Which sequence best represents the flow of energy through an ecosystem?
Sun → green plants → herbivores → carnivores
Sun → herbivores → producers → consumers
green plants → carnivores → consumers → herbivores
consumers → carnivores → herbivores → producers
The flow of energy in an ecosystem is best described as energy moving in
one direction from the Sun to the producers and then to the consumers
one direction from a consumer to a producer and then to the Sun as heat and light
two directions between the producers that are present
two directions, back and forth, between the producers and the consumers
Which statement best describes the role of decomposers?
They convert carbon dioxide and water to glucose.
They break down organic compounds into products used by other organisms.
They release oxygen to the atmosphere.
They provide energy for the synthesis of proteins.
Autotrophs might survive when heterotrophs cannot, because autotrophs are able to
exist without respiration
become dormant
make their own food
perform cellular respiration

Commensalism
Which relationship is best described by the following: Bear eating a salmon.
