Description

This is a fun lesson in where students will research symbiotic relationships found in nature.

Performance Expectations

MS-LS2-1   Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.

Disciplinary Core Ideas

  • Organisms, and populations of organisms, are dependent on their environmental interactions both with other living things and with nonliving factors.
  • Similarly, predatory interactions may reduce the number of organisms or eliminate whole populations of organisms. Mutually beneficial interactions, in contrast, may become so interdependent that each organism requires the other for survival. Although the species involved in these competitive, predatory, and mutually beneficial interactions vary across ecosystems, the patterns of interactions of organisms with their environments, both living and nonliving, are shared.

Crosscutting Concepts

  • Phenomena may have more than one cause, and some cause and effect relationships in systems can only be described using probability.
  • The transfer of energy can be tracked as energy flows through a natural system.
