The Biosphere

1
The Biosphere

• A System of Life on Earth

2
The Biosphere is a System!!

• Write you own definition of a system. (think of
  you journey)
• What do all systems have in common?
• Write at least three-

3
Student Exploration( in your notes)

• Think of a system, _________________
• Draw the system
• Label each part of the system
• Describe how this system is in itself a part of a
  larger system
• Name an even larger system that your system is in.

4
The Biosphere

• The Sun begins the movement of all systems here
  on this Earth
• Write down these points to remember about all
  systems
• Whole is more important than parts
• Parts do not look like the whole
• The health and wellbeing of a system is dependant
  of the parts health and wellbeing

Biosphere- Systems with in systems

• A Definition of the Biosphere
• A Living Sphere that surrounds Earth and its
  parts that supports life in that sphere
• Kilometers high to oceans deep
• We study the biosphere by studying different
  systems with in the Biosphere
• We call those systems the Ecosystems.
• A study of Ecosystems is called Ecology.
• What would a scientist be called, that studies
  an Ecosystem. ______________?????

6
What do Ecologist Study?

• The energy flow within an Ecosystem
• How Matter flows within a Ecosystem.
• Points to remember
• There are systems within system!
• A Ecologist can determine exactly what system
  he will study
• Ecosystems can be large or small
• Example

7
Ecosystems can be as big as the West Desert or as
small as the stuff growing on your Eyelid.
8
What ever the Ecosystem It is connected to
another systems, which is connected to another
systems which is..

• The are systems within systems.
• Therefore, when a Butterfly flaps its wings in
  China, it eventually will effect YOU

9
The Characteristic of all Earths Ecosystems is
that they have

• Examples

• Matter or the stuff everything is made of
• 2.Energy What motivates the matters function
  or flow
• 3. Life Organisms and how they get energy and
  matter to live

10
Science is a system of Knowledge

• To help you understand the 3 characteristics of
  Our Earths Systems Scientist organize Energy
  and Matter as they both journey though the
  different ecosystems models. Drawing the
  Hierarchy of Ecosystems will help you understand.

How Energy flows- the Rules

• All energy moves only one direction
• As energy is transferred, it will loose 90 of
  its energy
• Energy is always conserved
• The main source of all energy on the Earth is Da
  Sun!

12
Energy is transferred through the Ecosystem in
the form of food webs, food chains, food pyrimids.
