Questions And All Correct Answers
What are some of the characteristics of r-strategists? - CORRECT ANSWER Have
many small young, little or no parental care, rapid development, long distance
dispersers, early age of first reproduction, poor competitors, short life span, small body
size, live in disturbed habitats, wide fluctuations in population size
What are some of the characteristics of k-strategists? - CORRECT ANSWER few large
young, more parental care, slower development, short distance dispersers, later age of
first reproduction, good competitors, long life span, larger body size, live in stable
habitats, relatively constant population size
Why is temperature important? - CORRECT ANSWER Temperature is critical because
the enzymes that make life possible work at optimal efficiency only in a narrow range of
temperatures
Why is moisture important? - CORRECT ANSWER Moisture is important to terrestrial
organisms because they constantly lose water to the environment through evaporation
or transpiration
Why is sunlight important? - CORRECT ANSWER Areas of the world are warm if they
receive a large amount of sunlight per unit area; they are cold if they receive a small
amount of sunlight per unit area. Earth's shape dictates that regions at or near the
equator receive more sunlight per unit area than regions that are closer to the poles.

deemed fewer than 100 and are only that many heartbeats from extinction
Humans are constantly moving _________ between continents and islands are either
deliberately or accidentally - CORRECT ANSWER species
What are the characteristics of invasive species? - CORRECT ANSWER They are a
pioneer species, have high dispersal rates, and are found in disturbed habitats
Why are invasive species successful? - CORRECT ANSWER there are no diseases,
herbivores, parasites, or predators, they are better competitors than native species
Types of Solid Waste - CORRECT ANSWER Agricultural Waste
Industrial Waste
Municipal Waste
Agricultural Waste - CORRECT ANSWER Animal waste and crop residue; generally
recycled
Industrial Waste - CORRECT ANSWER Generally recycled or stores in private landfills;
mining residue which is stored near mining site
Municipal Waste - CORRECT ANSWER Home and office waste; not a lot recycled
Waste stream - CORRECT ANSWER A steady flow of waste
Recycling - CORRECT ANSWER Processing waste into new products
______ is the most valuable product to recycle - CORRECT ANSWER Aluminum
