ECOLOGICAL SYSTEM
FUNCTIONWhy do we have a Cell phone system?
StructuresWhat part is
involved?
BehaviorWhat does the
part do?
Contribution to FunctionHow does the part help contribute to its
function?
CELL PHONES
Interconnection: Describe how the different structures work together to perform its function/s. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
• Behavior = Role (role of each part)
• Function = Purpose (purpose of the whole system)
• Structure = Parts
• Interconnection – there are links between parts
• Changes – If a part fails to perform, it will affect the whole system

Is the
E-column a Closed System?
Explain.
Organisms live in a specific place within an ecosystem.
An organism obtains food, water, shelter, and other things it needs to live, grow, and reproduce from its surroundings.
The EcosystemAll the living and nonliving things that interact in a particular area make up an ecosystem.
The place where an organism lives and that provides the things the organism needs is called its habitat.

A species is a group of organisms that are physically similar and can reproduce with each other to produce fertile offspring.
All the members of one species in a particular area are referred to as a population.
All the different populations that live together in an area make up a community.

BIOTIC AND ABIOTIC FACTORS
http://www.youtube.com/watch?v=y-wpbhnom70
The living parts of an ecosystem are called biotic factors.
The nonliving parts of an ecosystem are called abiotic factors.
Abiotic factors include water, sunlight, oxygen, temperature, and soil.

Level of Acidity (pH)
The biotic community and abiotic factors together form an ecosystem.
The study of how living things interact with each other and with their environment is called ecology.

Group Brainstorm:
Create a list of biotic and abiotic factors for your assigned chamber.
Share your list to your group mates.
Discuss and make revisions in your list.
Make a list of 5 important things you need to do to sustain your E-column.
Think about what each chamber contributes to the other chambers.
