Answer: As the Oxford dictionary states it, Probability means ‘The extent to which something is probable; the likelihood of something happening or being the case’.
In mathematics too, probability indicates the same – the likelihood of the occurrence of an event.
Examples of events can be :
Tossing a coin with the head up
Drawing a red pen from a pack of different coloured pens
Drawing a card from a deck of 52 cards etc.
Either an event will occur for sure, or not occur at all. Or there are possibilities to different degrees the event may occur.
An event that occurs for sure is called a Certain event and its probability is 1.
An event that doesn’t occur at all is called an impossible event and its probability is 0.
This means that all other possibilities of an event occurrence lie between 0 and 1.

<u>Answer</u>:
Phytoplankton feed on nutrients brought up by upwelling.
Hence, option D is the right answer.
<u>Explanation</u>:
Phytoplankton are microscopic marine plants, i.e they live in water bodies. They are autotrophic, i.e they prepare their own food. They are called phytoplankton because they absorb photo energy i.e sunlight. They absorb carbon dioxide and release oxygen. As they need to absorb sunlight, they are present near the surface of the water.
Upwellings are ocean currents which bring nutrients from deep cold water to the surface. Upwellings happen because of the rotation of the Earth and winds. The phytoplankton depend on the nutrients brought by the upwellings to prepare their food using sunlight and they form the food for various sea animals.
