Detailed explanation-1: -Brodribb and Feild argue that more photosynthesis meant more carbon for growth. And that would have given the angiosperms the energy to push competitors like conifers out of the canopy around 150 million years ago, making angiosperms the most productive group of land plants in the world.

Detailed explanation-2: -We breathe in oxygen and breathe out CO2. Plants do the opposite-they breathe in CO2 and breathe out oxygen during photosynthesis. Because angiosperms photosynthesize so much, they are some of the best oxygen makers around.

Detailed explanation-3: -Angiosperms are highly variable in form. They include herbs, shrubs, trees, vines, and succulents. They occur in a great many habitats, from forests, grasslands, and deserts, to aquatic and marine environments.

Detailed explanation-4: -Angiosperm Examples Grains, including rice, corn, and wheat, are also examples of Angiosperm. In these plants, the pollination process is carried out by the wind. Other examples of Angiosperms include roses, lilies, Broccoli, kale, Petunias, Eggplant, Tomato, Peppers and sugarcanes.
