In facilitated diffusion.molecules only move with the aid of a protiein in the membrain simple diffusion is passive but facliitaed diffusion is an active process that uses energy simple diffusion requires molecules to move through special doorways in the cell membrane
Given what we know, we can confirm that the "balance of nature" refers to a scientific theory about ecological homeostasis.
<h3>What does ecological homeostasis mean?</h3>
- This refers to the idea of a perfect balance in an ecosystem.
- It is the theory that all aspects of an ecosystem are and will remain balanced even if there are small changes.
- This implies that any minor change in an ecosystem will be corrected.
- This will happen through natural regulation mechanisms such as positive or negative feedback.
Therefore, we can confirm that the "balance of nature" is the scientific theory that all things in an ecosystem will remain balanced, meaning that if there is a small change, it will be corrected through some form of natural regulatory mechanism.
