The aphotic zone contains no algae or phytoplankton, and its inhabitants are exclusively carnivorous animals or organisms that feed on sediment or detritus, all reliant on energy inputs from the euphotic zone.

Answer:
1. Plants are green due to presence of green pigment chlorophyll in their chloroplasts.
2. ATP is used to make organic sugars (glucose)
Explanation:
Chlorophyll pigments absorb the light in the blue and red regions and reflect all the green light. When the reflected green light reaches our eyes, the plants look green in color. The color of the object is determined by the color of the reflected light.
Splitting of water during the light-dependent phase of photosynthesis and electron transfer through cytochrome b6/f complex generates the proton concentration gradient which in turn drives the synthesis of ATP. Calvin cycle refers to the set of reactions that fix the atmospheric CO2 into organic sugars such as glucose. The ATP molecules formed during light reactions are used to drive the endergonic reactions of the Calvin cycle.
The cell would die. This is because mitochondria are essential for making energy that the cell can use, if the mitochondria stopped working this energy would not longer be available to the cell. If the cell does not have energy, it cannot perform vital functions like respiration.
