Answer:
Answer:
Solar energy (from sun)
Explanation:
All living organisms including plants need energy for their life processes. Plants are autotrophic organisms i.e. they are capable of producing their own energy source (food). They do this through the process of photosynthesis, which is the process which allows plants to produce food in form of organic molecules (carbohydrate) that they use as fuel. Plants power this process of photosynthesis by absorbing energy from sunlight, a characteristic that makes them unique, since, they are the only organisms with this ability.
Plants possess green pigments called CHLOROPHYLL, contained in their chloroplast, which they use to absorb energy in form of light from the Sun.
