Unit 1:Eco Footprint
a hypothesis that has been repeatedly tested and confirmed by multiple groups of researchers and has reached wide acceptance
Theory
nonliving things
abiotic
precipitation high in sulfuric acid and nitric acid from reactions between water vapor and sulfur and nitrogen oxides in the atmosphere; also known as acid rain
Acid rain/precipitation
limiting resource
anthropogenic
a state in which inputs equal outputs, so that the system is not changing over time
steady state
habitat that occurs where two different communities come together, typically forming an abrupt transition, such as where a grassy field meets a forest
edge habitat
a plant that lives only one season
annual
Coral bleaching
Greenhouse gasses
energy that comes from the movement of water driven by the gravitational pull of the moon
tidal energy
the predictable replacement of one group of species by another group of species over time
ecological succession
a permeable layer of rock and sediment that contains groundwater
aquifer
the storage of water in a reservoir behind a dam
the storage of water in a reservoir behind a dam
an experiment that exposes organisms to an environmental hazard for a short duration adaptation a trait that improves an individual’s fitness
acute study
a chemical that causes cancer
carcinogen
Genetic Drift
the physical law stating that when energy is transformed, the quantity of energy remains the same, but its ability to do work diminishes
second law of thermodynamics
a study that exposes organisms to different amounts of a chemical and then observes a variety of possible responses, including mortality or changes in behavior or reproduction
dose-response study
the increase in chemical concentration in animal tissues as the chemical moves up the food chain
biomagnification
Gross Domestic Product (GDP)
