The ecological footprint is a general assessement of the population while the ecological footprint per capita means the ratio a country's per capita Footprint to the per capita biological capacity available on Earth.
<h3>What is an Ecological Footprint?</h3>
This is best defined as the impact of human activities which is measured in terms of the area of biologically productive land and water required to produce the goods consumed and to assimilate the wastes generated.
The importance of Ecological Footprint is due to the fact that it does measures the biologically productive area that are needed to provide for everything that people demand from nature such as fruits, vegetables, meat, fish, wood, cotton, fibres, as well as absorption of carbon dioxide from fossil fuel burning and space for buildings and road.
In essence, the ecological Footprint assess how fast or quick the people consume resources and generate waste compared to how fast nature can absorb our waste and generate resources.

Answer:
Visible Light Absorption
Atoms and molecules contain electrons. It is often useful to think of these electrons as being attached to the atoms by springs. The electrons and their attached springs have a tendency to vibrate at specific frequencies. Similar to a tuning fork or even a musical instrument, the electrons of atoms have a natural frequency at which they tend to vibrate. When a light wave with that same natural frequency impinges upon an atom, then the electrons of that atom will be set into vibrational motion. (This is merely another example of the resonance principle introduced in Unit 11 of The Physics Classroom Tutorial.) If a light wave of a given frequency strikes a material with electrons having the same vibrational frequencies, then those electrons will absorb the energy of the light wave and transform it into vibrational motion. During its vibration, the electrons interact with neighboring atoms in such a manner as to convert its vibrational energy into thermal energy. Subsequently, the light wave with that given frequency is absorbed by the object, never again to be released in the form of light. So the selective absorption of light by a particular material occurs because the selected frequency of the light wave matches the frequency at which electrons in the atoms of that material vibrate. Since different atoms and molecules have different natural frequencies of vibration, they will selectively absorb different frequencies of visible light.
