The right answer is Whales are able to conserve oxygen better than humans.
As the duration of the dive of some whale species can reach more than one hour, they use other means to breathe. In vertebrates, myoglobin, a protein, transports and stores oxygen in muscle tissue. It works like hemoglobin that carries oxygen in red blood cells. It is also myoglobin concentration very strong that makes their flesh bright red color, almost black. Thus, whales use the oxygen stored in the muscles to dive for long periods.

Ionic bonds refer to a
complete transfer of electrons between atoms to produce 2 oppositively ion
charged. In this kind of bond, the metal loses its electron to become a
positive charge and vice versa.
There can be a lot of elements that can be combined to produce an ionic
bond.
One example is the fluorine and the lithium.
Flourine is an element with a symbol of F and contains the lightest
halogen while lithium is an element with symbol of Li, known to become a
silver metal.
In most ecosystems, the original source of energy for the living things in the system is the sun.
