Question

The model shows part of how carbon is cycled between living organisms. The (bottom) green box in the model represents organisms that remove carbon dioxide from the atmosphere to recycle it. Which BEST describes these organisms? a producers that carry out photosynthesis to make carbon-rich sugars b bacteria that combine carbon dioxide with nitrogen to make nutrients c fungi that break down oxygen and release carbon dioxide in exchange d consumers that make energy by taking in carbon dioxide when they inhale

Answer 1

The best description for the organisms in the green box, which remove carbon dioxide from the atmosphere to recycle it, is:

**a. producers that carry out photosynthesis to make carbon-rich sugars.**

Producers, such as plants, algae, and some bacteria, use photosynthesis to convert carbon dioxide from the atmosphere into glucose and other carbon-rich compounds, effectively cycling carbon in the ecosystem.
