BIO-114 Exam 1 Review Questions and
Correct Answers
Ecosystem ✅the sum of all organisms living in a given area and the abiotic factors
they interact with
First law of thermodynamics ✅energy cannot be created or destroyed, can only be
transferred or transformed
Second law of thermodynamics ✅Every exchange of energy increases the entropy of
the universe, meaning that energy can only flow through ecosystems instead of cycling
through them for a long time
law of conservation of mass ✅Matter cannot be created or destroyed just like energy
Primary producers ✅the trophic level that supports all others, this is made up of
photosynthetic organisms called autotrophs. these use light to create sugars, organic
compounds and oxygen. (plants)
Primary consumers ✅Herbivores, the organisms that eat the producers
Secondary consumers ✅carnivores, these eat the primary consumers (herbivores)
tertiary consumer ✅these are the carnivores that eat other carnivores, consuming the
secondary consumers
Detrivores/decomposers ✅consumers who get their energy from consuming detritus
detritus ✅organic matter that is not alive this includes dead organisms, feces, fallen
leaves, etc. These are usually prokaryotes and fungi
Primary production ✅the amount of light energy that autotrophs convert into chemical
energy
Gross primary production (GPP) ✅the amount of light that is converted into the
chemical energy used in organic molecules
Net primary production (NPP) ✅NPP=GPP-Ra this represents the amount of chemical
energy being stored in the ecosystem that can be used by consumers
