Given any set A whose elements are arranged on a circle, one can define a ternary relation R on A, i.e. a subset of A 3 = A × A × A, by stipulating that R(a, b, c) holds if and only if the elements a, b and c are pairwise different and when going from a to c in a clockwise direction one passes through b.
If A is a set, then the absolute complement of A (or simply the complement of A) is the set of elements not in A (within a larger set that is implicitly defined). In other words, let U be a set that contains all the elements under study; if there is no need to mention U, either because it has been previously specified, or it is obvious and unique, then the absolute complement of A is the ...
indicates that the column's property is always true for the row's term (at the very left), while indicates that the property is not guaranteed in general (it might, or might not, hold).
Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...

The USDA's original food pyramid, from 1992 to 2005 [1]. A food pyramid is a representation of the optimal number of servings to be eaten each day from each of the basic food groups. [2]
In probability theory and statistics, the Poisson distribution (/ ˈ p w ɑː s ɒ n /) is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time if these events occur with a known constant mean rate and independently of the time since the last event.

Gonimbrasia belina is a species of emperor moth which is native to the warmer parts of southern Africa.Its large edible caterpillar, known as the mopane worm, madora, amacimbi “pigeon moth”, masonja or Seboko sa Mongana, feeds primarily but not exclusively on mopane tree leaves.
