Ecology Test 1 True/False

The flashcards below were created by user kamrunsreno on FreezingBlue Flashcards.

  1. “Why are some species more vulnerable to extinction than others?” is an example of a
    question that would be asked of a functional, applied ecologist.
    False
  2. Ecology differs from other subdisciplines of biology in being exclusively synthetic
    rather than analytic.
    False
  3. The ecology of a single species is called autotrophy.
    False- Its called autecology
  4. An ecosystem includes a biotic assemblage and the abiotic environment.
    True
  5. Epistomology is the ecology of ecosystems and communities.
    • False
    • The study or a theory of the nature and grounds of knowledge especially with reference to its limits and validity
  6. Statistics are used by scientists to prove hypotheses.
    True
  7. Darwin’s concept about evolution occurring by natural selection is a law in ecology and evolutionary biology.
    False-- it's a theory
  8. The Marginal Value Theorem states that organisms should evolve to forage in habitat
    patches until the energy per unit time yielded by the habitat patch falls below that expected from an average patch of habitat.
    Thus, an animal forages in a patch until the rate of food encountered falls below the average of all other patches.
  9. Optimal foraging for food where prey items are very abundant should result in the predator being a specialist.
    True
  10. The “modern synthesis” is an amalgamation of numerous sciences such as genetics, biogeography, embryology, and taxonomy.
    True
  11. Macroevolution is said to occur lead to punctuated equilibria.
    True

    Another mode of evolution is MACROEVOLUTION or evolution by punctuated equilibrium.
  12. Sexual reproduction can be important in the process of evolution by increasing the diversity of genotypes within populations
    • True
    • One way to create new variation in the genotypes is through sexual reproduction and recombination. Consider that meiosis takes the diploid genotype an produces haploid sperm or eggs, and Sexual reproduction creates variation that is the “fuel” for evolution
  13. Energy maximizers are species that can use all the energy that they can obtain
    • True
    • thosewho can use all the energy that they take in. Optimal diet will occur when the animal always takes in the maximum energy per item.
  14. Optimal foraging theory is about decisions only concerning where to search for prey.
    False- also concerns how to spend least amount of energy doing so
  15. Optimal digestive theory uses the same currency of energy per unit time as does optimal foraging theory.
    True
