Which of the following is a conversion from light energy to chemical energy?
A
turning on a stove to heat dinner
B
turning on a lamp
C
making toast in a toaster
D
growing an apple tree
Explanation: 

Detailed explanation-1: -Photosynthesis is a process by which green plants and certain other organisms synthesise their own food i.e. transform sunlight energy into chemical energy with the help of chlorophyll, carbon dioxide and water.

Detailed explanation-2: -Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars.

Detailed explanation-3: -The energy found in apples is chemical potential energy. When it grows on a tree, the energy found in the apple is potential energy, and there is kinetic energy and heat energy involved when it hits the ground.

Detailed explanation-4: -When an apple falls from the tree to the ground, its energy of position (stored as gravitational potential energy) is converted to kinetic energy, the energy of motion, as it falls. When the apple hits the ground, kinetic energy is transformed into heat energy.

Detailed explanation-5: -Plants creates chemical energy through photosynthesis.
