Instructions
Read the following scenarios about gerbils interacting with their environment, and answer the questions that follow. Think critically about how these interactions impact ecological balance.
Scenario 1: Food Sources
A group of gerbils lives in a desert ecosystem. They primarily eat seeds and roots. However, due to a long drought, food sources have become scarce.
Question 1: How might the scarcity of food affect the gerbil population?
Scenario 2: Predators
Gerbils also have natural predators, such as birds of prey. During the summer, the number of these predators increases.
Question 2: What might happen to the gerbil population if the number of predators rises?
Scenario 3: Habitat Change
A construction project begins nearby, leading to habitat loss for the gerbils. The area where they nest and forage becomes a roadway.
Question 3: In what ways could habitat loss affect gerbil behavior and their survival?
Scenario 4: Competition
New animals, like rabbits, move into the area and compete with the gerbils for food and shelter.
Question 4: How does competition for resources affect the gerbils' chances of survival in their environment?
Scenario 5: Environmental Changes
Climate change is affecting the desert ecosystem, leading to higher temperatures and changes in vegetation.
Question 5: How do you think these environmental changes will impact the relationship between gerbils and their ecosystem?
Reflection:
Reflect on what you have learned about the interactions between gerbils and their environment. Why is it important to maintain ecological balance?
