12-6 Class Agenda
1. Quiz scores
2. Make sure that you put your “Cycles of Matter” handout
(yesterdays assignment) in your Interactive Notebook.
3. Take notes and complete the Energy Pyramid handout
from the PowerPoint
4. Honors-Think Pair Share CER 30 minutes of Videos
5. Last Quiz of semester tomorrow—Energy Pyramid.
NOTES: Energy Transfer in
an Ecosystem
Reminder—This Friday December 9th during lunch is
the last day to retake or take quizzes/tests
10% Rule of the Energy Pyramid
Trophic Levels of the Energy Pyramid
Take notes on Energy Transfer in the
Energy Pyramid
Follow the PowerPoint to fill in your “A
Pyramid of Energy: Energy Transfer in an
Ecosystem “handout for today
What you need to know about Energy
Energy can be neither
created nor be
destroyed; however, it
can change from one
form to another.
THE SUN
Its’ energy continously bombards our planet. Some is deflected by our atmosphere, some hits the earth and bounces back out, some is
trapped via our Greenhouse, and some is captured by Autotrophs during Photosynthesis
• The sun is the ultimate source of energy for all living organisms
• The sun provides energy directlyto producers and indirectly to herbivores, omnivores and carnivores.
• As you go up the food chain/energy pyramid, the amount of available energy decreasesbecause you are getting further away from the original source of energy, the sun.
THE SUNIn the following slides which correspond with your yellow handout title “A Pyramid of Energy: Energy Transfer in an Ecosystem. We will follow how the Sun’s energy is trapped during Photosynthesis and how that energy is lost as it travels up the Energy Pyramid. We will use in this example the Unit of 1000
PRIMARY (1st) CONSUMERThe tomato hornworm loves tomatoes. When it eats the
tomato, it only receives the energy stored: 100 UNITS. Of the 100 units of ENERGY IN, 90 units are used to power the worm’s daily activities and much of that energy is lost to the
activities & surroundings. How much of the original energy is STORED?
SECONDARY (2nd) CONSUMERA Carolina Wren is flying up above and makes a tasty meal out of the hornworm, getting the 10 units of stored energy. Of the 10 units of ENERGY IN, 9 units are used to power the wren’s daily activities and much of that energy is lost to the
activities & surroundings. How much of the original energy is STORED?
