and function of the
ecosystem
2A: Identify and describe the following components of species
interactions
Biological populations
Biological communities
Species interactions (mutualism, commensalism, predation, paratism)
Major terrestrial and aquatic biomes
Keystone species

Sort
Step 1: Record the definitions into your Species Interaction table
Step 2: Read through the species interactions and sort them into
the appropriate column
Step 3: Determine which graphs match each of the interactions
based on the energy gained/lost
