Only the consumers will survive.

Detailed explanation-1: -Producers are the autotrophs which act as a source of food and energy for the consumers . If there where no produces, the consumers would die due to hunger and thus the other dependent trophic level will not survive and a time will come when they will be no life on earth.
Detailed explanation-2: -At each step up the food chain, only 10 percent of the energy is passed on to the next level, while approximately 90 percent of the energy is lost as heat.
Detailed explanation-3: -Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
Detailed explanation-4: -What will happen if the first source of energy will not be there? . A food chain shows the relationship between different organisms in the form of food. If the first source of energy, sunlight will not be there, then plants cannot produce food, and they will not grow and die.
Detailed explanation-5: -The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
