3 Study a habitat
It is possible to observe ecosystems physically, mapping out observations to determine the network that exists in a given habitat. These observations provide a valuable baseline for understanding a given ecosystem, making it easier to determine the possible negative factors that might be influencing it.
In this video, we join a group of students who are learning how to classify habitats, in the field. After you watch the video, add a definition of an ‘indicator species’ to your glossary.
