Section 1: Everything is Connected
Chapter 4 Section 1: Everything is Connected AIM and HW AIM: What
is an ecosystem? How are ecosystems connected?
HW: 1) QUIZ on FRIDAY 2) Complete Active Reading DO NOW You may
have heard the concept that in nature everything is connected. In
your EcoLog answer the following questions: What does this mean?
List 2 examples Everything is connected = EU today the sparrow,
tomorrow it may be you Defining an Ecosystem Ecosystem = all of the
organisms living in an area together with their physical
environment interactions between living and nonliving components of
the environment Ecosystem = I could also define ecosystem as
Defining an Ecosystem Living (biotic) and Nonliving (abiotic)
How do you define living and nonliving factors? Living (biotic)
Nonliving (abiotic) The Eight Life Functions
Definition T Transport movement R Respiration conversion of energy
(ATP) Reproduction produce another Regulation maintain homeostasis
S Synthesis creation of large molecules from small molecules E
Excretion elimination of metabolic waste N Nutrition obtain/make
nutrients G Growth increase in cell size or number Biotic or
Abiotic? Video CLOSURE What does TRRRSENG represent? Biotic vs.
Abiotic Whats More Important?
Groups 1, 2, and 3 (period 1/2) and Groups 1 and 2 (period 5/6) =
List at least 8 biotic factors found in ecosystems. Rank them in
order of importance and be prepared to defend your ranking. Groups
4, 5, and 6 (period 1/2) and Groups 3 and 4 (period 5/6) = List at
least 8 abiotic factors found in ecosystems. Rank them in order of
importance and be prepared to defend your ranking. AIM: How do
scientists organize ecosystems?
AIM and HW AIM: How do scientists organize ecosystems? HW: 1) QUIZ
on FRIDAY 2) Complete Map Skills DO NOW In your EcoLog, describe
how factors in the ecosystem below interact Ecological Organization
- Population
Population = organisms of the same species living together in a
given location Ecological Organization - Community
Community = all of the different populations in a given location
interacting with each other Does not include abiotic factors
Ecological Organization - Ecosystem
Ecosystem = all of the different communities in a given location
interacting with each other Ecological Organization - Biome
Biome = a large region characterized by a specific type of climate
and certain types of plants and animals Ecological Organization -
Biosphere
Biosphere = every living and non-living thing on the planet
(portion of the Earth in which life exists)
