Mississippi Science BIO.5.1
The Standard
- BIO.5
- Students will Investigate and evaluate the interdependence of living organisms and their environment.
Illustrate levels of ecological hierarchy, including organism, population, community, ecosystem, biome, and biosphere.

What This Standard Means
What Students Need to Do
- Students draw or label six nested levels, from one living thing to all places on Earth where life exists. They show when other species and nonliving parts enter the picture. They distinguish a local ecosystem from a biome, a broad region with similar climate and life.
What Mastery Looks Like
- Given a forest scene, a student labels each level from one oak to the biosphere. They place soil and sunlight in the ecosystem, but not the community.
Common Misconceptions
- Students may call several different species a population or count rocks and sunlight as members of a community. They may treat one forest ecosystem as a whole biome or think the biosphere means only the atmosphere.
How to Assess It
- Give students a sketch of a forest with three oaks, a squirrel, mushrooms, soil, and sunlight. Ask them to label the organism, population, community, and ecosystem, then name the broader levels.

Ways to Teach It
Give pairs six nested paper circles to sketch one oak, nearby oaks, other species, soil and rain, temperate deciduous forest, and Earth.
Ask: Why does adding soil and sunlight to an oak, squirrels, and fungi change the diagram from a community to an ecosystem?
Race to match cards showing one oak, local oaks, forest life, forest life plus soil, temperate deciduous forest, and Earth to level names.
Find your town on a biome map, name its biome, and explain how a nearby park ecosystem fits within it.
