Where do plants get most of the energy they need to live and grow?
A
water
B
soil
C
air
D
sunlight
Explanation: 

Detailed explanation-1: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.

Detailed explanation-2: -In most plants, the leaves are the main food factories. They capture the sun’s energy with the help of chlorophyll in the leaf cells. The chlorophyll traps and packages the energy from the light of the sun in a process called photosynthesis. Leaves usually have a large surface so they can collect the most sunlight.

Detailed explanation-3: -During photosynthesis, plants harness the energy in sunlight and use it to fuse water (absorbed from the soil) and carbon dioxide (absorbed from the air) to form simple sugars, releasing oxygen as a by-product.
