How does the environment affect where and how an organism lives?”

Explanation:

An organism may need to adapt to a habitat in order to live there. For example a bird’s beak may evolve over time to a skinnier size if it’s only food source is bugs in the ground. The food source is important to the organism. The predators are also important to consider. There must also be appropriate shelter for the organism. The weather is also important.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
