Energy Pyramid

  • Top predator
  • Secondary consumer
  • Primary consumer
  • Producers/autotrophs
trophic levels
Trophic Levels
  • Trophic levels -hierarchical levels in an ecosystem
  • always start at the bottom of the energy pyramid with trophic level & count upward

Trophic levels are DIFFERENT from consumer levels!!

  • density-dependent factors are______
test taking strategies
Test Taking Strategies
  • does the question say “best,”“most correct”“not,” or “all”bold? PAY ATTENTION!!!!
  • You may not know what the answer IS, but you may know which choices are NOT the answer!
  • Choose an answer that answers the question!
  • If answers have a “,”“and:”BOTH statements before and after the “,”“and” must be correctfor the statement to be the answer!
