# 155 Summary of Human and Ecosystem

CO₂ and methane are greenhouse gases, trapping outgoing long wavelength radiation in the atmosphere and warming the Earth. Increased concentrations of these gases are causing global warming.

# 147 Summary of Ecosystem

Energy enters ecosystems in sunlight. Producers (photosynthetic plants) capture some of this energy and transfer it to organic substances such as carbohydrates. Consumers (animals and fungi) gets their energy by eating producers or other consumers.
