Answer:
Top to bottom: 5, 3, 2, 4, 1
Explanation:
I'll take a shot! Here I go!
5 (Sun) = top; we get all our energy from the sun
Then 3 (plants); plants can convert sunlight into food for themselves via photosynthesis
Then 2; we're talking about herbivores that eat plants, right?
Then 4; these are probably~ carnivores
Then 1; when a living thing dies, these guys consume the corpse and return the energy to the ecosystem
Have a great day!
