Activity 2. Human action on ecosystems

To do this activity divide into groups. Each group will work on a different ecosystem.

  • Aquatic: formed by plants and animals that live in water. Aquatic ecosystems can vary in size from an ocean to a puddle. There are salt water and fresh water aquatic ecosystems.

  • Terrestrial: zones or regions where organisms (animals, plants, etc.) live and develop on the earth or in the air around a terrestrial area.

  • Wetlands: flat areas of land with shallow subterranean water which rises to the surface to form lagoons and swamps at different times.

Activity

Read the text that corresponds to your group. Then, talk about it and with the indications in the file make notes about human action on the ecosystem.

Think about… where humans interfered, modified or what other biotic and abiotic components were altered by their actions

The texts and instructions for each group are:

Look at this concept map which shows the factors in an ecosystem and some of the basic relationships between them.

The misuse of natural resources and ecological disasters damage the balance of any ecosystem and sooner or later the consequences can be devastating.

  • Imagine an escape of toxic gas contaminating the air in a region of the planet. Look at the same map and observe the red highlighted factors which would be affected by a toxic gas leak:

We can go further and say that the remains of contaminated plants and animals could contaminate the soil and water, which would be the end of our imaginary ecosystem.

Now it’s your turn.

  • Each text describes the changes or contamination of a different ecosystem.

To help you, use the program Cmap Tool, specially designed to create concept maps,

If it is not installed in your computer or you need help to use it, look at this tutorial: Cmap for pupils.

Sharing the information

The time has come to show your work to the rest of the class.

Project your concept map onto the digital board and talk about the text you read and the modifications. Don’t forget to explain the modifications. The rest of the class will evaluate you with a co-evaluation table.
