The boundary between conducting zone and respiratory zone structures occurs at the terminal bronchiole/respiratory bronchiole junction. The major respiratory structures span the nasal cavity to the diaphragm. Functionally, the respiratory system can be divided into a conducting zone and a respiratory zone. The conducting zone of the respiratory system includes the organs and structures not directly involved in gas exchange. The gas exchange occurs in the respiratory zone.

The preferred prey item would be frogs.

What is optimal foraging theory?

It is a theory in ecology that proposes that predating animals that get the most energy from minimal efforts are favored by natural selection.

In order words, selection forces prefer investing minimum energy in order to extract maximally available energy.

In this case, the heron needs to use the lowest time to harvest the maximum energy possible. Since all the preys offer the same amount of energy, the one that requires the lowest time would be preferable for the heron.

In other words, frogs would be the most preferable prey.

What are enzyme and activation energy?
Ksju [112]

Answer:

Enzymes are proteins that bind to a molecule, to modify it and lower the energy required to make it react. ( In other words , enzymes are biological catalysts.

Catalysts lower the activation energy for reactions.

In simple terms , The lower the activation energy for a reaction, the faster the rate. )

The activation energy is the energy needed to start a reaction.

Explanation:

Thus enzymes speed up reactions by lowering activation energy.
