Question
Life would be impossible without plants. Explain, how?

Answer

All green plants are producers. They make food by the process of photosynthesis using water $\mathrm{CO}_2$ and sunlight. All forms of animals depend on plants for food. So, if there no plants, no food will be there. Plants are give oxygen also during photosynthesis, and there would be no oxygen in absence of plant. These two basic needs make plants important for us and we cannot think of life without plants.
