Verified step by step guidance

Understand the definitions: Autotrophs are organisms that can produce their own food from inorganic substances, typically through photosynthesis or chemosynthesis. Heterotrophs, on the other hand, obtain their energy by consuming other organisms or organic matter.

Identify the key difference: The primary distinction between autotrophs and heterotrophs is how they obtain energy. Autotrophs convert inorganic substances into organic matter using light or chemical energy, while heterotrophs rely on consuming organic substances.

Analyze the options: Consider each option provided in the problem. 'Their method of obtaining energy' directly relates to the fundamental difference between autotrophs and heterotrophs.

Evaluate the relevance of other options: 'The characteristics of life' and 'Their mode of inheritance' are general biological concepts that do not specifically address the energy acquisition methods of these groups. 'The way that they generate ATP' is related but not the primary distinction.

Conclude with the correct choice: Based on the analysis, the correct answer is 'Their method of obtaining energy,' as it directly addresses the fundamental difference between autotrophs and heterotrophs.
