The plants use the sun as their energy, using photosynthesis.
The insect and animals get their energy from the food they eat.
And bacteria get their energy by decomposing dead organisms.
You might have to do the research on what each animal eats if you need specific answers.
I'm sorry this isn't much, but hope this helps you out! :)
Because it uncovers a truth many don’t see in science theory’s and thing that people might not have know giving them the curiosity to try something new and learn something new.
Cellular differentiation describes how different cells perform different processes and have unique functions. There are at least 250 cells in the human body and each one plays a different role, and <em>all</em> of them are crucial to the body's ability to maintain homeostasis. For example, liver cells produce proteins that are important in blood clotting. If these cells are damaged, blood will not clot properly. If blood does not clot, a body cannot maintain homeostasis and the person will fall ill.
TL;DR: every cell plays its part and keeps the organism alive.
