a - Euphotic Zone
b - Littoral Zone
c - Benthic Zone
d - Limnetic Zone

Answer 1

The darker zone in lakes where light penetration is negligible is called the benthic zone

Answer 2

The correct answer is OPTION C: Benthic Zone.

• The benthic zone is the lowest ecological zone in a body of water, and it is usually made up of seafloor sediments.
• These sediments are critical in providing nutrients to benthic zone species.
• Many organisms found in the benthic zone are not found elsewhere in the water column, particularly in the deep ocean.
• Methane leaks and hydrothermal vents are two habitats found in the benthic zone.
• Furthermore, all organic material deposited in the benthic zone comes from the ocean's higher layers.
