Biocenose of littoral upper and lower rocks is a very narrow strip (a few dozen centimetres high) where mostly lithophytic cyanobacteria live, upon whom periwinkles and limpets feed, and during the high water some organisms of the inner part of the sublittoral, like sea-urchins, too.
Typical coralligenous aspect of this biocenose is composed by prominent sciaphylic colonies with dominating calcified algae, corals, bryozoa and sponges.
Biocenose of semi-dark caves is also the part of the outer part of the sublittoral and it also appears as an enclave of the inner part of the sublittoral.

For modern ecologists, ecology can be studied at several levels: populationlevel (individuals of the same species), biocenose level (or community ofspecies), ecosystem level, and biosphere level.
The Earth, from an ecological point of view, consists of several compartments, the hydrosphere (or sphere of water), the lithosphere (orsphere of soils and rocks) and the atmosphere (or sphere ofthe air).
The most significant relation isthe relation of predation (to eat or to be eaten), which leads to the essentialconcepts in ecology of food chains (for example, the grass is consumed by theherbivore, itself consumed by a carnivore, itself consumed by a carnivore of larger size).

 Biocoenosis - Wikipedia, the free encyclopedia
A biocoenosis (alternatively, biocoenose or biocenose), termed by Karl Möbius in 1877, describes all the interacting organisms living together in a specific habitat (or biotope).
The extent or geographical area of a biocenose is limited only by the requirement of a more or less uniform species composition (Kendeigh, 1961).
An ecosystem, as originally defined by Tansley (1935), is a biotic community (or biocoenosis) along with its physical environment (or biotope as defined by many known ecologists).

When a population consists of an insufficient number of individuals, that population is threatened with extinction; the extinction of a species can approach when all biocenoses composed of individuals of the species are in decline.
The most significant relation is the relation of predation (to eat or to be eaten), which leads to the essential concepts in ecology of food chains (for example, the grass is consumed by the herbivore, itself consumed by a carnivore, itself consumed by a carnivore of larger size).
A high predator to prey ratio can have a negative influence on both the predator and prey biocenoses in that low availability of food and high death rate prior to sexual maturity can decrease (or prevent the increase of) populations of each, respectively.

Biocenose (ou comunidade) é a associação de organismos de espécies diferentes que habitam um biótopo comum.
O termo "biocenose" (do grego bios, vida, e koinos, comum, público) foi criado pelo zoólogo alemão K.A. Möbius, em 1877, para ressaltar a relação de vida em comum dos seres que habitam determinada região.
A biocenose de uma floresta, por exemplo, compõe-se de populações de arbustos, árvores, pássaros, formigas, microorganismos etc., que convivem e se inter-relacionam.

Towards 1850 there was a breakthrough in the field with the publishing of the work of Charles Darwin on The Origin of Species : Ecology passed from a repetitive, mechanical model to a biological, organic, and hence evolutionary model.
Human ecology began in the 1920s, through the study of changes in vegetation succession in the city of Chicago.

Biocenose is a group of living organisms, united by the attraction of different environmental factors.
The mutual relation of components is such, that amendments, referred only to one kind, can reflect on all the biocenose and even cause its decomposition.
Most ecosystems have been formed during a long-term evolution and are the result of adoption of species to the environment.

Het concept van een onderlinge afhankelijkheid van planten en dieren werd voor het eerst geformuleerd door de Amerikaan Alfred Russel Wallace.
In 1877 stelde Karl Möbius voor om de term biocenose te gebruiken voor een groep met elkaar samenlevende planten en dieren.
In 1935 introduceerde Arthur Tansley het begrip ecosysteem voor de biocenose (de organismen) in samenhang met hun omgeving (de biotoop).

Cando sobrevén unha perturbación no medio, ten lugar un profundo trastorno na estructura das poboacións, que se manifesta por un troco na dominancia relativa das especies, acompañado de substitucións da fauna e flora, podendo en casos extremos chegar á desaparición completa da biocenose.

Quando vivemos em um ecossistema natural, nós fazemos parte dele, e seu gerenciamento se dá de forma conjunta com os demais seres vivos.
Um ecossistema artificial, como uma cidade, já tem maior parte do gerenciamento a cargo do ser humano, de maneira que diminuímos a interferência da biocenose nessa administração.
