Light reaches organisms in the photic zone, where microscopic Phytoplankton and multicellular algae provide food for the animal community. Light levels in aphotic zone are too low to support photosynthesis. The seafloor is called the Benthic realm. Fishes and marine mammals swim in open water known as the Pelagic realm. A distinctive Biome called an Estuary is found where a freshwater stream or river merges with the ocean.

Photic zone is the surface layer of the ocean that receives sunlight, which means it permits photosynthesis by plants and phytoplankton. In aphotic zone , there is no light, therefore the phytoplankton and algae can not grow and undertake photosynthesis, the carbon dioxide is accumulated, there is less Oxygen and the pH is lower than in the photic zone.

Phantasy [73]

Answer:

unicellular - both prokaryotes and eukaryotes

contain mitochondrion - eukaryotes only

are generally less than 2 pm - Prokaryotes only

multicellular - eukaryotes only

lack membrane-bound organelles - prokaryotes only

Explanation:

Prokaryotes are generally unicellular, that is, they are made up of single cells only. However, there are unicellular and multicellular eukaryotes with some eukaryotes like humans and advanced plants having as many as millions of cells.

Prokaryotes generally lack nucleus and other membrane-bound organelles such as chloroplast and mitochondrion. Eukaryotes on the other hand have nucleus and membrane-bound organelles such as mitochondrion and chloroplast.

When it comes to size, prokaryotes are generally small and microscopic while eukaryotes consist of both microscopic and macroscopic cells or organisms. However, prokaryotes are generally smaller than microscopic eukaryotes.
