ตัวกรองผลการค้นหา
Procaryotic organisms
แปลว่า(Environmental Engineering) Organisms which do not have a cellular membrane.
Eucaryotic organisms
แปลว่า(Environmental Engineering) Organisms which possess a nuclear membrane. This includes all known organisms except viruses and bacteria.
Decomposers
แปลว่า(Environmental Engineering) Organisms which utilize energy from wastes or dead organisms. Decomposers complete the cycle by returning nutrients to the soil or water and carbon dioxide to the air or water.
Autotrophs
แปลว่า(Environmental Engineering) A group of organisms capable of obtaining carbon for synthesis from inorganic carbon sources such as carbon dioxide and its dissolved species (the carbonates). This group includes plants and algae.
Heterotrophic
แปลว่า(Environmental Engineering) A group of organisms which obtain carbon for synthesis from other organic matter or proteins.
Ecosystem
แปลว่า(Environmental Engineering) An organism or group of organisms and their surroundings. The boundary of an ecosystem may be arbitrarily chosen to suit the area of interest or study.
Producers
แปลว่า(Environmental Engineering) Autotrophic organisms which produce protoplasm using inorganic carbon and energy from the sun.
Trophic level
แปลว่า(Environmental Engineering) A level in the food chain. The first trophic level consists of the primary producers, autotrophs. The second trophic level is vegetarians which consume autotrophic organisms.
Bacteria
แปลว่า(Environmental Engineering) One celled microorganisms which do not have a nuclear membrane.
Photoautotrophic
แปลว่า(Environmental Engineering) Organisms which utilize inorganic carbon dioxide for protoplasm synthesis and light for an energy source. See autotrophic and chemoautotrophic.
Infectious disease
แปลว่า(Environmental Engineering) A disease caused by pathogenic organisms.
Virus
แปลว่า(Environmental Engineering) A submicroscopic genetic constituent which can alternate between two distinct phases. As a virus particle, or virion, it is DNA or RNA enveloped in an organic capsule. As an intracellular virus, it is viral DNA or RNA inserted into the host organisms DNA or RNA.
