Unit 4: My Community Ecology

Ecology & Biodiversity

Day 1- Species Interaction

Scale

Level 3 Level 23A: Based on our

development site, predict

the impact of removing a

species on the structure

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

Food webs

Trophic levels

Ecological pyramids (energy, biomass, population)

Law of Thermodynamics

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
