Overall, an extremely low amount. Even plants do not have high primary productivity (amount of light energy converted to chemical energy) compared to the sun's total energy output. The sun's light is absorbed or reflected; a substantial amount is reflected. Even then, plants can only utilize certain wavelengths of light - while others cannot be used. All in all, only about 1% of all sunlight that comes into the Earths atmosphere is actually used in photosynthesis. But of that energy that is assimilated by plants, again, not all of it is going to be passed on to the next level -- primary consumers.
The green world hypothesis states that there will always be more "green" or plants than the herbivores or primary consumers can eat. These herbivores are held in check by a variety of reasons, but ultimately much of the biomass of the primary producers is never passed along. This contributes to a large chunk of the energy that is not passed to primary consumers. On average, only 10% of available energy within any trophic level is passed along to the next level (depending on the ecosystem and trophic structure). So we could say that of the 1% energy that the plants use in primary productivity, 10% of that is present in primary consumers. Or 0.1% of the sun's total energy intercepted by Earth goes to the world's primary consumers.
This percent is further reduced when you only account for small herbivores. There are many different types of primary consumers who might actually be present in a different trophic level, which is often the case with decomposers. The number of small herbivores varies within ecosystems, though in most, they do not comprise a large population.

How does plantae get their food?
they get it from the suns energy

hydrogen
Does fungi capture and use the suns energy?
No, it does not.
Is more energy lost from an ecosystem when a herbivore eats a plant or when a carnivore eats an animal?
More energy is lost by the Carnivore eating the Herbivore because of the 10% rule. When the Herbivore eats the plant, he gains 10% of the plants energy, but when the Carnivore eats the Herbivore, the Carnivore is getting 10% of the plants 10% from the Herbivore.
Why do plants cannot survive without sun's energy?
Plants use the suns energy to make energy in a process called photosynthesis. The suns energy is used to produce glucose which provides the energy that the plants need to survive through processes such as respiration and expiration.
How do people benefit from daylight saving time?
I Hear When It first Started It was To Get More From The suns Light To Use Less Energy For $$$$ Reasons...
How the rat in the food chain obtains energy in directly from the sun?
it doesn't get energy directly from the sun it gets the suns energy from whatever producers it eats and if its a carnivore than it eats herbivores and herbivores eat producers so the rat gets energy from the herbivore which gets energy from the sun.
