Modeling Trophic Cascades
In the ecological game of who eats who, one small change can have a big impact! Individuals create food chains in an array of ecosystems, then determine what happens to organisms in the chain when one organism changes its feeding...

Community Ecology
Chart ecological community interactions and answer questions about niche, defenses, trophic structure, and succession. This community ecology worksheet provides a general overview of the interactions that occur among organisms that share...
Biology Junction
Ecology
Psychologists study human relationships while ecologist study relationships between organisms in the environment. An introduction to ecology and the related vocabulary benefits scholars as they progress through the presentation and...
Curated OER
Ecology
For use early in the year with your ecology class, this collection of slides introduces viewers to cycles in nature and relationships between organisms. There is a food web diagram, but the presentation is incomplete without any diagrams...
Curated OER
Trophic Pyramids and Levels
The bulk of this lesson involves the construction of both an aquatic and a terrestrial ecosystem in which to observe trophic relationships. Detailed directions are provided, as well as discussion questions, and assessment activities....
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...

Food Webs, Energy Flow, Carbon Cycle, and Trophic Pyramids
The reintroduction of a species to an area doesn't always go as expected. Scholars learn about the reintroduction of wolves into Yellowstone National Park with a video, reading, and discussion questions. They complete a hands-on activity...
Curated OER
Ecology
In this ecology worksheet learners complete a crossword puzzle that incorporates all of the ecological vocabulary in the word puzzle.
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...
Chicago Botanic Garden
Leaf Litter Ecology Lab
Some organisms spend their entire lives in leaf litter. The third in a series of six is a great lesson exploring the community of leaf litter. Groups gather and then spread leaf litter over white paper and remove leaves/twigs while...

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...
Curated OER
Ecological Pyramids
Students apply the ecological pyramids of numbers and biomass with an activity using topographic maps. For this trophic level lesson, students work in groups using a topographic map to determine the number of organisms that can live in...
Curated OER
Ecology and The Endangered Species Act
Young scholars listen to a lecture about the basics of Ecology. They take a field trip in which they observe a specific organism and their characteristics.

Everybody Needs a Little Sunshine
Three activities introduce upper elementary ecologists to photosynthesis and food webs. In the first, an experiment is set up to determine how plants respond to different types of light. In the second, they connect organism cards with...

Building Ecological Pyramids
Looking for a fresh take on traditional food/energy pyramids? Conduct an innovative activity where pupils build their own! The lesson uses research data from Gorongosa National Park in Mozambique for a real-life safari touch. Scholars...
Howard Hughes Medical Institute
Exploring Trophic Cascades
What happens when the top predator on an ecosystem disappears? Scholars explore this idea through an introduction example and four case studies. They learn to analyze the importance of every member in a food pyramid to come to their...

Sample Midyear Examination (Chemistry and Biology)
A 12-page midterm exam sample can be given to young scientists in preparation for an exam. This particular installment is geared toward a class that delves into both ecology and chemistry concepts. There is no way to separate the 50...

Principles of Ecology
For this ecology worksheet, students will review 10 vocabulary words associated with the basic principles of ecology. This worksheet has 10 fill in the blank questions.
Curated OER
Principles of Ecology
In this ecology worksheet, students will fill in a graphic organizer showing the relationship organisms have with their environments and with each other. This includes biotic and abiotic factors, tropic levels, and ecological pyramids....
Curated OER
Food Webs
Students recognize interdependence in a food web by using yarn and notecards to create a food web and discussing what would happen if one of the organisms from a certain trophic level is removed.
Curated OER
Ecosystems - Plants and Animals Together
Students study the biotic and abiotic factors of an environment. In this exploratory lesson students examine the different trophic levels and how organisms are connected.

Activity 1: Please Pass the Energy, Food Webs in the Upper Ocean and Hydrothermal Vent Communities
Learners create food webs for two different ocean communities. They are given cards showing organisms from the surface of the ocean. They arrange them in order of who eats whom. After this class activity, students create a food web for...
Biology Junction
Energy Flow in an Ecosystem
Every living thing requires a food source, thus the interconnections in ecosystems become complex. Scholars learn about these interconnections in a presentation on energy flow. It starts with the sun and moves through many different...
Curated OER
Aquatic Ecosystem Exploration
Students 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...
