Life
How scientists classify organisms
taxonomy
includes all parts on Earth where life exists
Biosphere
the smallest unit of matter
Atom
the group of organisms in an ecosystem that occupy the same level in a food chain/web
trophic level
3 different ways to represent levels of ecological levels
Energy, Biomass pyramid of numbers
three types of biogeochemical processes
Physical and Chemical, Geological, Biological
The 8 general levels of classification of life
Domain, Kingdom, Phylum, Class, Family, Genus, Species
Name the levels of organization of organisms from smallest to largest (4)
population, community, ecosystem, biomes
when two or more atoms combine chemically
molecule
the flow of energy through an ecosystem that includes the diversity of an ecosystem
food web
What are the levels of an ecological pyramids
producers, primary consumers, secondary consumers, and tertiary consumers
What are the main points of the water cycle (draw a diagram?)
precipitation, ground water, evaporation/transpiration, condensation,
water storage in clouds, oceans/lakes, ice and snow
the passing on of DNA and the traits it encodes to offspring
inheritance
three main Earth systems (spheres)
Hydrosphere, Atmosphere, Geosphere
the forces that hold elements together to connect atoms
Chemical bond
All food chains and webs start with
producers
What is the pattern for energy as it goes up the ecological pyramid
only 10 percent of energy is passed on to the next level in the pyramid
What are the main aspects of the Carbon cycle
Atmospheric CO2, diffusion, volcanic activity, burning of fossil fuels, photosynthesis/respiration
inherited advantages passed on through genetics
adaptation
Three main roles of organisms in the Ecosystem
Producers, consumers, decomposers
The process of creating energy from the sun
Photosynthesis
the consumers at the top trophic level
apex consumers
What is the pattern seen with a biomass pyramid
biomass decreases as we move up the biomass pyramid
Needs bacteria to enter the biological sphere
Nitrogen
Steps of the Scientific method
observation, hypothesis, research, experiment, data collection, data analysis, discussion/conclusion
the simple diagram to represent the movement of energy and matter within an ecosystem
Food chain
the chemical process of creating energy from the break down of sugars
cellular respiration
what is the main way a food web can be stable
biodiversity
What are 2 patterns we see with the pyramids of numbers
few organisms the higher up the pyramid or one tree feeds 1000 caterpillars, 100 song birds, 1 hawk
Enters the system by way of weathering and plant uptake, major cause of eutrophication
Phosphorus
