NGSS HS-LS4-4: Explore how natural selection, artificial selection (selective breeding), and CRISPR genetic modification affect crop yield and pest resistance.
Simulation Controls
Plants survive based on resistance to pests. Yield is not actively selected.
No PestsSwarm
CRISPR Gene Target
Key Concepts
Yield (Size): How much crop is produced. Takes energy.
Resistance (Color): Ability to survive pests (darker green = higher resistance).
Trade-off: Naturally, high resistance costs energy, reducing maximum yield.
