Question

why does plants need carbon dioxide

Answer 1

Answer:

Green leaves use energy from sunlight through photosynthesis to chemically combine carbon dioxide drawn in from the air with water and nutrients tapped from the ground to produce sugars, which are the main source of food, fiber and fuel for life on Earth.

Answer 2

Plants need carbon dioxide for carrying out the process called photosysthesis

Explanation:

• Photosynthesis is the lungs of our planet. Plants use light and carbon dioxide to produce the sugars they need to grow, releasing oxygen in the process. Carbon dioxide is the primary source of nourishment for plants, hence increasing its levels immediately stimulates their photosynthetic rate.
• This boost in photosynthesis, known as the “carbon dioxide fertilization effect”, enhances growth in many of the Earth’s plant species, with the effects seen most clearly in crops and young trees, and less so in mature forests.
