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
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 >
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 >
Monopolies have a negative effect on the entire economy by making it harder for consumers to purchase goods, a trend that leads to lower production in the system. High prices do not affect only the consumer, they end up hurting the monopoly itself. Even systems with more than one competitor can be monopolistic if there are only a few. Competition benefits every human component in the economy.Full Answer >
In economics, demand is the quantity of goods or services that consumers are able and willing to buy at a given price at a particular time. The law of demand provides that, if all other market factors remain constant, the demand for goods and services increases as their price decreases.Full Answer >
