About This Simulation
Help reduce the impact from humans on an aquatic ecosystem on an exoplanet by using your knowledge of trophic cascades in a food web.
Learning Objectives
- Understand food webs
- Explain the differences between different trophic cascades
- Calculate the amount of energy needed for maintenance

Learn More About This Simulation
In this simulation, you will learn about food webs. You will be guided through the different trophic levels of a food web on the exoplanet Astakos IV, while learning about the interactions between different organisms.
Energy transfers in a food web
First, you will learn how energy is transferred in a food web, and how each trophic level interacts, during both top-down and bottom-up trophic cascades. You will also measure the respiration of an alien and calculate its energy needs.
Estimate energy transfer in a food web
You will be presented with an alien food web with grazers, omnivores and predators. By measuring respiration you will estimate the energy used by a central omnivore species. You will also be tasked with assessing the direction of the energy flow through the food web when a trophic cascade is caused by anthropogenic disturbances.
What happens when the main source of energy is removed from a food web?
Through a series of mini games you will help a group of settlers on Astakos IV assess their impact on the local ecosystem. Are you up for the challenge of figuring out how the settlers’ different constructions impact the local food web?

North Dakota State College of Science
“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”
Lecturer in Human Physiology
University of Westminster
"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.
Modesto City Schools
"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."
Wenatchee Valley College
"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”
San José State University
"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."

A Labster virtual lab is an interactive, multimedia assignment that students access right from their computers. Many Labster virtual labs prepare students for success in college by introducing foundational knowledge using multimedia visualizations that make it easier to understand complex concepts. Other Labster virtual labs prepare learners for careers in STEM labs by giving them realistic practice on lab techniques and procedures.
Labster’s virtual lab simulations are created by scientists and designed to maximize engagement and interactivity. Unlike watching a video or reading a textbook, Labster virtual labs are interactive. To make progress, students must think critically and solve a real-world problem. We believe that learning by doing makes STEM stick.
Yes, Labster is compatible with all major LMS (Learning Management Systems) including Blackboard, Canvas, D2L, Moodle, and many others. Students can access Labster like any other assignment. If your institution does not choose an LMS integration, students will log into Labster’s Course Manager once they have an account created. Your institution will decide which is the best access method.
Labster is available for purchase by instructors, faculty, and administrators at education institutions. Purchasing our starter package, Labster Explorer, can be done using a credit card if you are located in the USA, Canada, or Mexico. If you are outside of North America or are choosing a higher plan, please speak with a Labster sales representative. Compare plans.
Labster supports a wide range of STEM courses at the high school, college, and university level across fields in biology, chemistry, physics, and health sciences. You can identify topics for your courses by searching our Content Catalog.
