Biology Questions and Answers
analysis of incorporated organic
material.
- What do energy pyramids
represent?
Energy pyramids rof available energy in eepresent thach troe amountphic level (^)
of the food chain.
- Into which type of energy
is the light used in
photosynthesis transformed?
The luminophotosynthus energy used inesis is transformed into (^)
chemical energy.
- Can the amount of
available energy in a given
trophic level be larger than
the available energy in inferior
trophic levels? What does that
condition means to the
conformation of the energy
pyramids?
A superior troavailable energy than phic level alwaysinferior tro has lessphic
levels. This is because in each trophic
level only a fractionmaterial of the level below is of the organic
incorporated into the consumers (into
their bodies). The other part iseliminated as waste or is used in the (^)
metabolism as energy source. Therefore
it is nepyramids with invver possible erted conformation,to have energy (^)
i.e., with the tip to the bottom and the
base to thhave superior trope top. It is also not possible tohic levels with a
variable dimension larger than inferior
ones. In every energy pyramid, fthe base to the top, the size of therom
variable dimension decreases.
- What is the gross primary
production of an ecosystem?
How does GPP relate to
photosynthesis?
Gross primary ecosystem, or GPP, is the quantityproduction of an (^) of
organic material fa given period. ound in a given area in
Since only autotropmaterial and photosynthesishs produce organic is the mai (^) n
production process, GPP is a result of
the photosynthesis.
- What are the factors that
for influencing photosynthesis
also interfere with the gross
primary productivity?
Mainly water and light, but also mineral
salts, temperature aare factors that internd carbon fere with tdioxidehe gross (^)
primary productivity.
