In a given ecosystem/community which of the following is NOT part of the usual path that nutrients follow?
a. usually plants absorb nutrients from the soil
b. ultimately decomposers return the nutrients from dead organisms back to the soil
c. the nutrients pass from one trophic level to a higher trophic level as consumers eat lower-trophic-level organisms
d. nutrients are continuously added to the soil from degrading bedrock and thereby replace nutrients in the ecosystem as the nutrients dissipate out of the ecosystem because nutrients are not recycled within the ecosystem
