Detailed explanation-1: -Plants and algae (plant-like organisms that live in water) are able to make their own food using energy from the sun. These organisms are called producers because they produce their own food. Some animals eat these producers.
Detailed explanation-2: -They get their energy from sources other than the sun, but they are still called producers. This process is known as chemosynthesis, and is common in ecosystems without sunlight, such as certain marine ecosystems. Producers include (a) plants, (b) algae, and (c) diatoms.
Detailed explanation-3: -The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
Detailed explanation-4: -The sun is not a producer in the food chain. Nor is it a consumer nor a decomposer. All food chains though do begin with the sun.
