About Trophic Levels: Grazer vs. predator Virtual Lab Simulation

From photosynthesis to apex predator, get ready for a Labster simulation outside of the lab. In this short simulation, you will explore the different trophic levels and understand a zebra’s place in the food web.

Explore trophic levels in an ecosystem

Receive immediate feedback upon exploring food webs and trophic levels. The mission is simple: help a zebra to its feeding ground. To do this, you will have to hide a crocodile in a food chain, place an elephant in a food trophic pyramid and help a lion to place parasites in a food web.

An academic safari

By the end of this simulation, you will explain the different chains within a food web and relate them to a trophic pyramid. Understand concepts such as heterotroph, mixotroph, and autotroph and use them to explain certain behaviors in the different levels of a trophic pyramid.

Will you be able to safely guide the zebra across a crocodile-filled river?

Get Started Now

Experience first-hand how energy is transferred within a food web and between trophic levels. In this simulation, you will guide a zebra towards a feeding ground by interacting with organisms in different trophic levels.

Techniques in Lab

  • Food web
  • Food chain
  • Trophic pyramid

Learning Objectives

At the end of this simulation, you will be able to…

  • Define trophic levels, food webs and ecological pyramids
  • Elaborate on definitions of autotrophic, heterotrophic and mixotrophic organisms
  • Differentiate between food chains and food webs
  • Explain how energy flows between different trophic levels and how this impacts ecosystem structure
  • Predict how pests and parasites fit into trophic systems
