1. the movements of energy and nutrients through living systems are different because (1 point)

energy is limited in the biosphere, and nutrients are always available.
nutrients flow in one direction, and energy recycles.
energy forms chemical compounds, and nutrients are lost as heat.

2. which of the following depends on bacteria? (1 point)
conversion of dead organic matter to fossil fuel
photosynthesis
dissolution of phosphates from rock
nitrogen fixation

1. The movement of energy and nutrients through living systems are different. 
This is because energy flows in one direction and nutrients recycle. Nutrients recycle is the exchange and movement of inorganic and organic matter back to the production of matter.
 Energy flows in one direction because it is a non-cyclic and unidirectional pathway. Mineral nutrients which are cyclic include sulfur cycle, nitrogen cycle, water cycle, and the carbon cycle.

 2. Conversion of dead organic matter to be fossil fuel depends on bacteria. Living organisms are being composed of organic compounds they excrete and secrete organic materials to their environment.
 Large molecules of organic matter can be formed from different polymerization of different parts which are already broken down to matter.
