Jelly Population Explosions Quiz

What is a population explosion in an ecosystem?

• A sudden increase in the number of different species in an ecosystem

• A rapid increase in the population of a specific species in an ecosystem

• A stable population of organisms in an ecosystem

• A decrease in the number of living organisms in an ecosystem

Why are people concerned about jelly population explosions?

• Because it leads to an increase in fish population

• Because it has no impact on the environment

• Because it causes a decrease in zooplankton population

• Because it affects human activities and ecosystems
