environmental scienc

9-weeks test

Renewable resource and example can replenish itself within a lifetime, ex: water, trees
Nonrenewable resource and example will eventually run out, ex: coal, oil
Abiotic and give an example nonliving thing, ex: rocks, wind, water
Biotic and give an example living thing, ex: grass, trees, animals
Natural selection occurs in nature; survival of the fittest
Artificial selection humans manipulate genetics to produce what they want
Name and explain the ranges from the chart Optimal range (top; where things are thriving); Zone of physiological stress (downslope); Zone of intolerance (no tolerance for conditions that exist)
Organize the levels from smallest to largest organism, population, community, ecosystem, biosphere
Psuedoscience and give three examples doesn't follow scientific principles, ex: Mind reading, alchemy, astrology, palm reading
What are the steps for the scientific method? 1) Come up with a question, 2) Hypothesis, 3) Experiment, 4) Analysis of the data, 5) Make a conclusion, 6) Determine if the hypothesis is supported
Variable thing that is changed
Experimental group receives the variable
Controlled group is left alone
What are the 3 phases of matter? solid, liquid, gas
blind experiment scientist knows what is going on, the experimental group does not
double blind experiment neither the experimental group nor the scientist knows what is going on
What does the double blind experiment reduce? bias
Voc. Matching
What starts as one population and splits into 2? Divergent evolution
What goes from 2 populations and evolves into 1? Convergent evolution
when two species spend enough time together they start to look like each other Coevolution
When over a long period of time enough mutations take place for a new species to emerge Speciation
Small advantageous mutations that have accumulated over countless generations Evolution
competition occurs within members of the same species Intraspecific competition
competition occurs between two different species interspecific competition
Plays the greatest role in determining an organisms range; too much or too little, animals need specific things critical factor
specific gene traits that control adaptations Inheritance
When both organisms benefit Mutualism
When one organism benefits and the other is neither harmed nor helped commensalism
when one organism benefits and the other is harmed parasitism
nature should exist for its own sake regardless of human needs Ecocentrists
Human centered Anthropocentrists
Biological community and its surrounding physical environment Ecosystem
a specific area where an organism inhabits Niche
Trait that allows a species to survive more easily and reproduce Adaptation
A particular environment where an organism can live Habitat
all conditions that surround living organisms Environment
concepts and ideas from multiple fields of study Interdisciplinary
degradation or an undesired change in soil, air or water that affects the health of living things Pollution
began with a public awakening to threats of pollution and toxic chemicals to humans and other species Modern environmentalism (Rachel Carson)
explores issues ad problems all over the entire world not just a local community Global environmentalism
area that belongs to no individual and is shared by the entire society Commons
the greater the demand for something the higher the price Supply & Demand
does the risk out way the benefit? Is it worth the risk Risk Analysis
measurement of a persons resource use Ecological footprint
when human needs are met so that the population can survive indefinitely sustainability
Write out voc.
Close system nothing enters or leaves the earth in large quantities
Biodiversity the number of different species present in an ecosystem
Developed country High income, higher life span, lower population growth
Developing country Low income, lower life span, higher population growth
