Detailed explanation-1: -All green plants can make their own food in the presence of sunlight through the process of photosynthesis. So, they have an autotrophic mode of nutrition and are also called autotrophs.
Detailed explanation-2: -Green plants are called autotrophs since they are able to synthesize their own food. In photosynthesis, solar energy is captured by the pigment, Chlorophyll. During photosynthesis, plants consume carbon dioxide and release oxygen gas. The green plants have chlorophyll in their leaves.
Detailed explanation-3: -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.
