2- Watch a video and create a mind map where you will display your reflection of the video.
3- Create a series of food chains and food webs using plants and animal from various ecosystems.
4- Use your knowledge to find the best way to stabilize an ecosystem
5- Write and essay about the balance of the chain food of a picture given.

Conclusion
When the students complete all the task they will be able to understand the importance of keeping the balance in the ecosystems and the importance of respect and take care of all the components of the ecosystems. Additionally, they will learn how a chain food work and what are the consequences of removing an specie of the chain food.
Students will develop more responsibility to protect the ecosystems.
