Bio1152 Chapter 53 Population Ecology
  1. A             is a group of individuals of a single          living in the same area.
  2. Population          (number of individuals per area or volume) results from           and          of individuals; this may change over time as reflected in the population's             .

  3. A population may exhibit different             patterns, often delineated by              boundaries.

  4. A               curve is a graphic way of representing the data in a life table and can be classified into three general types.

  5. In a closed population (no              and emigration), the rate of population growth can become exponential.

  6. Eventually this growth slows to a           growth when the           capacity (K) of the environment is approached, resulting in a          (S-shaped) curve.

  7. The finite resources available may lead organisms to make trade-offs between           and               , reflected in their       history traits.

  8. The human population increased slowly until about       and then began to grow                , until mid-20th century.

  9. Local populations tend to undergo a              transition from high birth and death rates to low ones as economies develop. The regional growth patterns are reflected in      structure diagrams.

  10. The           capacity of Earth for humans can be estimated by the             footprint of different populations. At more than 6 billion people, the biosphere is already in ecological          .
