Curated OER
Trophic Ecology of Humans
students analyze the place of humans among the tropic levels by observing what we eat. They calculate the caloric content of several foods commonly eaten by humans and calculate the total energy cost to grow, process, transport, store...

The Interdependence of Birds and the Great Salt Lake Ecosystem
Tenth graders participate in the "Checks and Balances" game. This game lets them experience the interdependence of oragnisms specific to the Great Salt Lake. They recieved informaton about food chains, food webs, trophic levels various...

Lesson 4: Gorongosa's Food Webs
Who eats who in the savannas of Africa? Explore trophic levels with part four of an eight-part series of lessons focused around Gorongosa National Park. After young explorers identify animals using trailcam images, they construct a food...

Regents High School Examination: Living Environment 2010
This exam touches upon every topic within the typical first year biology course.. A broad variety of question styles give high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is...
Curated OER
it's Lonely At The Top
Students explore the differnences between food producers in food webs and food consumers in food chains. Behavioral choices of primary and secondary consumers such as herbivores, vegetarians, carnivors, and omnivors are analyzed.
Curated OER
Trophic Ecology of Humans
Students analyze the trophic level of humans by first calculating the kilocalories in own their lunch. They then calulate the kilocalories in a wide variety of foods found in grocery stores and compare the kilocalories needed to acquire...
Curated OER
Entering the Twilight Zone
Students describe major features of cold-seep communities and the process of chemosynthesis as it relates to organisms in each habitat. In this deep-sea habitats lesson, students study the categorization of ocean habitats...
Curated OER
A Tale of Two Reactors
Tenth graders role-play as members of the food chain. Sticky tables acting as polluting factors are introduced and members of different trophic levels suffer varying degrees of damage due to those pollutants.

Trophic Relationships, Cycling of Chemicals, Human Impact on Ecosystems and Conservation
Students explore how the energy flow through a system is related to trophic levels. They investigate how organisms affect the cycling of elements and water through the biosphere. Students participate in lab activities to observe ways...
Curated OER
Aquatic Ecosystem Exploration
Learners visit a local stream, pond, creek, or river and collect macroinvertebrates. They sort macroinvertebrates and identify each species using a dichotomous key. Students decide on trophic levels and construct a possible food web for...

Identifying trophic levels and the skeletal system through Owl Pellets
Students identify a food chain sequence. They compare, identify, and record the rodent skeletal parts to a rodent skeletal diagram. Students construct a rodent skeleton from the skeletal parts found in the pellet. They are given the...

Secrets of the Ocean Realm - Survival in the Sea
Middle schoolers determine the sequential links in a marine food chain and identify the roles that various organisms play in this chain. Students develop charts as visual aids for illustrating marine food chains.
