GPP → NEP [producers to top predator]
ACRONYM
DEFINITION
Respiration of producers. Biomass/energy used by
producers during metabolism.
Respiration of consumers. Biomass/energy used by
consumers during metabolism.
Biomass/energy created by plants during photosynthesis.
Biomass/energy left over after all respiration (producers
and all consumers) has occurred.
GPP → NSP [producers to primary consumers only]
ACRONYM
DEFINITION
Biomass/energy lost directly to excretion.
Biomass/energy of plants' growth. Biomass/energy
available to be eaten by consumers.
Biomass/energy of primary consumer's growth.
Biomass/energy assimilated into the body tissue of the
primary consumer. Biomass/energy digested.
Biomass/energy ingested by the primary consumer.
Biomass/energy not ingested by the primary consumer.
Biomass/energy of plants' growth. Biomass/energy
available to be eaten by consumers.
Biomass/energy created by plants during photosynthesis.
Respiration of producers. Biomass/energy used by
producers during metabolism.

If the flow of energy in an Arctic ecosystem goes through a simple food chain from seaweeds
to fish to seals to polar bears, then which of the following is TRUE?
a.
Polar bears can provide more food for Eskimos than seals can.
b. The total energy content of the seaweeds is lower than that of the seals.
c.
Polar bear meat probably contains the highest concentrations of fat-soluble toxins.
d. Seals are more numerous than fish.
e. The carnivores can provide more food for the Eskimos than the herbivores can.
The rate at which solar energy is converted to the chemical energy of organic compounds by
autotrophs is termed:
a.
Biomass
b. Standing crop
c.
Biomagnification
d. Primary productivity
e. Secondary productivity
A typical pyramid of energy has a broad base tapering to a narrow top. The primary reason for
this pattern is that:
a.
Secondary consumers require less energy than producers.
b. At each step, energy is lost from the system as a result of keeping the organisms
alive.
c.
As materials pass through ecosystems, some of them are lost to the environment.
d. Biomagnification of toxic materials limits the secondary and tertiary consumers.
e. Secondary consumers have a more general diet than primary producers.
