Over time the number of Amazon River dolphin deaths have decreased. Which description best describes what will happen first as a result of the decreased death rate?
The population will decrease because all of the dolphins will starve.
The population will stay the same size because the dolphins will live longer.
The population will increase because more dolphins will survive and reproduce.
The population will decrease for a while and the increase so that the population size is balanced.
What is most likely to happen second as a result of a decreased death rate?
The population will continue to increase because dolphins are living longer.
The population will begin to increase because it will be easier to find a mate.
the population will continue to change at random so that the population size is balanced.
The population will begin to decrease because there will not be enough food for all the dolphins.
