Which of the following characteristics differentiates an autotroph from a heterotroph? question options: a heterotroph must obtain its energy from an autotroph or other heterotroph. autotrophs only obtain their energy from the sun. an autotroph can only obtain its energy from a heterotroph. an autotroph must obtain its energy from a heterotroph or other autotroph.. heterotrophs only obtain their energy from the sun. a heterotroph can only obtain its energy from an autotroph.

The option A is correct option.

A heterotroph must obtain its energy from an autotroph or other heterotroph. Autotrophs only obtain their energy from the Sun.

fe 55.85 g/mol and h2o 18.02 g/mol.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
