The variation in beak type enables the different individuals in a population to feed on different food sources.
The shape of the beak is key to determining the primary food source of the bird. Certain birds species have specialized beaks, but within populations of those species, there is a variation in beak shape.
This gives the population the ability to respond to changes in the environment and availability of different food sources.
For example, if because of a dry period there is a shortage of fruit, some individuals in the population have the beaks that enable them to feed on other things, survive and leave offspring.

The answer is an energy of Sunlight.
In the process of photosynthesis, plants use the energy of Sunlight to convert water and carbon dioxide into glucose (which is a sugar) and oxygen (which is a byproduct). Pigment chlorophyll in the leaves of green plants absorbs sunlight and convert it into the chemical energy in the form of ATP or NADPH which is then used for conversion of carbon dioxide into carbohydrate glucose.
