What type of organism can make its own food using sunlight?

The correct answer is autotroph because autotrophs are organisms that can produce their own food using sunlight through a process known as photosynthesis. During photosynthesis, autotrophs, such as plants, convert light energy from the sun into chemical energy in the form of glucose, which serves as food for the plant. This ability to create their own energy source makes autotrophs a fundamental part of the ecosystem, as they form the base of food chains and provide energy for other organisms that cannot make their own food.

On the other hand, heterotrophs cannot synthesize their own food and must consume other organisms for energy, while decomposers break down dead organic material, recycling nutrients back into the environment. Consumers are organisms that rely on other organisms as their food source and do not have the capability to produce their own energy through photosynthesis.
