ReviewEnvironmental Biology
Chapters 1 & 2
Mining copper: nonrenewable
Burning coal: nonrenewable
Filling a car with gasoline: nonrenewable
Building wooden furniture: renewable
1. Renewable or nonrenewable
2. Hunter-gatherers, Agricultural Revolution, or Industrial RevolutionOverhunting of large mammals Hunter-gatherers
Growth of cities Industrial revolution
Shift in the use of fossil fuels Industrial revolution
Improved quality of life Industrial revolution
Plants & animals were domesticated
Agricultural revolution
Most of today’s environmental problems began Industrial revolution
1. Gather information2. Consider values3. Explore consequences4. Make a decision
3. Decision-making Model
Is it right to build a dam here?
Ethical/moral
How many jobs will building the dam generate?
Economic
Will the dam provide new leisure activities?
Recreational
4. When building a dam, which values are you considering?
United States Developed
Ethiopia Developing
Britain Developed
Canada developed
5. Developed or Developing Nation?
6 Important because humans depend on other organisms for food and oxygen
Biodiversity
7 Describes the conflict between individuals & society
Tragedy of the
Commons8 Amount of land & ocean
needed to support one personEcological footprint
9 Characterized by the indefinite existence of human populations in a healthy & prosperous condition
Sustainable world
10 The number & variety of species living on Earth
biodiversity
11 Would occur if supply of oil declined & the demand remained the same
Price increases
12 “Tragedy of the Commons” addresses the conflicts with protecting what?
Shared resources
13 Listing both the merits and expenses involved in implementing a particular environmental solution
Cost/benefit analysis
14 Which field of study does NOT contribute to environmental science?
linguistics
Chapter 4
Coral reef: ecosystemVacant lot: ecosystemUtility pole: not an ecosystem
1. Ecosystem or not?
Bacteria inside a person’s body: not a population
People at a football game: POPULATION
All the trees in a forest: not a population
All maple trees in a forest: POPULATION
All animals in a forest: not a population
2. Population or not?
3 The place an organism lives Habitat
4 Made up of the different populations of living things in the same area
Community
5 In order for evolution to occur, what must individuals with a trait that is naturally selected for do?
Reproduce
6 Number of kingdoms 6
7 Converts nitrogen in the air into a form plants can use
bacteria
8 Examples include air, soil & temperature Abiotic
factors9 Members of the same species
living in the same place at the same time
Population
10 Examples include insects, leaves, roots Biotic
factors11 Two kingdoms that contain
organisms that can use energy from the sun to make food
Plants & protists
12 Can organisms adapt to their physical surroundings? Yes
13 Can organisms adapt to other organisms? Yes
14 Process of 2 species changing genetically in response to long term interactions with each other
Coevolution
15 Thick fur on a deer is an example of a what?
Adaptation
16 Important function of bacteria and fungi in an environment
Breakdown dead
organisms17 If an organism has a gene
that protects it from a chemical, it is ____ to that chemcial?
resistant
Chapter 8
Winter storms: density independent
Disease: density dependent
Predators: density dependent
1. Density dependent or density independent?
A predator usually kills and eats its prey
2. How is a predator different from a parasite?
3 The number of individuals of a population per unit area
Density
4 Dramatic growth in a population
Exponential
5 Has the greatest effect on reproductive potential
Reproducing earlier in life
6 May cause their hosts to become more vulnerable to predators
Parasites
7 Determines the carrying capacity of an environment for a particular species
Limiting resource
8 3 main properties used to describe a population
Size, density,
dispersion
9 An organism’s niche & habitat are the same thing
FALSE
Type of Interaction Species A Species B
Mutualism Benefits BenefitsCommensalis
m Benefits Unaffected
Predation Benefits Harmed
Parasitism Benefits Harmed
Competition Harmed harmed
