{'biogradable wastes': [1, 0, 0, 0], 'useful substances': [2, 0, 0, 0], 'active substances': [1, 0, 0, 0], 'bacteria': [4, 1, 2, 3], 'nuclear proteins': [2, 0, 0, 0]}
Biodegradable wastes are materials that can be broken down and decomposed by living organisms. To convert these wastes into useful substances, we need the help of microorganisms such as bacteria. Bacteria play a crucial role in the decomposition process by breaking down organic matter into simpler forms. They secrete enzymes that break down complex molecules, turning them into organic compounds like carbon dioxide, methane, and water.
Nuclear proteins (option 1) are not involved in the decomposition of biodegradable waste. Radioactive substances (option 2) are hazardous and should not be used for waste conversion. Viruses (option 3) are not capable of breaking down organic matter.
Therefore, the correct answer is option 4: bacteria.
