Some land animals, such as bears and kingfishers, eat animals that live in the water. In turn, some animals, such as crocodiles, that dwell primarily in water will eat animals that live on land. Also, many amphibians, such as frogs, and also some insects, start their life in the water, where they can prey and be preyed upon.

The closing of a plants stomata will prevent plants from taking in (Carbon dioxide) or co2; Without co2, plants cannot make carbohydrates, and plants can only obtain this critical molecule (carbohydrates) when stomata are open. Hope this helps ya out :)
Passive transport is the movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. On the other hand, active transport <span>is the movement of molecules across a cell membrane from a region of their lower concentration to a region of their higher concentration which needs energy input. </span>
Simple Diffusion Across the Cell (Plasma) Membrane. The structure of the lipid bi-layer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
