Mississippi Science ENV.1.4
The Standard
- ENV.1
- Students will investigate the interdependence of diverse living organisms and their interactions with the components of the biosphere.
Describe symbiotic relationships (e.g., mutualism, parasitism, and commensalism) and other co-evolutionary (e.g., predator-prey, cooperation, competition, and mimicry) relationships within specific environments.

What This Standard Means
What Students Need to Do
- Students describe how species affect each other in a named habitat. They identify mutualism, parasitism, commensalism, predation, competition, cooperation, and mimicry from specific examples. They explain how traits such as warning colors affect these interactions.
What Mastery Looks Like
- Given forest species pairs, students name each relationship and explain what happens to both species. They distinguish a tick feeding on a deer from an owl catching a mouse. They explain why an orchid growing on a tree and a hoverfly resembling a wasp are different relationships.
Common Misconceptions
- Students often call every pair that lives together mutualism. They may call a predator a parasite, assume commensalism benefits both species, or mistake mimicry for camouflage.
How to Assess It
- On an exit ticket, describe a forest tick feeding on a deer and an orchid growing on a tree. Ask students to name each relationship and explain the effect on both species.

Ways to Teach It
Give groups forest bee-flower, deer-tick, and owl-mouse cards with benefit, harm, and no-effect counters to model each pair.
Ask: How might birds that avoid wasps affect which hoverflies survive, and why would wasp-like stripes help?
Hand out relationship bingo cards; call clues about deer-tick, orchid-tree, owl-mouse, competing saplings, pack-hunting wolves, and hoverfly-wasp pairs.
Show an orchard pollination photo; students explain what apple trees gain from bees and what bees get from apple blossoms.
