1.	Give scientific reasons : (a) The pyramid of energy is always upright . (b) In an ecosystem the energy flow is always unidirectional . (c) Ozone present in the startosphere is called as " good ozone " .
Answer» (a) The pyramid of energy is always upright . Pyramid of energy is always upright , because energy flows from a paricular trophic level to next. Some energy is lost in the process thus it can never be inverted . (b) In an ecosystem the energy flow is always unidirectional . An energy captured by autotrophs does not go back to solar energy , i.e., which passes to herbivores does not go back to autotrophs . (c) Ozone present in the stratosphere is called as "good ozone ". As ozone absorbs UV rays from sun , which is harmful to living organism .
