I need to write a song about ecology and ecosystem in the tune of Bruno Mars’ Count on Me.
It should also consist terms like Manmade and Natural resources, Biotic and Abiotic, Community, Population, Habitat, Ecological niche, Food Chain, Food Web, Interrelationships and Energy Pyramid.
Anyone who could give me any lyrical ideas or construct a sample lyrics would be rewarded 5 stars.
Thank You again :”>
