Would You Help Me Write A Song?


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 :”>

Biomes/ecosystems Question? Grade 10?


For a science poster I have to arrange some terms from “biggest” to “smallest” based on how where the terms fit in a biosphere. My teacher assigned this project before we have actually started the unit, so we haven’t learned this yet and I don’t know if I have them in the right order. These are the words in the order I put them in:
Biosphere
Biome
Ecosystem
Community
Population
Habitat
Niche
Organism
Is this how you would have ordered them? I know for sure that the first and last terms are right, but I’m not sure about the rest.
