Affiliate Marketing Secrets

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.

describe four factors that affect population size
identify factors that limit population growth
explain the difference between primary and secondary succession
differentiate between habitat and niche

Dont Understand. Please Help.

the choices are:
a.different species can share the same niche in the same habitat
b.no two species can share the same niche in the same habitat
c.two species in the same habitat have to share a niche to survive
d.different species can occupy niches that are very similar
which sentences are true???

Have you ever considered you own personal habitat and niche? What might be unique about either your habitat or particularly your niche the differentiates it from your classmates’ habitats and niches?

tell whether each thing involves abiotic or biotic factors
commensalism
competition
habitat
mutualism
niche
predation
