In mother nature, sharing is caring………….or so says Quantum and Kagome!
 
But yes, nature will give to its creatures by growing beautiful shrubs, trees and grasses to feed on.  
Then a long time later the creatures will become the grass and other plants themselves and thus completes the circle of life.
 
This is actually, if you want to get into my own canon, this particular Acacia tree is special to both Obi and Nuk, because this is the exact spot where they met when they were very young. I think they saw each other at the watering hole and decided to have a good snack together at this tree, (which by the way was much smaller at the time.) If it was this tall, they wouldn’t be able to reach the leaves.
