Here you have an useful "prezi", specially prepared for students (2 ESO, Natural Sciences) to study the unit about "Ecology and ecosystems". 

These are the topics:

- Ecology.

- Ecosystems.

- Biotic and abiotic components.

- Ecological levels of organization.

- Flow of energy and food: producers, consumers and decomposers.

- Food chains and food webs.

Enjoy it!
