Review-Benchmark III
  • Ecology and Physiology

2
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?

Big IdeaEcologyLiving 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

Big IdeaEcology Living and nonliving factors
both make-up an ecosystem.
  • Food chains and Food webs-flow of energy in an
    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.

11
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.

Self-Assessment of Understanding
  • Which standards do you understand? (List them
    below)
  • Which standards dont you understand? (List them
    below)

18
Self-Assessment of Understanding 2
  • For the standards you do not understand, research
    the terms and write an explanation of one
    standard in your own words.
