question 64

Multiple Choice

Suppose you are studying the nitrogen cycling in a pond ecosystem over the course of a month.While you are collecting data,a flock of 100 migrating Canada geese lands and spends the night.How could you quantify the effect of this event on the pond's nitrogen cycling?

• A)Find out how much nitrogen is consumed in plant material by a Canada goose over about a 12-hour period,and add that amount to the total nitrogen.
• B)Find out how much nitrogen is eliminated by a Canada goose over about a 12-hour period,and subtract that amount from the total nitrogen in the ecosystem.
• C)Find out how much nitrogen is consumed and eliminated by a Canada goose over about a 12-hour period,and record the net value of nitrogen associated with the goose visitation.
• D)Do nothing.The Canada geese visitation to the lake would have a negligible impact on the nitrogen budget of the pond.
