Detailed explanation-1: -Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy.

Detailed explanation-2: -Another major difference between autotrophs and heterotrophs is that autotrophs have an important pigment called chlorophyll, which enables them to capture the energy of sunlight during photosynthesis, whereas heterotrophs do not. Without this pigment, photosynthesis could not occur.

Detailed explanation-3: -Only certain organisms, called autotrophs, can perform photosynthesis; they require the presence of chlorophyll, a specialized pigment that can absorb light and convert light energy into chemical energy.

Detailed explanation-4: -In all autotrophic eukaryotes, photosynthesis takes place inside an organelle called a chloroplast. For plants, chloroplast-containing cells exist in the mesophyll. Chloroplasts have a double membrane envelope composed of an outer membrane and an inner membrane.

Detailed explanation-5: -On the cellular level, the reactions for photosynthesis occur in organelles called chloroplasts (in eukaryotic cells).
