 Objective:
To explain the transfer of
energy in ecosystems and the concepts
of food chains, food webs, and trophic
levels through a short film.
 Prior
experience: None.
Highschool Biology 5.02
• Analyze the flow of energy and the cycling of
matter in the ecosystem. Relationship of the
carbon cycle to photosynthesis and respiration.
– Trophic levels - direction and efficiency of energy
transfer.
– Analyze food chains, food webs, and energy pyramids
for direction and efficiency of energy transfer.
Middle School - 8th Grade 3.04
• Describe how terrestrial and aquatic food webs
are interconnected. –
–
–
–
Food webs share similar properties.
Food webs are highly connected and easily disturbed
Food webs interact with one another
The level of toxins in an organism can be increased up the
levels of a food web causing biomagnification.

 Evaluation questions at the end reinforce
learning.
 Basic concepts and vocabulary research in a
variety of Middle and High School textbooks to
correspond to NCSCOS
 Free
PowerPoint conversion software had
limitations
