the structures and functions of living the structures and functions of living organisms and their interdependence on organisms and their interdependence on
each other and their environment.each other and their environment.

Organization of Living Things
• Cells• Tissues• Organs• Organ systems• Organisms• Populations
7.12C
What's the Function?• Circulatory
– Transport food & oxygen to cells– Transport waste products from cells
• Respiratory– Provide oxygen to the blood– Remove carbon dioxide from the blood
• Skeletal– Support, protection, and movement
7.12B
What's the Function?• muscular
– Body Movement – Movement of blood and food
• digestive– Break down food to nutrients– Deliver nutrients to circulatory system
• excretory– Remove wastes from the body
including excess water
7.12B
What's the Function?• reproductive
– Pass genetic information to offspring– Continue the species
• integumentary (skin)– Protection– Reduce water loss
• nervous– Process information & send
instructions
7.12B
What's the Function?• endocrine
– control homeostasis– regulate bodily functions like
metabolism– control growth– Control development– reproduction
7.12B
Reproduction
• Inherited traits controlled by _1?_.– Found in _2?_, located on _3?_ found
within the _4?_ of a cell.
• Asexual vs. sexual– Which creates more diversity?
Photosynthesis…Light

Energy Flow through Living organisms..
• Sun producers primary consumers secondary consumers
• Food chains• Food webs…decomposers
7.5C
Texas Food WebWhich of these are producers?
Which of these are primary consumers?
Which of these are secondary consumers?
Which of these are tertiary consumers?

Question• Which organisms are both
secondary and tertiary consumers in this partial desert food web?

Question• Flowers in a vase have enough turgor
pressure to look fresh. If they lose turgor pressure, they become wilted. How is turgor pressure maintained?
A. air is pumped into flowersB. water moves into cellsC. minerals turn to crystalsD. more sugar is producedE. water is pumped out of the
cellsF. more sugar is consumed
B. water moves into cells

Ecosystem Factors
•Biotic–Living
•Plants•Animals•Decomposers
•Abiotic–Non-living
•Water•Soil•Rocks•Air•Light
8.11B
Discussion• Given two organism
that consume the same things in aa forest ecosystem, what would happen to the organisms if a drought caused a major loss of trees?
8.11C
Succession• What is it?
– series of predictable changes in a community that occur over time
– Begins on new land such as a volcanic island– After major event: volcanic eruption, fire
• 2 types– Primary: start with no ecosystem existing; 1st—
pioneer species (lichens & mosses) then grasses, shrubs and finally trees
– Secondary: occur after a disturbance such as farming or logging; regrowth of grasses, shrubs, small then larger trees
7.10C
SuccessionTypes of catastrophes:
volcanic eruption forest fire deforestation land cleared for agriculture

Organism Structures
A dichotomous key to these six species is shown. Complete the missing information for sections 5.a. and 5.b. so that the key is complete for all six species.
7.11A
Organism Structures
Using the dichotomous key, classify an organism that has small or no wings, shorter rear legs, not a horned head and small eyes.
7.11A
Explain the Relationships
• Producer — Consumer
• Predator — Prey• Parasite — Host
8.11A
Organisms & Environmental Change
• Polar bears are dependent on sea ice to hunt seals and to move from one area to another.
• What might happen to the polar bears if global climate change continues?
8.11C
Differentiate between Natural Selection & Selective Breeding
• Both are ways traits are passed from parent to offspring
• Natural Selection – Referred to “survival of the fittest”– Only the most adapted organisms live to pass on
their genes– Peppered moth and air pollution
• Selective Breeding– Human controlled– We physically breed for the traits we WANT in the
offspring– dairy cows
