Ecosystem Balance
Grade 5 · Science · Ecosystems · Nova Scotia, Canada
Lesson Summary
Understand how populations of plants and animals depend on each other to keep an ecosystem balanced.
Explanation
In a healthy ecosystem, populations of producers, consumers, and decomposers stay in balance. If the number of one species changes a lot, it affects others. For example, if too many deer eat the plants, the plants decrease, and then the deer run out of food. Predators help keep balance by controlling prey populations. Natural events like fires and droughts can also shift the balance, but ecosystems often recover over time.
Practice Questions
Q1: What might happen if a predator is removed from an ecosystem?
Answer: The prey population could grow too large, eat too many plants, and damage the ecosystem.
Q2: How do predators help keep an ecosystem balanced?
Answer: They control the size of prey populations so that prey do not eat all the producers.
Q3: What does 'ecosystem balance' mean?
Answer: It means the populations of different species in an ecosystem are at levels where they can all survive without one group overwhelming the others.
