The photograph shows a snowy egret, which is adapted to live in wet places. Describe three adaptations that help the egret to live in its habitat. For each adaptation, explain how it helps the egret to survive

I’m not exactly sure what your trying to ask, but if it’s how an organelle is similar to a body system or a part a nucleus is like a in function. but i don’t fully understand what you’re trying to ask

What's the question?

Although i don't know what is the simulated system, starfish are predators that eat mostly  microalgae,  snails, sponges, bivalves, mussels and other small marine animals. removing starfish from any system would definitely increase this animals that they prey.
