Final answer:
True. The aphotic zone in the deepest parts of the ocean lacks light but still supports colonies of life thanks to chemosynthetic bacteria.
Step-by-step explanation:
True. There are places on the deepest parts of the ocean where no light penetrates, known as the aphotic zone. Despite the absence of sunlight, colonies of life can still be found in this zone, thanks to chemosynthetic bacteria that use the energy from hydrogen sulfide and other minerals emitted from hydrothermal vents. These bacteria serve as the base of the food chain in the aphotic zone, supporting a variety of invertebrates and fishes.
