Which of the following best describes a heterotroph?
A
An organism that reproduces asexually
B
An organism that can survive without oxygen
C
An organism that obtains energy by consuming other organisms
D
An organism that produces its own food through photosynthesis
Verified step by step guidance1
Understand the term 'heterotroph': In biology, a heterotroph is an organism that cannot produce its own food and instead obtains its energy and nutrients by consuming other organisms.
Differentiate between autotrophs and heterotrophs: Autotrophs are organisms that can produce their own food, typically through photosynthesis or chemosynthesis, whereas heterotrophs rely on other organisms for sustenance.
Analyze the options given: The first option describes a mode of reproduction, not energy acquisition. The second option describes an organism's ability to survive without oxygen, which is unrelated to how it obtains energy.
Identify the correct description: The third option, 'An organism that obtains energy by consuming other organisms,' accurately describes a heterotroph.
Consider the last option: 'An organism that produces its own food through photosynthesis' describes an autotroph, not a heterotroph.
