Ecosystem Dynamics and Population Effects

Mr. Van de Graaff introduces lesson 3.2 on competition in ecosystems, focusing on how population sizes change due to resource competition. The lesson includes a warm-up activity, an article review on jelly populations, and a detailed simulation walkthrough. Students are guided through using a simulation tool to understand indirect effects in ecosystems. The lesson concludes with homework instructions and a reminder about COVID-19 precautions.

What is the main focus of the lesson on competition in ecosystems?

• The role of predators in maintaining balance

• The migration patterns of sea turtles

• The impact of climate change on ecosystems

• The effect of resource competition on population sizes

How does an increase in the hyena population affect the lion population?

• The lion population increases

• The lion population remains stable

• The lion population decreases

• The lion population migrates

What indirect effect do sardines have on the jelly population in northern Bangla?

• They increase the jelly population

• They have no effect on the jelly population

• They cause the jelly population to migrate

• They decrease the jelly population

What is the first step in accessing the simulation tool?
