In this food chain energy moves from one living thing to another. what source of energy starts this food chain?

It is usually a plant or something that can make its own food

plants make their own food by photosynthesis plants such as grass are eaten my other animals (e.g. cows)

However, the energy that gives the light photosynthesis is the sun.
all things that start a food chain are called producers

That is true tge cactus as a structural adaptation to its envirinment has it leaves reduced to spines. but this doesnt mean it cant produce food it produces food because of the presence of chlorophyll in its stem
