Suppose you are studying the nitrogen cycling in a pond ecosystem over the course of a year. While you are collecting data, a flock of 100 Canada geese lands and spends the night during a fall migration. What could you do to eliminate error in your study as a result of this event?

#Unit 10. Ecological Principles
  1. Find out how much nitrogen is consumed in plant material by a Canada goose over about a 12-hour period and multiply this number by 100 and add to the total nitrogen in the ecosystem.
  2. Find out how  much nitrogen is  eliminated by a Canada goose over about a 12-hour period and multiply this number by 100 and subtract from the total nitrogen in the ecosystem.
  3. Find out how much nitrogen is consumed and eliminated by a Canada goose over about a 12-hour period and multiply this number by 100; enter this +/-value into the nitrogen budget of the ecosystem.
  4. Do nothing. The Canada geese visitation to the lake would have negligible impact on the nitrogen budget of the pond.
