How do heterotrophs obtain energy?
A
By directly absorbing energy from inorganic sources
B
By synthesizing glucose from carbon dioxide and water
C
By consuming organic molecules produced by other organisms
D
By converting sunlight into chemical energy through photosynthesis
Verified step by step guidance1
Understand the definition of heterotrophs: Heterotrophs are organisms that cannot produce their own food and must obtain energy by consuming other organisms or organic matter.
Recognize the difference between heterotrophs and autotrophs: Autotrophs, such as plants, can produce their own food through processes like photosynthesis, where they convert sunlight into chemical energy.
Identify the source of energy for heterotrophs: Heterotrophs rely on organic molecules, such as carbohydrates, proteins, and fats, which are produced by other organisms, to obtain energy.
Consider examples of heterotrophs: Animals, fungi, and many bacteria are heterotrophs because they consume organic matter for energy.
Conclude that heterotrophs obtain energy by consuming organic molecules produced by other organisms, rather than directly absorbing energy from inorganic sources or synthesizing glucose from carbon dioxide and water.
