11.1 Energy Transfer Flashcards
how is energy tranfered?
it in transferred through photosynthesis and cellular respiration.
what are two sources of energy
sunlight and chemicals
WHat are the two process to convert energy
photosynthesis and chemosynthesis
Products and reactants for photosynthesis
sunlight+ CO2+H2O= O2+glucose
how do heterotrophs turn the glucose they get from plants into energy
cellular respiration
what are the products and reactants of cellular respiration
glucose+O2=CO2+H2O+energy
how much energy can be transferred between trophic levels.
10%
how do we measure energy
biomass
what are the ways we loose biomass
heat, cellular respiration, and waste
how are energy and biomass pyramids different from the pyramid of numbers
they both get smaller as you go uo but in the numbers one it depends on the size of the organisms in the population that depends on the size of the population.
