Explain structural and behavioral adaptations, analyze animal-plant mutualism in pollination, and compare seed dispersal mechanisms.
Construct and interpret simple food chains and trophic relationships identifying producers, consumers, and decomposers, describe interdependent relationships between living things and their physical environments (including pollination and seed dispersal by wind, water, and animals), and explain structural and behavioral adaptations for survival.
Ask scientific questions and define engineering problems based on observations of natural phenomena, texts, and investigations, formulate testable predictions and conjectures, and plan and conduct fair descriptive investigations following safe laboratory and field procedures.
