Recently the tiger population has increased. What will likely happen to the worm population? * A: increase. The larger tiger population will lead to fewer wild pigs. The smaller wild pig population will need fewer energy storage molecules to reproduce, so they will eat fewer worms.

b: increase. An increase in the size of any population leads to an increase in the sizes of all other populations in an ecosystem.

c: stay the same. Tigers do not eat worms, so the number of births and deaths in the worm population will stay the same.

d: decrease. The larger tiger population will leave fewer energy storage molecules available in the ecosystem for the worm population.

Some species of wasps are social. the queen starts a colony from scratch each spring. she builds a small nest, and lays and raises a group of female workers. the workers enlarge the nest while the queen continues to lay eggs. unfertilized eggs become males that mate with newly hatched females. all of the wasps except the newly fertilized females die by the summer. which best describes this behavior? a)it is beneficial only to the males that do not fertilize eggs. b)it is beneficial only to the female workers that are not fertilized. c)it is beneficial to each one of the individual colony members. d)it is beneficial to the whole species, but not to all of the individual members.
