plants or other animals—for their carbon and energy needs. This fundamental difference creates unique roles in ecosystems, with plants providing the primary energy source for nearly all life forms. When considering carbon in the context of climate change, understanding these roles becomes essential. Plants absorb carbon dioxide, acting as natural carbon sinks, while animals release carbon dioxide when they breathe or decompose. Enhancing plant populations and reducing deforestation are pivotal steps in mitigating climate change, showcasing the impact of both carbon sources on our planet's health!
