Reading Questions
Vocabulary Review
• Make sure you review the following terms
from 7th & 8th grade:
– Energy
– Heat
– Energy Transfer
– Heterotrophs
– Autotrophs
Vocabulary
Use the reading from last night to define the
following terms:
– Trophic Levels
Notes
• Organisms use energy to:
– Power life processes
• Reproduce
• Survive
– Build more body tissue
• Grow
• Heal
• Store energy (only about 10% of total energy
consumption)
Notes
• Only about 10% of energy of one step of the
food chain is stored in the next step of the
food chain.
• The majority of the energy is used by the
organism or released to the environment
(_______ Energy).
Notes
• Energy Pyramids show the loss of energy as
you step through a food chain.
• See figure on page 44.
• Heterotrophs (consumers) are found in all
levels of an energy pyramid.
• The first trophic level is always occupied by
autotrophs (producers).
Notes
• Top paragraph on page 47.
– Organisms must balance the amount of energy
they use to get food with the amount of energy
they gain from the food. They have to decide if
the prize is worth the effort.
Unit Project
• Review and discuss the requirements of the
Unit Project.
Wednesday Objective
• I will explain how:
– energy enters,
– is used,
– is transferred
– and is lost
as it moves through organisms in an ecosystem.
Homework
• Take the quiz on Mastery Connect.
