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.
Consumers are typically viewed as predatory animals such as meat-eaters. However, herbivorous animals and parasitic fungi are also consumers. To be a consumer, an organism does not necessarily need to be carnivorous; it could only eat plants (producers), in which case it would be located in the first level of the food chain above the producers.
However, little literature has considered the link between consumption behaviour and the basics of human biology. Segmentation by biological-driven demographics such as sex and age are already popular and pervasive in marketing. As more knowledge and research is known, targeting based on consumers' biology is of growing interest and use to ...
Data collected in experiments are used to estimate effect size, test the validity of economic theories, and illuminate market mechanisms. Economic experiments usually use cash to motivate subjects, in order to mimic real-world incentives. Experiments are used to help understand how and why markets and other exchange systems function as they do.
Economists consider “science” as the search and production of knowledge using known starting conditions. [2] Knowledge can be considered a public good, due to the fact that its utility to society is not diminished with additional consumption (non-rivalry), and once the knowledge is shared with the public it becomes very hard to restrict access to it or use of it (non-excludable).
Animals such as the fruit fly Drosophila melanogaster, the zebrafish, the chicken and the house mouse, serve a major role in science as experimental models, [32] both in fundamental biological research, such as in genetics, [33] and in the development of new medicines, which must be tested exhaustively to demonstrate their safety.
The theory of consumer choice is the branch of microeconomics that relates preferences to consumption expenditures and to consumer demand curves.It analyzes how consumers maximize the desirability of their consumption (as measured by their preferences subject to limitations on their expenditures), by maximizing utility subject to a consumer budget constraint.

A social experiment is a method of psychological or sociological research that observes people's reactions to certain situations or events. The experiment depends on a particular social approach where the main source of information is the participants' point of view and knowledge.
