DENDROLOGY

Detailed explanation-1: -A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs.

Detailed explanation-2: -A heterotroph (/ˈhɛtərəˌtroʊf, -ˌtrɒf/; from Ancient Greek (héteros) ‘other’, and (trophḗ) ‘nutrition’) is an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter.

Detailed explanation-3: -“Heterotroph is an organism that is unable to synthesize its own food, and therefore, has to rely on other sources, specifically plant and animal matter.” All animals and non-photosynthetic plants are classified as heterotrophs since they are unable to prepare food.
