Unit 1 Biology

precipitation that is the result of air pollution reacting with water molecules in the atmosphere leading to the destruction of forest and lake ecosystems

organisms in this kingdom are multicellular heterotrophs without cell walls

kingdom that includes bacteria that live in extreme environments

two-word naming system for all organisms developed by Linnaeus; gives the scientific name (consisting of genus and species); ex. Homo sapiens

the increase in concentration of pollutants in the tissues of organisms as you move up trophic levels in an ecosystem; aka biomagnification

incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

Largest number of individuals of a population that a environment can support

The most basic unit of all organisms, all living things are made up of cells, they can either be multicellular or unicellular.

Groups of organisms based on similar traits.

Grouping of objects or organisms based on similarities.

describes global warming which is the ongoing increase in temperature.

The competition between organisms for resources such as food and water.

An organism that consumes other organisms for nutrients.

Organisms such as fungi and bacteria that break down and absorb nutrients from dead organisms.

the destruction of forests

A series of paired statements used to help identify an organism

the largest taxon; there are 3--Bacteria, Archaea, and Eukarya

A group of prokaryotic organisms with strong cell walls and many structures, They may be autotrophs.

Unicellular of multicellular organisms such as yeast, plants and animals that are composed of Eukaryotic cells and membrane bound organelles.

excessive nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plants/algae and a death of animals from a lack of oxygen.

j-shaped, explosive pattern of population growth

normal warming effect caused when the sun's rays are trapped by gases in the Earth's atmosphere; without this, the Earth would be a ball of ice

The loss of natural habitat for species that can lead to extinction

an organism that must get food from its environment; aka consumer; one example is animals

plants and animals that are deliberately/accidentally introduced into an area whose populations explode because they have no known natural predators and out-compete native species for resources leading to their decline

made of two or more cells

mutualism

transfer of nitrogen from the atmosphere to the soil, to living organisms, and back to the atmosphere

process of converting nitrogen in the air, into a form that plants and animals can use (nitrates and nitrites)

organism

body of water used to dispose of animal wastes on farms; these become problematic when they flood into rivers/drinking water supplies

made of one cell

growth response of a plant to a stimulus

branch of biology that involves classifying organisms into groups based upon similar characteristics

a close relationship between two species living together

when a young mammal nurses from its mother

commitment to the responsible management of natural resources and sustainable actions to help preserve the environment

a reproductive cell with a hard, protective coating; made by bacteria, fungi, and some plants like ferns

the smallest/most specific taxon; a group of organisms that can interbreed and produce fertile offspring

the most diverse kingdom; some are plant-like, some are animal-like, and some are fungus-like; examples include: euglena, paramecium, and amoeba

a bacterial cell; a cell that lacks a nucleus and membrane bound organelles

an organism that can make its own food; aka "autotroph"

kingdom with organisms that are photosynthetic autotrophs and have cell walls made of cellulose

an organ in the uterus of a pregnant mammal, that nourishes the fetus through the umbilical cord

form of symbiosis in which one organism, the parasite, benefits and the other organism, the host, is harmed; ex. tick and a dog
