WHAT SHOULD I KNOW ABOUT CHARACTERISTICS OF LIVING THINGS?
What is BIOLOGY?
What are the 8 Characteristics of Living things?
What is an autotroph? A Heterotroph?
What does unicellular and multicellular mean? Be able to give examples of these.
What is the difference between sexual and asexual reproduction?
What is homeostasis? Why is maintaining homeostasis important for living things?
What is metabolism?
What is the smallest unit that can carry out life called?
What are all living things made of?
Which of the following are characteristics of ALL living things --- growth, development, cellular
organization, & movement?
What is an organism?
Name living and non-living parts of the environment
Infer how energy from the sun passes to a cow
What is stimulus? What is a response?
Give examples of adaptations.
What should I know about Scientific method/safety?
A scientist noticed that bacteria weren't growing in some test tubes. Is this observation,
hypothesis, or experimentation?
The scientist suggests that bacteria aren't growing in some test tubes because they aren't getting
the nutrients they need. Is this observation, hypothesis, experimentation, or conclusion?
A scientist adds a different nutrient to half of the test tubes in which he is growing bacteria. Is this
observation, hypothesis, or experimentation?
Define hypothesis.
What is the difference between a control, variable, and a constant?
How does an independent variable differ from a dependent variable?
If new evidence emerges, do theories change?
Are theories supported with some scientific knowledge?
Are theories proved scientific ideas?
For scientists to communication with each other about their data, what do they do with their data?
How do scientists organize data?
Flip over
WHAT SHOULD I KNOW ABOUT ECOLOGY?
What is ecology?
Know how these are related: species; population; community; ecosystem; biome; biosphere;
How is a habitat different from a niche;
What are biotic and abiotic factors?
How is the movement of matter and energy through an ecosystem different?
What are autotrophs? Give examples. What are heterotrophs? Give examples.
What are two ways autotrophs make energy (photosynthesis and chemosynthesis) How are these
different?
What is a resource? A food chain? A food web? How are these related?
What is an herbivore, carnivore, omnivore, detritivore, decomposer?
How do they get their energy? Be able to give examples of each of these.
What is a trophic level? What percentage of energy is passed on from one trophic level to the next?
Be able to identify: autotrophs (producers) and heterotrophs (consumers) in a food web and tell what effect
changes in a population will have on other populations.
What are the 3 types of consumers based on their eating habit?
What should I know about Cycles? Biomes? Human Impact?
What is a biogeochemical cycle? Be able to answer ?’s about the 4 cycles you learned about.
(water, carbon, nitrogen, phosphorus)
What is transpiration & what cycle is it a part of ?
How do these atoms enter and leave the atmosphere, land, water, and cycle through the ecosystem?
In which cycle does the atmosphere NOT play a role?
Which biomolecules are important to living things and which cycles provide the atoms to build these?
What is transpiration? Nitrogen fixation? Denitrification? Evaporation? Condensation?
Precipitation?
Which organisms play a role in these processes?
What are the ways organisms interact in an ecosystem? (Competition, Predation, Symbiosis)
What are some things organisms must compete for?
What is a limiting factor? How does it affect a population?
What is predation? What is a predator? Prey?
What are the 3 kinds of symbiosis? Be able to identify examples of each?
What are some of the negative effects hunting, agriculture, and industrial growth have had on the
environment? What is monoculture? What is the green revolution? The industrial revolution?
How has modern farming changed to be more environmentally friendly?
What are renewable/nonrenewable resources? Give examples.
What are some sources of renewable alternative energy? What benefits/problems do these create?
What services do ecosystems provide for us? What is smog? A pollutant?
What is the difference between a threatened, endangered, and extinct species?
What is biodiversity? How does biodiversity relate to the health of an ecosystem?
What are some ways human activity has reduced biodiversity?
(overhunting; habitat destruction; pollution; invasive species)
What is the Convention on International Trade in Endangered Species Act? Be able to give examples of
“Green” organizations? What is the EPA?
What is the Greenhouse effect? What are some “greenhouse gases”? What is global warming? What is
the cause? What can be done to “fix” this problem?
Compare and contrast the following biomes: tundra, tropical rain forest, taiga, savanna, desert,
temperate deciduous. Describe abiotic & biotic factors for each of the biomes
