The flow of energy in an ecosystem is bestdescribed as energy moving in(1) one direction from the Sun to the producersand then t
o the consumers(2) one direction from a consumer to aproducer and then to the Sun as heat andlight(3) two directions between the producers thatare present(4) two directions, back and forth, between theproducers and the consumers
Bulk flow is an energy-requiring mechanisms, whereby water and solutes move through the cell due to its pressure gradient. This process is much faster when compared to osmosis and diffusion.
