All adaptations have a downside: horse legs are great for running on grass, but they cannot scratch their backs; mammals' hair helps temperature, but offers a niche for ectoparasites; the only flying penguins do is under water. Adaptations serving different functions may be mutually destructive. Compromise and makeshift occur widely, not ...
Fire adaptations are traits of plants and animals that help them survive wildfire or to use resources created by wildfire. These traits can help plants and animals increase their survival rates during a fire and/or reproduce offspring after a fire. Both plants and animals have multiple strategies for surviving and reproducing after fire.
Animals such as penguins have adapted to live in very cold conditions. [1] Ibex in an alpine habitat. In ecology, habitat refers to the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species.
A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources (for example, a heterotroph with a varied diet). A specialist species can thrive only in a narrow range of environmental conditions or has a limited diet. Most organisms do not all fit neatly into either ...
Many species have varying levels of climatic adaptation. Differing average annual temperatures can have varying effects on a population's average body temperature, metabolic rate, or body size. But the actual effect of climatic adaptation depends greatly on the species in question and often the amount of genetic variability within that species.
Adaptations in diet also help in the prevention of parasitic infection. By avoiding foods that have high potential for parasitic contamination, as well as including food items that contain anti-parasitic properties in the diet. These anti-parasitic properties can be used in a self-medicating way, either prophylactically or therapeutically. [13]
Animals that practice group-living often benefit from assistance in parasite removal, access to more mates, and conservation of energy in foraging. [50] Initially, the most obvious form of animal cooperation was kin selection , but more recent studies focus on non-kin cooperation, where benefits may seem less obvious.
Animals have several characteristics that set them apart from other living things. Animals are eukaryotic and multicellular. [14] Unlike plants and algae, which produce their own nutrients, [15] animals are heterotrophic, [16] [17] feeding on organic material and digesting it internally. [18] With very few exceptions, animals respire aerobically.
