An example of this conditioning in a consumer behaviour context is a cinema using a consumer incentive scheme. A consumer given a card which entitles the person to a free movie if the person brings a friend and free popcorn on Tuesdays with the purchase of a ticket per se , they are more likely to go to a movie when perhaps they wouldn't have ...
The rate at which the consumer encounters food items per unit of food density is called the attack rate, a. The average time spent on processing a food item is called the handling time, h. Similar equations are the Monod equation for the growth of microorganisms and the Michaelis–Menten equation for the rate of enzymatic reactions. [4]
An example is the koala, because it feeds only on eucalyptus leaves. Primary consumers that feed on many kinds of plants are called generalists. Secondary consumers are small/medium-sized carnivores that prey on herbivorous animals. Omnivores, which feed on both plants and animals, can be considered as being both primary and secondary consumers.

Consumer–resource interactions are the core motif of ecological food chains or food webs, [1] and are an umbrella term for a variety of more specialized types of biological species interactions including prey-predator (see predation), host-parasite (see parasitism), plant-herbivore and victim-exploiter systems.
[1] [6] Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. [7] [8] [9] Like other scientists, biologists use the scientific method to make observations, pose questions, generate hypotheses, perform experiments, and form conclusions about the world around ...
An experimental design (below) in a Choice Experiment is a strict scheme for controlling and presenting hypothetical scenarios, or choice sets to respondents. For the same experiment, different designs could be used, each with different properties. The best design depends on the objectives of the exercise.
Further up the food chain, the concentration of the contaminant increases, sometimes resulting in the top consumer dying. Biomagnification , also known as bioamplification or biological magnification , is the increase in concentration of a substance, e.g a pesticide, in the tissues of organisms at successively higher levels in a food chain .
