A student places 10 cockroaches and 10 stones in separate containers with mesh lids. The student adds food and water to each container. After a few days, the student observes that the number of cockroaches has increased, while the number of stones has remained the same. The student concludes that cockroaches are living organisms. Which criteria supports the conclusion that cockroaches are living?

• ability to breathe

• ability to move

• ability to grow

• ability to reproduce

• Living organisms pass identical traits on to offspring.

• Living organisms grow and develop over time.

• Living organisms are all made of one cell.

• Living organisms consume oxygen to breathe.
