al-Jāḥiẓ (الجاحظ) (full name Abū ʿUthman ʿAmr ibn Baḥr al-Kinānī al-Baṣrī أبو عثمان عمرو بن بحر الكناني البصري) (born 776, in Basra – December 868/January 869) was an Arab prose writer and author of works of literature, Mu'tazili theology, and politico-religious polemics.
An apex predator, also known as an alpha predator or top predator, is a predator at the top of a food chain, with no natural predators.
Archaea (or or) constitute a domain of single-celled microorganisms.
An autotroph ("self-feeding", from the Greek autos "self" and trophe "nourishing") or producer, is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) from simple substances present in its surroundings, generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis).
Bacteria (common noun bacteria, singular bacterium) is a type of biological cell.
Biological organization is the hierarchy of complex biological structures and systems that define life using a reductionistic approach.
Biomagnification, also known as bioamplification or biological magnification, is the increasing concentration of a substance, such as a toxic chemical, in the tissues of tolerant organisms at successively higher levels in a food chain.
Cengage is an educational content, technology, and services company for the higher education, K-12, professional, and library markets worldwide.
Charles Sutherland Elton (29 March 1900 – 1 May 1991) was an English zoologist and animal ecologist.
In chemistry, chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances.
In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or methane as a source of energy, rather than sunlight, as in photosynthesis.
A cold seep (sometimes called a cold vent) is an area of the ocean floor where hydrogen sulfide, methane and other hydrocarbon-rich fluid seepage occurs, often in the form of a brine pool.
Consumers are organisms that eat organisms from a different population. These organisms are formally referred to as heterotrophs, which include animals, some bacteria and fungi.
In mathematics, a variable may be continuous or discrete.
Decomposers are organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition.
The deep sea or deep layer is the lowest layer in the ocean, existing below the thermocline and above the seabed, at a depth of 1000 fathoms (1800 m) or more.
Detritivores, also known as detrivores, detritophages, detritus feeders, or detritus eaters, are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as feces).
An earthworm is a tube-shaped, segmented worm found in the phylum Annelida.
An ecological pyramid (also trophic pyramid, eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bio productivity at each trophic level in a given ecosystem.
Ecology (from οἶκος, "house", or "environment"; -λογία, "study of") is the branch of biology which studies the interactions among organisms and their environment.
An ecosystem is a community made up of living organisms and nonliving components such as air, water, and mineral soil.
An ecosystem model is an abstract, usually mathematical, representation of an ecological system (ranging in scale from an individual population, to an ecological community, or even an entire biome), which is studied to better understand the real system.
Ecotoxicology is the study of the effects of toxic chemicals on biological organisms, especially at the population, community, ecosystem, and biosphere levels.
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.
A food web (or food cycle) is a natural interconnection of food chains and a graphical representation (usually an image) of what-eats-what in an ecological community.
A fungus (plural: fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.
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).
The grizzly bear (Ursus arctos ssp.) is a large population of the brown bear inhabiting North America.
A heterotroph (Ancient Greek ἕτερος héteros.
Hydrogen sulfide is the chemical compound with the chemical formula H2S.
A hydrothermal vent is a fissure in a planet's surface from which geothermally heated water issues.
Feeding is the process by which organisms, typically animals, obtain food.
Lithotrophs are a diverse group of organisms using inorganic substrate (usually of mineral origin) to obtain reducing equivalents for use in biosynthesis (e.g., carbon dioxide fixation) or energy conservation (i.e., ATP production) via aerobic or anaerobic respiration.
The Lotka–Volterra equations, also known as the predator–prey equations, are a pair of first-order nonlinear differential equations, frequently used to describe the dynamics of biological systems in which two species interact, one as a predator and the other as prey.
Methane is a chemical compound with the chemical formula (one atom of carbon and four atoms of hydrogen).
Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants known as grasses, commonly referred to collectively as grass.
Pollution is the introduction of contaminants into the natural environment that cause adverse change.
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium.
Science, also widely referred to as Science Magazine, is the peer-reviewed academic journal of the American Association for the Advancement of Science (AAAS) and one of the world's top academic journals.
Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.
The Sun is the star at the center of the Solar System.
Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light.
In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species.
The trophic level of an organism is the position it occupies in a food chain.
A woodlouse (plural woodlice) is a terrestrial isopod crustacean with a rigid, segmented, long exoskeleton and fourteen jointed limbs.
