Answer:
Uses of plants:-
The importance of plants to humans and just about all other life on Earth is staggering. Life as we know it would not be possible without plants.
➔Plants supply food to nearly all terrestrial organisms, including humans. We eat either plants or other organisms that eat plants.
➔Plants maintain the atmosphere. They produce oxygen and absorb carbon dioxide during photosynthesis.
➔Oxygen is essential for cellular respiration for all aerobic organisms. It also maintains the ozone layer that helps protect Earth’s life from damaging UV radiation.
➔Removal of carbon dioxide from the atmosphere reduces the greenhouse effect and global warming.
Plants recycle matter in biogeochemical cycles.
➔For example, through transpiration, plants move enormous amounts of water from the soil to the atmosphere.
➔Plants such as peas host bacteria that fix nitrogen. This makes nitrogen available to all plants, which pass it on to consumers.
