Detailed explanation-1: -Answer. Explanation: In photosynthesis, plants take in carbon dioxide to make glucose and oxygen. If plants are decreased, there won’t be enough plants to take in CO2, therefore CO2 will increase.

Detailed explanation-2: -Plant productivity supports wildlife and serves as the basis of a multitude of food chains. The decline of plants means there will be less food, which can further lead to declines in animal populations.

Detailed explanation-3: -A new study involving ANU and international collaborators has found plants release more carbon dioxide into the atmosphere through respiration than expected. Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration.

Detailed explanation-4: -Because plants take up carbon dioxide from the atmosphere and convert it into food, forests and other similar ecosystems are considered to be some of the planet’s most important carbon sinks.

Detailed explanation-5: -Carbon dioxide in the atmosphere warms the planet, causing climate change. Human activities have raised the atmosphere’s carbon dioxide content by 50% in less than 200 years.
