Final answer:
True, Lithoautotrophs indeed use inorganic nutrients for carbon and energy sources, which allows them to synthesize their own food through chemosynthesis even in the absence of sunlight.
Step-by-step explanation:
The statement that lithoautotrophs use inorganic nutrients for carbon and energy sources is true. Lithoautotrophs, a type of autotrophs, are organisms that can synthesize their own food from inorganic substances. They use inorganic carbon, specifically carbon dioxide (CO2), to create organic compounds through a process known as chemosynthesis.
This allows them to live in environments where sunlight, the energy source for photosynthesis, is not available. Unlike photoautotrophs that require sunlight to produce food, lithoautotrophs utilize inorganic molecules as a source of energy, and thereby play a crucial role in sustaining the base of certain ecosystems, particularly in dark environments like deep-sea vents where photosynthesis is not possible.
