Question

explai the flow of energy between various components of environment.

Answer 1

At the first trophic level, primary producers (plants, algae, and some bacteria) use solar energy to produce organic plant material through photosynthesis. ... Decomposers process large amounts of organic material and return nutrients to theecosystem in inorganic form, which are then taken up again by primary producers

Answer 2

#Flow of energy is unidirectional.

#Terrestrial plants take about 1% of the Sun’s energy and change it to

chemical energy.

# A great deal of energy is -lost as heat/ used for digestion/doing

work/growth and reproduction.

# Only 10% of organic matter present at each trophic level (and available to

next trophic level).

#Food chains are mainly of 3-4 trophic levels (because of 10% law) .

#The number of producers are maximum (the number reduces in subsequent

trophic levels).

#Food webs are more common (as compared to isolated food chains).

#Biological magnification can be observed.
