Atmosphere
The Atmosphere is the gases (Air) that is
surrounding us.
Biosphere
Biosphere is all the living this that is
surrounding us. Including Trees and Plants.
Hydrosphere
Hydrosphere is the part of the Earth
where there is water.
Geosphere
Geosphere is land and all the small minerals.
Sunlight
This is probably the most important need for
all living organisms, because it is the source of
all energy. It also provides heat for plants and animals
Water is the medium in which living cells and tissue
work. Water is also a living environment for many
plants and animals
Air
Air is made up of several gases, but the two mos
t important gases are Oxygen and Carbon dioxide.
Without oxygen, animals will die, and without
carbon dioxide, plants cannot survive.
Food
Living things need energy for function. Energy is needed
to grow, reproduce, move, and to work. Think of what will
happen if you stayed for three days without food.
The Earth’s Spheres Biosphere, Geosphere,
Atmosphere and Hydrosphere all work
together to create an ecosystem, including
Forest, River, Grassland, Tundra, Desert and
Taiga. These ecosystems are all made up by the
Earth’s Spheres.
