The Daisyworld model is a simplified representation of an ecological system created by James Lovelock and Andrew Watson as an illustration of the Gaia hypothesis, which posits that life interacts with the physical environment to create a self-regulating, stable climate conducive to sustaining life. In the model, a hypothetical planet's temperature is regulated by the albedo effect of two types of daisies—black and white—that either absorb or reflect heat, demonstrating how life-forms can collectively maintain equilibrium within an ecosystem.
