Organisms rely on and interact with each other in a number of different ways. Some species serve as food for carnivores. Some organisms are parasites that derive their resources at the expense of other species, while others engage in mutualistic relationships, in which both organisms benefit. Other species depend on similar resources so they are in competition with each other.Know More
Animals that eat other animals are called predators. Examples of predators include spiders, snakes and sharks. The animals these predators consume are called prey species. For example, some prey species of spiders include flies, roaches and beetles. Many animals are both predators and prey, such as a snake that eats a rodent but is in turn eaten by a hawk.
Examples of parasites include intestinal worms, protozoans and ticks. These animals derive nutrition from other animals, called hosts. For example, a tick attaches itself to an animal and then begins to drink blood from the host. Often, the host only experiences a minor inconvenience from the parasite’s activities, but in some cases, the parasites can cause the host to become weak or even die.
In some cases, organisms have a mutually beneficial relationship. As an example, the activities of leaf-cutter ants encourage the growth of fungus that serves as food for the ants. In this case, the fungus benefits from the ants, while ants benefit from the fungus.Learn more about Environmental Science
Ecology is the scientific study of interactions between organisms and their environment. Environmental conservation is the practice of protecting the natural environment on individual, organizational or governmental levels for the benefit of both the natural world and humans.Full Answer >
Biodiversity is important in ecosystems because it prevents extinction of species, allows organisms to adapt to changes in the environment and provides a wide range of materials and foods for survival. Biodiversity is categorized into species diversity, genetic diversity and ecosystem diversity.Full Answer >
The environments that organisms live have unique features and qualities that shape the development of the genetic and phenotypic characteristics of resident organisms to allow them to become suited for life in those regions better. The environment in which species live can be considered a biological and physical environment. These environments vary around the world, and may be hot, cold, arid or moist.Full Answer >
Decomposers help reclaim carbon from dead organisms and put it back into the carbon cycle so living organisms can use it. Decomposers break down dead plants, animals and waste products. This process releases carbon dioxide through cellular respiration.Full Answer >
