Efficiency of searching (a). The Lotka-Volterra model, often recognized as predator-prey dynamics, includes a set of differential equations that are non-linear and first-order. This model helps explain fluctuations within biological systems as two species interact, one being the predator and the other the prey. In the context of the question, the phrase "searching efficiency (a)" characterizes the rate at which predators change in relation to their ability to detect, capture, and consume prey.
