The document discusses the elements of ecosystems in three types of forests: Mediterranean forests, Atlantic forests, and forests of the Canary Islands. It examines the biotope, biocenosis, and interactions for each forest ecosystem. It also provides information on the ecosphere and biosphere, defining the ecosphere as the area around a star suitable for life and noting Earth and Mars comprise our solar system's ecosphere, and the biosphere as all living things on Earth inhabiting the troposphere, hydrosphere, and upper geosphere.

15. THE ECOSPHERE
• An ecosphere can mean an
imaginary shell of space
surrounding a star where
temperatures are suitable for
life to exist on a planet.
• An example is the ecosphere
of our Solar System.

16. • Our Solar System’s ecosphere is
the imaginary area around the Sun
where temperatures are suitable
for life to exist.
• It encompasses two planets:
Mars and Earth.

17. THE BIOSPHERE
• The biosphere is the collective term for the living organisms that
inhabit our planet. In other words, the living things that live in the
troposphere, the hydrosphere and the upper layer of the
geosphere.
