The flow of energy in an ecosystem is best
described as energy moving in
(1) one direction from the Sun to the producers
and then to the consumers
(2) one direction from a consumer to a
producer and then to the Sun as heat and
light
(3) two directions between the producers that
are present
(4) two directions, back and forth, between the
producers and the consumers
1, as the energy comes from the sun, then plants get it through photosynthesis, and finally the consumers obtain the energy from consuming animals on a lower trophic level than themselves. energy cannot flow down the food chain, only up.
