Onsite sewage facilities (OSSF), also called septic systems, are wastewater systems designed to treat and dispose of effluent on the same property that produces the wastewater, in areas not served by public sewage infrastructure. A septic tank and drainfield combination is a fairly common type of on-site sewage facility in the Western world.
Biological rules and laws are often developed as succinct, broadly applicable ways to explain complex phenomena or salient observations about the ecology and biogeographical distributions of plant and animal species around the world, though they have been proposed for or extended to all types of organisms. Many of these regularities of ecology ...
"Whenever a spontaneous process is too slow or too inefficient a protein will evolve to speed it up or make it more efficient.". This "rule" comments on the fact that there are a great number of proteins in all organisms which fulfil a number of different functions through modifying chemical or physical processes.
The rules are generally regarded as hypotheses that need to be tested on an individual basis, not as accepted conclusions. This is the reason why Diamond's results sparked nearly two decades worth of controversy in the literature, from the late seventies through the late nineties and is considered a turning point in community ecology .

[2] In the study of community ecology, competition within and between members of a species is an important biological interaction. Competition is one of many interacting biotic and abiotic factors that affect community structure, species diversity, and population dynamics (shifts in a population over time). [3]
Tests of sufficiency in biology are used to determine if the presence of an element permits the biological phenomenon to occur. In other words, if sufficient conditions are met, the targeted event is able to take place. However, this does not mean that the absence of a sufficient biological element inhibits the biological event from occurring.
Biology is the scientific study of life. [1] [2] [3] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [1] [2] [3] For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes, which
Consider the two species case, where R* 1 < R* 2. When species 2 is at equilibrium, R = R* 2, and species 1's population will be increasing. When species 1 is at equilibrium, R = R* 1, and species 2's population will be decreasing. [1] This method has been extended to analyze more complex models, such as species with a Type II functional ...
