How do autotrophs and heterotrophs obtain the materials needed to build needed macromolecules (2 different sources for autotrophs?) How are organelles structurally adapted to maximize the uptake of these materials?

Hello there.

How do autotrophs and heterotrophs obtain the materials needed to build needed macromolecules (2 different sources for autotrophs?) How are organelles structurally adapted to maximize the uptake of these materials?

Organisms that can produce their own nutrients are called autotrophs, Ones that can't are called heterotrophs

Organisms that can produce their own nutrients are called autotrophs, while the organisms that cannot produce their own food are called heterotrophs. Heterotrophs obtain the materials from the food they eat while autotrophs make their own nutrients. Hope this answers the question.
