A small, cold creek flows through a dense forest. The trees that line the banks of the
creek provide shade for most of the day. Algae grow well only in the few areas of the
creek that receive direct sunlight for several hours each day. Most of the food energy
enters the creek ecosystem in the form of dead leaves that fall from the trees.
According to the food web, which of these best describes the role of the dead organic
matter?
A carnivore
B herbivore
C omnivore
D producer
According to the food web, which of these is a predator?
A Brown Stonefly B Black Stonefly C Caddis Fly D Mayfly
A fire swept through the forest, burning all the leaves but leaving the trees standing.
This greatly increased the amount of direct sunlight reaching the creek, but did not
produce more than the usual amount of erosion. As a result of the fire, which of these
most likely increased in the creek?
A organic matter
B Brown Stoneflies C Caddis Flies
D Algae
