What is not dependent on sunlight as a source of energy?

A. Benthic Zone
B. Pelagic Zone
C. Neritic Zone
D. Taiga
E. Tundra

I think it's A, B, or C. Is it?

To determine what is not dependent on sunlight as a source of energy among the given options, we need to understand the characteristics of each option.

A. The benthic zone refers to the ocean floor, where sunlight does not penetrate. Therefore, organisms in the benthic zone rely on alternative sources of energy, such as chemosynthesis, which involves using minerals and chemicals rather than sunlight.

B. The pelagic zone refers to the open ocean, where sunlight can penetrate the water. Organisms in the pelagic zone, such as phytoplankton, rely on sunlight for photosynthesis, making them dependent on sunlight as an energy source.

C. The neritic zone is the area of the ocean that extends from the shoreline to where sunlight can no longer reach the ocean floor. This zone includes coastal areas where sunlight is abundant, enabling photosynthesis to occur.

D. The taiga, also known as a boreal forest, is a biome characterized by coniferous forests. The trees in the taiga rely on photosynthesis and, thus, depend on sunlight as an energy source.

E. The tundra is a biome characterized by low temperatures and a short growing season. While some vegetation can grow in the tundra, it is limited and relies on sunlight for photosynthesis.

Based on this information, options A (Benthic Zone) and D (Taiga) are not dependent on sunlight as a direct source of energy. Therefore, the correct answer is either A or D.
