Absorption: process of taking substances such as water and nutrients into the body through cell membranes or, in plants, through root hairs . Accuracy: a measure of the degree of agreement between a measured quantity value and a true quantity value . Inactive refers to a spring where no free water was visible at the ground surface, with the exception of some mounded mud springs within the Eulo district. Adsorption: adherence of a gas, liquid or dissolved chemical to the surface of a solid . Aerobic: the presence of oxygen .
Contrast with ingestion. Aerobic organisms require oxygen for their life processes. Anaerobic organisms do not require oxygen for their life processes, in fact oxygen is toxic to many of them. Most anaerobic organisms are bacteria or archaeans. Most plants are autotrophs, as are many protists and bacteria. Contrast with consumer. Autotrophs may be photoautotrophic , using light energy to manufacture food, or chemoautotrophic , using chemical energy.
Definitions have been carefully reviewed to assure accord with current professional usuage. Appreciation is tendered to biologists of the following Environmental Protection Agency activities for this service: Robert S. Terms specifically identifying or describing organisms have generally been excluded from this work. For this information the reader is referred to the selected references presented in the appendix. Glossaries of terminology related to other disciplines concerned with water pollution control are also listed in the appendix.
Login Sitemap Contact. Chinook, or king, salmon: One of seven species of salmon in the northern Pacific Ocean. There are four runs, or genetically distinct races, in the Sacramento-San Joaquin river system. Many have been made extinct and most surviving runs are in decline. One of the largest runs, the Sacramento River winter-run Chinook, has been listed as an endangered species.
Many of these words represent ideas that cannot be seen e. Check out our pages on teaching literacy here. Ecologists are interested in studying the relationships both within and between these groups. From big idea: organisms require a supply of energy and materials for which they often depend on, or compete with, other organisms. Linked knowledge: photosynthesis , evolution , respiration. Misconception [scientific idea]: organisms exist for the benefit of humans [organism exist as a result of evolution] Where to start? This ecosystem in a bottle is a useful framework to begin thinking about ecosystems.
Brook, Corey J. Many areas of science have adopted nomenclature rules that facilitate research and communication. In contrast, ecological terminology is constantly redefined across disciplines, plagued with synonymy and polysemy, and foundational terms and the theories and hypotheses behind them are overlooked. We contend that this situation handicaps the progress of ecology. We review the causes and consequences of terminological uncertainty and propose a convention of ecological nomenclature CEN as an indispensable requirement of ecological synthesis. The core components of a CEN are its endorsement by a transnational institution; a policy framework managed by an advisory committee; and a centralized, peer-reviewed revision of terminology whereby ecologists are proponents and users of a unique, open-access repository of terms, definitions, and ontologies. A CEN should become the basis of a cross-disciplinary platform of communication among ecologists, journals, and the public and aligns with the ongoing initiative toward data globalization in ecology and other disciplines.
Biomagnification is also known as bio amplification; in this, the concentration of the toxicants increases at the successive trophic levels. It is due to the reason that toxic elements cannot be absorbed and simultaneously they get transferred to the successive higher trophic levels resulting in more concentration of toxicants at the higher trophic level.

Темнота стала рассеиваться, сменяясь туманными сумерками. Стены туннеля начали обретать форму. И сразу же из-за поворота выехала миниатюрная машина, ослепившая ее фарами. Сьюзан слегка оторопела и прикрыла глаза рукой. Ее обдало порывом воздуха, и машина проехала мимо.
Он знал, что Фонтейн прав: у них нет иного выбора. Время на исходе. Джабба сел за монитор.
