process that changes or transforms one set of chemical into another set of chemicals
organism that relies on another organisms for its energy and food supply also called hetesotraph?
organism that is able to capture energy from sunlight or chemicals and use it to produce its own food from inorganic compound also called a producer
process used by plants and other autotrophs to capture light energy and used it to power chemical reactions that can vert carbon dioxide and water into oxygen and energy rich carbohydrates
illustration of the relative amounts of energy or matter contined within each trophic level in a given food chain or web
ability of an oranism to survive and reproduce under circumstnaces that differ from their optimal conditions
full range of physical and biological conditions in which an organism lives and the way in which the organism thoes? conditions
competitive exclusion pronciple
principle that states that no two species can occupy the same niche in the same habitat at the same time
interaction in which one organism (the predntor)captures and feeds on another organims(the prey)
single species that is not usually abundant in a community yet exerts strong control on the structure of a community
symbiotic relationship in which one organism lives on or inside another organism and harms it
symbiotic relationship in which one organism benefits and the other is neither help or harm
succesion that occurs in an area in which no trace of a provious community is present
growth pattern in which the individuals in a population reproduce at a consistent rate
growth pattern in which a populations growth slows and then stops following a period of exponential growth
largest number of individuals of a particular species that a paricular environment can support
dinsity independent limiting factor
limiting factor that affects all population in similar ways regardiless of the population density
strategy focusing nutural resources without deplefing???? them and for providing human nees without causing long term environment harm
lower land praductivity caused by overfarming overgrazing seasonal drought and climate change
the increasing concentration of a harmbul substance in organisms at higher hrophic? levels in a food chain or food web
the total of the variety of organisms in the biosphere also called biological diversity
sum total of all the different forms of genetic informationcarried by a particular pieces or by organisms on Earth
total amount of functioning ecosystem need to both provide the resources and human population uses and to absorbe the waters that population generates
what are two scientivic uses of radioactive isotopes
geologist determine age by analyzing the isotopes
What is the relationshipbetween catalysts and enzymes
an enzymes is a type of catalysts they both speed up chemical reaction
process that releases energy by breaking down glucose and other food molecules in the presence of exygen
first set of reactions in cellular respiratin is which molecule of glucose is boken into tow molicules of pyruvic acid
second stage of cellulur respiration in which pyruns?? acid is broken down into carbon dioxide in a series of energy extracting reaction
funumental concept of biology that states that all living things are composed of cells that cells are the basic units of structure and function in living fthings and that new cells are prduced from existing cells
domain consisting of all organisms that have a sucleus include protists plants fungi and animals

cell organelle consisting of RNA and protien found throughout the cytoplasm in a cell the sit of protein synthesis
internal membrane system found in eukaryotic cells place where lipid components of the cellmembrane after assembled
organelle in cells that modifies and packaes proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell
organelle found in cells of plants and some other organisms that caputres the energy from the sunlight and converts it into energy
cell organclic??? that converts the chemical energy stroed in food into compund that are more convenient for cells to use
process by which particles tend to move from an area where they are more concentrated to an area where they are lsess concentrated
process of diffusion in which molecules pass across the membrane through cell membrane channels
