Define stochasticity

Webstochasticity, genetic drift, and environmental variation can interact to doom a small population to extinction. This is called an extinction vortex, and it is due to a positive feedback loop (igure 12.1): the negative consequences of lower effective population size make the population smaller, causing stronger negative effects, leading to an ... Stochastic refers to the property of being well described by a random probability distribution. Although stochasticity and randomness are distinct in that the former refers to a modeling approach and the latter refers to phenomena themselves, these two terms are often used synonymously. Furthermore, in probability theory, the formal concept of a stochastic process is also referred to as a random process.
