Students were asked for the primary source of energy for most living organisms.
Student 1 "Humans because they are top -level consumers
Student 2 "Green plants because they are the only organisms that use photosynthesis
Student 3 "Wind because it helps distribute seeds over long distances"
Student 4 " the sun because sunlight powers almost all food chains on Earth
D. Student 4
