Description:
Brief review of trophic levels thus far and
assessment work that can be used as class
work, quiz, or informal assessment.
Goals:
•Describe the concept of the trophic levels.
•Identify the roles of producers, consumers, and
decomposers.
•Define ecological pyramid and explain its
relationship to energy in the ecosystem.
•Distinguish between food chains and webs.
Objectives: Day 5
•Review trophic levels and organism roles found
on the pyramid.
•Assess our understanding of Trophic Levels
this far.
Warm - Up
Q = Explain what the “Trophic Pyramid” is
used for.
A = It shows the flow of energy and nutrients
through the ecosystem based no the type of
organism niches.

Food Chains
 Food Chains = Sequence of energy
being transferred from one organism to
another.
 Trophic Levels = each step of energy
transfer

Review and Assessment
Guide
This assessment guide will help us understand
our level of understanding this far. We have
covered the trophic pyramid and its levels and
organism roles.
Since this is an assessment it is individual work.
