Biodiversity: Carbon Dioxide 🌳 GCSE Bio...

Seneca Learning
About this episode

This episode explains the role of carbon dioxide in the environment. 

It highlights that carbon dioxide is a greenhouse gas and discusses both its natural removal and release. 

Photosynthesis by plants and algae naturally removes carbon dioxide from the atmosphere while respiration is a natural source of release. 

Human activities, such as burning fossil fuels, also contribute to carbon dioxide emissions. 

The episode concludes by noting the greenhouse effect is a natural insulation in the atmosphere.
