In deserts, secondary consumers include species such as snakes, spiders and raptors that feed on smaller animals classified as herbivores. Secondary consumers, unlike primary consumers, eat mostly meat. They take the form of animals such as roadrunners, foxes, owls, hawks and vultures.Know More
Secondary consumers rank high on the desert food chain; only tertiary consumers rank higher. The food chain begins with producers. Those organisms, primarily plants and vegetation, make their own food supplies. Most perform photosynthesis, which involves absorbing sunlight and converting light to energy. Plants make energy in the form of sugars called glucose. Producers supply primary consumers with energy.
Primary consumers include small mammals like rodents, chipmunks and squirrels. They exist in larger numbers in most desert environments than secondary consumers, giving secondary consumers a variety of food choices. Some predators, like rattlesnakes, make noise to catch prey. Others, like the Elf Owl, take a silent, stealthy approach instead. These owls produce no noise during flight. They sneak up on unsuspecting predators; soft feathers on their wing tips damper noise. Elf owls reside in deserts across the American Southwest, and extend their range into parts of Mexico as well. Elf owls feed primarily on insects like moths, beetles and scorpions. In turn, other desert predators such as foxes and coyotes consume owls.Learn more about Economics
Primary and secondary consumers create the backbone of food chains: primary consumers, such as small bugs and insects, feed on plant matter and organic material while secondary consumers eat other animals. In addition to primary and secondary consumers, some food chains have a third level of consumers called tertiary consumers. These consumers are classified as carnivores, along with secondary consumers, and take the form of predatory birds and larger mammals.Full Answer >
A secondary ecological succession will follow the destruction of the vegetation in an ecosystem, even if it has been completely destroyed in a major forest fire, provided that the soil has been left intact. Seeds brought into the area by wind or by animals, or seeds that were left below the soil before the disturbance, will take root and become the pioneer plants of the secondary succession. Herbaceous plant growth, such as grass, will begin to grow first, followed by bushes and the first-emerging trees, and lead ultimately to a restoration of the original ecosystem.Full Answer >
Consumer sovereignty is the economic theory that consumers can best determine what goods and services should be produced in a society. Firms, such as businesses and companies, produce whatever the consumer prefers. Economist William Harold Hutt coined this term in his 1936 book "Economists and the Public."Full Answer >
Allocation in economics is an analysis of how limited resources, also called factors of production, are distributed among producers, and how scarce goods and services are divided among consumers. Accounting cost, opportunity cost, economic cost and other costs are considered in this analysis.Full Answer >
