Almost all food chains begin with a green plant. Well, green plants convert the Sun's rays into energy through a process called photosynthesis. So what happens to the Sun's energy when it reaches Earth? Is that possible? Can you guess where that could be? Pizza doesn't come from Mars it originally comes from Italy, but if we look at something called a food chain we can see that all the energy animals get from their food originally comes from around 93 million miles away.
