Well, many organisms would die. Plants need light so they would die out rather quickly. The surrounding area would warm up initially due to the green house effect, but would eventually cool down.
The answer is C. Mollusks. Hope this helps. :)
The type of cellular transport that does not involve the flow of particles from an area of high concentration to an area of low concentration is called the active transport.
Cellular transport of ions, gases, nutrients, waste substances and other biomolecules is of two types namely, the passive transport and the active transport. Passive transport is the movement of substances along their concentration gradient from a region of their higher concentration to the region of their lower concentration which does not require energy.
Active transport is the movement of substances against their concentration gradient from a region of their lower concentration to the region of their higher concentration. It uses energy in the form of Adenosine triphosphate (ATP). The best examples being the sodium-potassium pump in the cells and the uptake of glucose in the intestines.
Lynn Margulis and Karlene Schwartz, in their book The Five Kingdoms (W.H. Freeman, 1998), struggled heroically to justify the Protista (they preferred the term Protoctista) kingdom. "Undulipodia (aka flagella) were present in common ancestors to all the phyla, even before mitochondria, given that the anaerobic archaeprotists bear them." However, a sentence later they admit that "in some phyla, all members bear undulipodia, in other phyla, they are absent..." It seems a shaky foundation on which to build a kingdom. All human cells are fathered ultimately by sperm, which bear undulipodia, but no one has suggested that humans are therefore protists.
