APES Chapter 3 Test QUESTIONS AND
ANSWERS
a particular location on Earth distinguished by its particular mix of interacting
biotic and abiotic components; come in a wide range of sizes, can recycle matter -
ANSWER>>ecosystem
What types of boundaries do ecosystems have - ANSWER>>they don't have any
distinct boundaries
non living things such as sunlight, oxygen, energy - ANSWER>>abiotic factors
living and once living components of an ecosystem, which includes the role the
organisms play; can determine a species success - ANSWER>>biotic factors
more important in aquatic ecosystems - ANSWER>>dissolved oxygen
the most inclusive components of the biotic portion of an ecosystem are -
ANSWER>>producers and consumers
which of the following are biotic-decomposers, energy flow, or producers -
ANSWER>>only living things like decomposers and producers
factors which prevent a community, population, or organisms growing larger. -
ANSWER>>limiting factor
what's a limiting factor in aquatic systems - ANSWER>>phosphate
what's a limiting factor in the tundra - ANSWER>>low temperature
, what are the reactants of photosynthesis - ANSWER>>carbon dioxide and water
with sunlight
what are products of photosynthesis - ANSWER>>glucose and oxygen (a waste
product)
what can photosynthesis also be thought of as - ANSWER>>the conversion of
solar energy (from the sun) into chemical energy (glucose)
what groups of organisms performs photosynthesis - ANSWER>>autotrophs or
producers
what is the greatest ecological contribution of photosynthesis - ANSWER>>the
production of glucose for organisms at the base of any food chain web/chain and
the production of oxygen for aerobic using organisms
what is chemosynthesis - ANSWER>>a few producers (bacteria) can convert
simple compounds from their environment into more complex nutrient
compounds without sunlight
where is a location on earth where chemosynthesis takes place? - ANSWER>>mid-
ocean rift zones
where do rich ecosystems usually develop around - ANSWER>>hydrothermal
vents where bacteria make their own food from the energy in sulfur
involves breaking down food, often in form of glucose to release energy which is
used in living processes - ANSWER>>respiration
reactants of aerobic respiration - ANSWER>>glucose and oxygen
products of aerobic respiration - ANSWER>>carbon dioxide, water, and energy
