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 first one
Explanation:
The animals above it can no longer eat it, and the animals below it will no longer be eaten by it.
Answer:
an atom with eight protons and seven electrons
an atom with eight protons and eight electrons
an atom with eight protons and no electrons
Explanation:
To tell atoms of the same element, it is safe to look at the number of protons. In neutral atoms, the number of protons will be equal with that of electrons but nonetheless, electrons are easily knocked out of their orbit to create charged atoms. Neutrons, on the other hand, can slightly vary in number creating different isotopes of the element. Changing the protons would change the atom into that of another element. Protons, therefore, are used to place an element on the periodic table.
