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.

Answer:
The implications are epidemies, risk factors and disease burden.
When it comes to Typhoid, the cronic earners are treated with prescribed antibiotics, changes in sanitary habits and blood testing.
When it comes to hepatitis b, the cronic earners are treated with prescribed antivirals, blood tests, liver ultrasound and biopsy.
Explanation:
<em>Epidemies can occur because the sick population, might not be aware and contaminate the other amount who is not infected. That is the reason why the chronic earners must take the prescribed antibiotics for as long as the physician has prescribed, they must incorporate healthy sanitary habits like washing their hands with soap after using the bathroom, not preparing or serving food to other people. Because these actions will prevent others from getting the illness. And finally, they must get tested so that the doctor can ensure that no Salmonella Typhi bacteria remain in their body. The best way to avoid Typhoid is by vaccine.</em>
<em>Hepatitis B epidemies, risk factors and disease burden happens when the chronic earner use illegal injected drugs and share the niddle, have unprotected sex with multiple partners, receive kidney dialysis or live with someone who has hepatitis B. So the best way of managing these patients is by lifetime treatment, which means that they will take antiviral medications, interferon injections or have a liver transplant. </em>
<em>The best way of preventing the hepatitis B is by vaccine, safe sex and no drugs.</em>
No, because it is still the same rock, and the rock would eventually erode into nothing.
