Exam 4: Ecosystems and Nutrient Cycling Engineering Earth

The principal of limiting factors states that the survival,growth,and _______ of a species in an ecosystem are determined by the critical resource in least supply.

Refer to the figure below.Describe ways that scientists attempted to design Biosphere 2 to minimize the effects of limiting factors and help keep organisms within their zone of optimum range.

Consider the following scenario: A plant grows in the soil and is eventually eaten by a rabbit.The rabbit is eaten by a hawk.The hawk becomes ill,dies,and falls to the ground.Fungi and bacteria decompose the hawk.How is this scenario an example of both matter cycling and energy flow?
