食物网：了解营养水平之间的互动

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

首先，您将学习如何在食物网中传递能量，以及在自上而下和自下而上的营养级联过程中，每个营养水平如何相互作用。您还将测量外星人的​​呼吸并计算其能量需求。

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 asses 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?
