The answer relates to the medium in which the sensed molecules travel. On land, animals detect a scent through organic molecules transported in the air. Land animals will experience a taste sensation by grasping an object using their mouth. Here, the organic molecules providing the sensation are transported by saliva or organic fluids of the object. So on land, there is a clear distinction between molecules transported in the wind and those that can be tasted. Water is a much more dense medium than air, and can carry small and large organic molecules, unlike air. Therefore, aquatic animals have little need for olfactory organs as all molecules can be 'tasted' from the water.

i dont think i can explain it easy sorry
Explanation:
The first law, also known as Law of Conservation of Energy,Thermal energy is the internal energy of an object due to the kinetic energy states that energy cannot be created or destroyed in an isolated system. | Nuclear energy originates from the splitting of uranium atoms a process called fission. This generates heat to produce steam, which is used by a turbine generator.
then the chemical bonds are broken, | the potential energy is released in the form of kinetic energy or energy of motion and heat or non useable energy. The kinetic energy is used to do work. | Objects have mechanical energy if they are in motion and or if they are at some position relative to a zero potential energyposition for example, a brick held at a vertical position above the ground or zero height position. A moving car possesses mechanical energy due to its motion
The second law of thermodynamics states that the entropy of any isolated system always increases.
