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.

3. 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?

4. 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

5. Big Idea:Ecology: Living and nonliving factors both make-up an ecosystem.
Food chains and Food webs-flow of energy in an ecosystem.

6. Carbon Cycle

7. The Nitrogen Cycle

8. Oxygen Cycle

9. 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 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.

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 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.

17. Self-Assessment of Understanding
Which standards do you understand? (List them below)
Which standards don’t 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.
