autotroph
What level does all energy eventually flow to?
Decomposer
What type survivorship curve would quality over quantity be associated with?
Type 1
What cycle has their atmospheric stage "fixed" and what is this called?
Nitrogen fixation
Sand Tiger Shark
K
What is the equation for Primary Productivity?
GPP-R=NPP
True or False. Can one species inhabit multiple trophic levels at the same time? Explain your answer
True
Which cycle(s) have more than one major source or sink? What are the sources?
water and carbon
water- fw and sw/glaciers and oceans
carbon- forest and ocean
What is the terminology that all 4 cycles are categorized in
biogeochemical
quantity over quality
r
What biomes would have the highest NPP? Name two.
Swamps, marshes, tropical rainforests, estuaries
The ten percent rule approximates how much energy each trophic level gains. How is energy lost?
Movement, respiration, reproduction, etc
What occupies a higher trophic level. Zebra or Venus Fly Trap?
VFT
What cycle is associated with changes in states of matter
water
multiple reproductive events
K
If there is 55 million kcal worth of energy in the secondary consumers how much did we start with
5,500,000,000
Explain why a food web is a better way to show ecosystem interactions than a trophic pyramid or food chain
insert good answer here
If a population has exceeded this then they will see a significant loss in numbers
carrying capacity
When nutrients are pulled into plant roots what is this called? What elements does this mainly happen with?
Nitrogen fixation
Nitrogen, phosphorous, and water
Sea turtle
A little bit of both, treat the k and r as a spectrum.
