One of the most important sources of energy is the sun. The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells
1) Renewable energy
energy from a source that is not depleted when used, such as wind or solar power
2) non renewable energy
A non-renewable resource is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption
Answer:

3. From an economic standpoint an Ecosystem service is ‘a good or service flowing from an ecosystem that is of value to humans and occurs naturally’. Ej = r (N) Ej = jth ecosystem service N = natural capital (ecosystem structure) r = ecosystem function or process Example: Water quality= r (precipitation, terrain, soils, aquifers, biota) Introduction…
