The Standard
Describe and investigate various limiting factors in the local ecosystem and their impact on native populations, including food, shelter, water, space, disease, parasitism, predation, and nesting sites.

What This Standard Means
What Students Need to Do
- Students identify limiting factors in a local ecosystem and explain how each can change a native population. They use observations or data to investigate effects over time.
What Mastery Looks Like
- A student can examine a graph, field count, or scenario and name the factor limiting population growth. They can support a cause-and-effect claim with evidence and predict what may happen next.
Common Misconceptions
- Students often treat every population decline as a food shortage and confuse a predator with a parasite. They may overlook shelter, space, disease, water, and nesting sites when explaining population changes.
How to Assess It
- Exit ticket: Beach development removes shorebird nesting areas, but food and water remain stable. Name the limiting factor and predict the population effect.

Ways to Teach It
Survey four schoolyard quadrats, tally food, water, shelter, and nesting sites, then predict which native animal each area could support.
Write a claim explaining which factor would most limit rabbits in a crowded field with plentiful grass but few hiding places.
Use animal tokens, resource cards, and event cards to model population changes caused by drought, disease, predation, and habitat loss.
Compare a local development map with native species habitat data, then identify which resources or spaces may become limited.
