Also Gause's law. A biological rule which states that two species cannot coexist in the same environment if they are competing for exactly the same resource, often memorably summarized as "complete competitors cannot coexist". coniferous forest One of the primary terrestrial biomes, culminating in the taiga. conservation biology The study of Earth's biodiversity with the aim of protecting and ...
insecticide - a pesticide used to control insects in all developmental forms. Integrated Pest Management (IPM) - a pest control strategy that uses an array of complementary methods: natural predators and parasites, pest-resistant varieties, cultural practices, biological controls, various physical techniques, and the strategic use of pesticides.
Climate processes largely control the distribution, size, shape and properties of living organisms on Earth.For instance, the general circulation of the atmosphere on a planetary scale broadly determines the location of large deserts or the regions subject to frequent precipitation, which, in turn, greatly determine which organisms can naturally survive in these environments.
Also called an antibacterial. A type of antimicrobial drug used in the treatment and prevention of bacterial infections. Archaea One of the three recognized domains of organisms, the other two being Bacteria and Eukaryota. artificial selection Also called selective breeding. The process by which humans use animal breeding and plant breeding to selectively control the development of particular ...
Biogeochemistry is the scientific discipline that involves the study of the chemical, physical, geological, and biological processes and reactions that govern the composition of the natural environment (including the biosphere, the cryosphere, the hydrosphere, the pedosphere, the atmosphere, and the lithosphere).
For levels larger than Biosphere or Ecosphere, see Earth's location in the Universe More complex schemes incorporate many more levels. For example, a molecule can be viewed as a grouping of elements , and an atom can be further divided into subatomic particles (these levels are outside the scope of biological organisation).
They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [28]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).
In the context of natural systems, command and control management attempts to control nature in order to improve natural resource extractions, establish predictability, and reduce threats. [20] Command and control strategies include the use of herbicides and pesticides to improve crop yields; [ 20 ] the culling of predators to protect game bird ...
