Food is essential to human life, which means that we must have it to survive. Essential can also apply to something that makes up the essence, or necessary qualities or attributes, of a thing (a good safecracker is essential to our plan). Clothing is indispensable in Northern climates, which means that it cannot be done without if the specified or implied purpose — in this case, survival — is to be achieved. Necessary applies to something without which a condition cannot be fulfilled (cooperation was necessary to gather the harvest), although it generally implies a pressing need rather than absolute indispensability. Requisite refers to that which is required by the circumstances (the requisite skills for a botanist) and generally describes a requirement that is imposed from the outside rather than an inherent need.
