Question : Which ecosystem is the only one that does not thrive on solar energy?
Option 1: Marine organisms
Option 2: Phytoplanktons
Option 3: Deep-sea hydrothermal ecosystem
Option 4: Nitrogen-fixing bacteria
Correct Answer: Deep-sea hydrothermal ecosystem
Solution : The correct option is the Deep sea Hydrothermal Ecosystem .
In deep-sea hydrothermal vents, where sunlight doesn't penetrate, certain bacteria use the energy from the chemical reactions between minerals in the vent fluids and seawater to produce organic molecules. This process is called chemosynthesis. These bacteria form the base of the food chain in these ecosystems, and other organisms in the deep-sea hydrothermal ecosystem rely on them for sustenance.
