CELL PHONES FUNCTION Why do we have a Cell phone system? Structures Behavior Contribution to Function What part is What does the How does the part help contribute to its involved? part do? function?Interconnection: Describe how the different structures work together to perform its function/s.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Systems have BFS…. IC• 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

The EcosystemAll the living and nonliving things thatinteract in a particular area make upan ecosystem. 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 place where an organism lives and that provides the things theorganism needs is called its habitat. Terrestrial Habitats Freshwater Habitats Image source: http://www.bbc.co.uk/nature/habitats Marine Habitats
A species is a group of organismsthat are physically similar andcan reproduce with each other toproduce fertile offspring.All the members of one speciesin a particular area are referredto as a population.All the different populations thatlive together in an area make upa community.

The living parts of an ecosystem are called biotic factors.The nonliving parts of anecosystem are called abioticfactors.Abiotic factors includewater, sunlight, oxygen, temperature, and soil. Image source : http://en.wikinoticia.com/
The biotic community and abiotic factors together form anecosystem. Image source: exploringnature.org 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.
