Match each situation to the correct graph.

1. clownfish lay hundreds of eggs, but only 10% to 15% survive into adulthood.

2. 80% of elephant calves survive into adulthood.

3. A population of beetles in a newly colonized field grows exponentially.

4. A wolf population grows over a certain period and then stabilizes.

1. The bottom graph matches this statement, because it shows a drastic decrease in population.

2. The top graph matches this statement, because it shows most of the population surviving for quite some time.

3. The second graph matches this statement, because it shows a drastic increase in population.

4. This would be the third graph, because it shows a dramatic increase then a stabilization.

first graph: 80% of elephant

second graph: A population of  beetles

third graph: A wolf population

fourth graph: Clown fish lay hundreds of eggs
