Question
Chapter 57.1, Problem 1R
Summary Introduction
To review:
Whether an ecologist conducts an ecosystem science by measuring the species’ number in an ecosystem.
Introduction:
The ecosystem science is the branch of ecology in which the nutrient flow and energy transfer among the different communities can be observed. One community acts as a predator, whose presence is interdepend upon the presence of its prey. The trees act as the primary source of energy and plays an important role in establishing a community in an area.

Why are models useful to understand ecological systems?
Group of answer choices
They allow for investigation of scenarios that do not currently exist
They can be manipulated
They are simplified representations of ecological systems
A student is observing a pond which
includes the following:
• 2 frogs
• 5 ducks
• Several species of deciduous
trees
• Several large rocks
She identified these observations as a
community. What is wrong with this
identification?
This would be a population
since she is looking at different
species at the pond.
