An organism that produces its own food. Autotrophs may be photoautotrophic (fed by using light) or chemoautotrophic (by using chemical energy). See Heterotroph.
Industry:Biology
A fluid-filled sac that safely enfolds a growing mammal, reptile, or bird embryo. The amnion is thought to have allowed animals to come out of the sea onto land.
Industry:Biology
A cross between two genetically diverse parent plants. Agribusiness companies produce and sell hybrids that do not reproduce in order to retain a monopoly on seeds.
Industry:Biology
The transformation of one physical state into another--gas into liquid, solid into gas, etc. Always requires an exchange of energy, whether an increase or decrease.
Industry:Biology
Animals with a notochord--a long, cartilaginous support column running most of the body's length--located between the stomach and a fluid-filled dorsal nerve cord.
Industry:Biology
How easily soils and rocks transport water horizontally and vertically. Shale is porous and therefore permeable, as is sand and gravel; granite and clay are not.
Industry:Biology
Only about ten percent of the chemical energy available at one trophic level in a food chain is converted into a usable form for organisms at the next trophic level.
Industry:Biology
A three-atom oxygen molecule that in its gaseous state screens ultraviolet radiation. The protective ozone layer hangs 10 to 50 kilometers above the Earth's surface.
Industry:Biology
A molecule composed of one type of atom (e. G. , Carbon, Hydrogen, Helium). At present the Periodic Table contains 112 elements. Two or more elements form a compound.
Industry:Biology
Fats, waxes, oils: greasy organic hydrocarbons insoluble in water. With proteins and carbohydrates, membrane-strengthening lipids provide cells with their structure.
