Answer 1

The movement of matter and energy from an autotroph to a heterotroph occurs when a primary producer (autotroph) is consumed by a primary consumer (heterotroph). In this case, the autotrophs are plants and the heterotrophs are animals that eat those plants or other animals.

From the options provided, the following statements represent the movement of matter and energy from an autotroph to a heterotroph:

C: The tree leaves are eaten by the giraffe. (Tree leaves are from an autotroph - the tree, and the giraffe is a heterotroph consuming it.)

E: The grass is eaten by the grasshopper. (Grass is from an autotroph - the grass, and the grasshopper is a heterotroph consuming it.)

So, the correct responses are C and E.
