BI 6.a-Students know biodiversity is the sum total of different kinds
of organisms and is affected by alterations of habitats.
BI.6.b.-Students know how to analyze changes in an ecosystem
resulting from changes in climate, human activity, introduction of
nonnative species, or changes in population size.
BI.6.c.-Students know how fluctuations in population size in an
ecosystem are determined by the relative rates of birth, immigration,
emigration, and death.
BI.6.d.-Students know how water, carbon, and nitrogen cycle
between abiotic resources and organic matter in the ecosystem and
how oxygen cycles through photosynthesis and respiration
BI 6.e-Students know a vital part of an ecosystem is the stability of
its producers and decomposers.

BI 6.a-Biodiversity is total number of different livings things in an
area. Biodiversity is affected by changing habitats.
BI.6.b-Changes in an ecosystem can be caused by changes in
climate, human activity (pollution), introduction of nonnative species
(snakes), or changes in population size (limiting factors).
BI.6.c.-Changes in population size in an ecosystem can be caused
by increased/decreased birth, immigration, emigration, and death
rates.
BI.6.d.-Water, carbon, and nitrogen cycle between abiotic (nonliving)
resources and organic matter in the ecosystem. Oxygen cycles
through photosynthesis (plants) and respiration (animals) in an
ecosystem.
BI 6.e-Producers and decomposers maintain the stability (balance)
of ecosystems. How?
Big Idea:Ecology:Living and nonliving
factors both make-up an ecosystem.
Key Terms:
 Ecology-The study of the interaction
among living things, and between living
things and their environments
 Ecosystem
 Biotic and abiotic factors

Food chains and Food webs-flow of
energy in an ecosystem.

What are food webs?
Food web-is a model that shows the
complex network of feeding relationships
and the flow of energy within an
ecosystem.
 At each link some energy is stored by an
organism and some is lost.


The stability of an ecosystem depends on
the producers.

BI9. a. Students know how the complementary activity of
major body systems provides cells with oxygen and
nutrients and removes toxic waste products such as
carbon dioxide.
BI9. b. Students know how the nervous system mediates
communication between different parts of the body and
the body’s interactions with the environment.
BI9. c. Students know how feedback loops in the
nervous and endocrine systems regulate conditions in
the body.
BI9. d. Students know the functions of the nervous
system and the role of neurons in transmitting
electrochemical impulses.
Big Idea Physiology :The internal environment of
the human body is stable because of multiple
organ systems working together.

The human body is made of different
levels of organization starting with cells
and building up all the way to organ
systems. Organ systems work together
through mechanisms like negative
feedback loops to maintain
homeostasis in the human body.

BI9. a.-Organ systems work together to maintain
homeostasis by providing cells with oxygen and nutrients
,and removes waste products such as carbon dioxide.
BI9. b.-The nervous system is the communication
network different parts of the body. The nervous system
processes the body’s interaction with the environment.
BI9. c. –Feedback loops (nervous system and endocrine
system) maintain stable conditions in the body (temp.)
BI9. d.-The function of the nervous system is to
communicate and control the functions of the body.
Neurons (nerve cells) send messages to and from the
nervous system.
Negative Feedback Loop-Ex.
