Which of these is NOT an aspect of wildlife conservation? - ANS ✔✔Reducing genetic variation
Mutation results in the loss of genetic variation in a population (TRUE/FALSE) - ANS ✔✔False
A group of interacting individuals of the same species living in a given area in a given time is
called: - ANS ✔✔Population
Fertility is the actual number of surviving offspring produced by a population (TRUE/ FALSE) -
ANS ✔✔False
Which of the below are characteristic of r-selected life histories? - ANS ✔✔Many offspring &
low investment in young
The processes through which ecosystems and their biota benefit humans are called: - ANS
✔✔Ecosystem services
Autotrophs are the rarest organisms in the Pyramid of numbers/biomass (TRUE/FALSE) - ANS
✔✔False
Disruptions (human additions) to the _______ cycle(s) can cause harmful algal blooms in water
bodies - ANS ✔✔Nitrogen & Phosphorus
Predictions are the expected outcomes of a test given a hypothesis is true (TRUE/FALSE) - ANS

, In the taxonomic classification tree, class is a higher level of classification than phylum
(TRUE/FALSE) - ANS ✔✔False
Genes are found on structures in every cell called - ANS ✔✔Chromosomes
Biogeochemical cycles: - ANS ✔✔represent the movement of nutrients from the non-living
portions of the ecosystem to the living and back again & include cycles such as phosphorous,
water, and nitrogen

Hypothesis development is the first step in the scientific method. (TRUE/FALSE) - ANS ✔✔False
Most of our conservation efforts are focused on r-selected species. (TRUE/FALSE) - ANS
✔✔False
Would elephants best be characterized as r-selected or K-selected? - ANS ✔✔K selected
If/then statements are a part of which step in the scientific method? - ANS ✔✔Prediction
In a highly variable habitat where conditions change quickly (perhaps due to disturbance),
which strategy, r or K would be expected to be more successful? - ANS ✔✔r - selected species
would be more successful in a highly variable habitat.

occurred with the reintroduction of wolves to Yellowstone: - ANS ✔✔decrease in elk
population, increase in berry bush production, increase in grizzly population
