Aquatic(s) means relating to water; living in or near water or taking place in water; does not include groundwater, as "aquatic" implies an environment where plants and animals live.
An ecosystem is a community made up of living organisms and nonliving components such as air, water, and mineral soil. Ecosystems may be studied either as contingent collections of plants and animals, or as structured systems and communities that are governed by general rules. The biotic and abiotic components interact through nutrient cycles and energy flows. Ecosystems include a network of interactions among organisms, and between organisms and their environment. Ecosystems can be of any size but one ecosystem has a specific, limited space. Some scientists view the entire planet as one ecosystem.
Protection may refer to:
To protect those who are not able to protect themselves is a duty which every one owes to society.
Lord Macnaghten‎, Jenoure v. Delmege (1890), 60 L. J. Rep. (N. S.) Q. B. 13; reported in James William Norton-Kyshe, Dictionary of Legal Quotations (1904), p. 212.
Protection is not a principle, but an expedient.
Benjamin Disraeli, Speech in the House of Commons (17 March 1845).
The organization of life extends beyond the individual organism to the biosphere, the zone of air, land, and water at the surface of the Earth where organisms exist. Individual organisms belong to a population, which is all the members of a species within a particular area. The populations of a community interact among themselves and with the physical environment (e.g., soil, atmosphere, and chemicals), thereby forming an ecosystem.
