Levels of Ecology
What is the smallest level of ecology?
Species
Only ___% of energy is passed up each trophic level.
10
Living things that do photosynthesis are
Producers/Plants/Autotrophs
Which variable is the one you change in an experiment?
IV
DV changes too, but it's the effect
The sun powers this cycle.
Water
A group of squirrels, blue jays, and oak trees would be this level
Community
Which trophic level has the most energy?
Producers
Which process makes glucose?
ATP?
Glucose - Photosynthesis
ATP - Cell Respiration
What is a controlled variable?
Something you keep constant
Photosynthesis and Cell Respiration directly impact this cycle.
Carbon
A tropical rain forest is an example of this level
Biome
Draw a food chain with these species:
zebra, lion, grass
grass -> zebra -> lion
Reactants of Photosynthesis
Carbon Dioxide
Water
Sunlight
This was our independent variable in the yeast respiration lab.
Type of Sugar
Warm vapor rises, gets cold, and forms clouds is this process.
Condensation
Name 3 abiotic factors
Rain, sunlight, temperature, soil quality, wind, terrain
A hawk eats a snake that eats a mouse that ate a berry. The hawk is what trophic level?
Tertiary consumer
CR: Mitochondria
P: Chloroplast
This was the IV in the elodea lab.
Light or Dark Environment
The evaporation of water through plants is called this.
Transpiration.
What are the six levels of ecology, in order from smallest to biggest?
SPCEBB
What happens to the 90% of energy not passed on?
Used by living thing and released as HEAT
Write the equations for photosynthesis and cell respiration.
P: C+W+sun -> G+O
CR: G+O -> C+W+atp
In a climatograph, what kind of graph is used for temperature? For precipitation?
Temp = Line
Precip = Bar
Bacteria convert Nitrogen from the atmosphere into usable nitrogen for plants during this process.
Nitrogen Fixation
