Question 1

This graph represents three different populations.Use it to answer the following questions.
  
-Which of the following choices matches this figure?

Accepted Answer

A) Dolphins produce only single offspring at a time and provide parental care for many months. 
B) During "mating frenzies," male and female squid aggregate and release hundreds of eggs and sperm into the water column.The fertilized eggs are often quickly preyed on by fish. 
C) The century plant grows for many years and reproduces and releases hundreds of seeds just once before it withers and dies.Because of the dry desert environment in which it lives,many of the seeds do not survive or are eaten. 
D) In some species of lizards and rodents,survivorship is constant over the life span.
