I think its sensitivity. Not quite sure tho
Distillation is the process of separation in which the volatile parts of a liquid mixture are separated by selective boiling and condensation. This process may lead to partial separation or complete separation. Distillation is employed for a considerable number of commercial processes such as the production of alcohol, kerosene gasoline, etc. During a distillation, it is important that a drop of condensate be suspended from the thermometer because it allows steady distillation and a stable temperature.
The correct answer is - phytoplankton.
The phytoplantkon is an organism that is at the bottom of the food chain, and it is the basis for the food chain in the marine environments. It is an organism that is an autotroph, which basically means that it manages to produce complex organic compounds from simple substances that are present in its surroundings, and very importantly, it uses mostly light or inorganic chemical reactions, thus the phytoplankton is a producer, and it is a main food source for large number of marine species.
