Light energy IS required for Photosynthesis
The initial activation energy for the process of photosynthesis is the energy required to initiate the conversion of light energy into chemical energy. This energy is used to break the bonds in the reactants and start the photosynthetic reactions.
Photosynthesis is not required for animals to obtain energy from food, as it is the process by which plants and some other organisms convert light energy into chemical energy stored in glucose. Animals must digest and metabolize food, but they do not perform photosynthesis.
Radiation is the process of heat transfer where material medium is not required. Energy is transferred through electromagnetic waves such as infrared radiation or light. This process can occur in a vacuum as well.
Energy is required in the melting process because high is needed to melt something
Chloroplasts convert light energy into chemical energy. The energy of light captured by pigment molecules, called chlorophylls, in chloroplasts is used to generate high-energy electrons with great reducing potential.
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
Light energy from sun is used. Chlorophylls capture light energy

it is only needed for photosynthesis as we humans do not get our energy from light ( think about it we still breath when it is dark don't we)
Photosynthesis is the process that uses light energy to make new substances that have chemical energy.
photosynthesis converts light energy into chemical energy (ATP)
Photosynthesis is the process in plants that converts light energy into chemical energy. This occurs in chloroplasts, where chlorophyll absorbs light and uses it to convert carbon dioxide and water into glucose and oxygen.
