• Ecology and Physiology

Ecology Power Standards

• 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.

Ecology Power Standards Explanation

• 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?

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

  ecosystem.

What are food chains?

• Owl
• Mouse
• Grasshopper
• Grass

10
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.

Anatomy and Physiology Power Standards

• 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 bodys 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.

12
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.

13
Anatomy and Physiology Power Standards Explanation

• 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 bodys 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.

• For the standards you do not understand, research
  the terms and write an explanation of one
  standard in your own words.
