Answer 1

Answer:

as we all are aware of the fact that plants need light energy for photosynthesis

they prepare food through this process and hence we are dependent on them for food

Answer 2

As they rise through the atmosphere, they are intercepted by greenhouse gases, such as water vapor and carbon dioxide. Greenhouse gases trap the heat that reflects back up into the atmosphere. In this way, they act like the glass walls of a greenhouse. This greenhouse effect keeps the Earth warm enough to sustain life.
