Ecology Exam Part 2 - Review

True and False
 * Biological magnification(bioaccumulation) vs biological control
 * Edge effect
 * Effect of excess fertilizer like phosphate or nitrates at beginning vs end of eutrophication
 * Mimicry vs camouflage
 * Chemicals taken in by autotrophs vs heterotrophs-remember that plants get everything except CO2 and O2 from the SOIL; heterotrophs must consume all except the O2
 * Which cycles are involved with the air vs land based only
 * Know the concept of carrying capacity as related to limiting factors and bioitc potential
 * Invasive species (ex: Loosestrife, Asian crabs, Milfoil) in Maine

Multiple choice
 * Red tide- cause, organisms effected, etc
 * Causes of species extinction and which is the major one
 * How were Carson and Darwin each involved with ecology
 * Examples of biological control
 * Biodegradable/defined event in landfill- requirements
 * Types (3) of biodiversity effecting endangered species
 * Zones/range of tolerance for an organism-graphic interpretation
 * Mammals that hibernate in Maine
 * Placing examples of adaptations in the right category (physiological, behavior, morphological)
 * results of burning the rainforest
 * The Nitrogen cycle processes-pick the right event to go with the process
 * Long term nutrient cycles- which elements we studied can become longterm

Fill-in the blank/short answer
 * Good and bad of ozone
 * Cause, results, consequences of greenhouse effect (beyond the normal effect which we need to keep our earth warm). Human activity that makes worse; economic impact
 * Ways to reduce personal carbon footprint
 * Definition and Connection of global dimming to global warming
 * Biodegradable vs recyclable
 * connection of Oxygen and carbon cycles
 * biological processes involved in landfills (decomposition being most important)
 * economic impacts of climate change
 * explain adaptation(noun) vs. becoming adapted (verb) in individuals vs populations

Matching
 * Various chemicals involved in pollution problems(match the chemical to the major problem it causes: PO4; DDE; CFC’s; SO2; CO2
 * root adaptations to environmental conditions that favor each

Lists
 * Energy resources and problems with them vs those causing least problems.
 * Adv. vs disadv. of the resources
 * Reasons why biodiversity is important

Combination/application questions
 * How fertilizer leads to eutrophication- explain the role of Oxygen, temperature, algae, phosphate/phosphorous and decomposers
 * How essential elements (C,H,O,N,P,S) are cycled through both abiotic and biotic parts of an ecosystem and processes involved
