Answer:
As per my full understanding,
There are two main modes of nutrition:
Autotrophic – Plants exhibit autotrophic nutrition and are called primary producers. Plants synthesis their food by using light, carbon dioxide and water.
Heterotrophic – Both animals and human beings are called heterotrophs, as they depend on plants for their food.
WHEREBY: TERMS IN THIS TWO SETS ARE:
Chemohetrotroph. Gets energy from chemicals and carbon from other sources.
Photohetrotroph. Gets energy from light and carbon from other sources.
Chemoautotroph. Gets energy from chemicals and produces its own carbon.
Photoautotroph. Gets energy from light and produces its own carbon.
