Question

1. Before the introduction of the yellow crazy ant to Christmas Island, land crabs ate many plant seedlings in the forest, maintaining a relatively clear forest floor. As the crab population has declined, plant seedlings have flourished. The forest floor is now covered with plants. Which statement best describes what is occurring on the forest floor? (Points : 1)
Primary succession is occurring because the ant is a new species changing the ecosystem.
Secondary succession is occurring because the organisms on the forest floor are changing.

Answer 1

Primary succession is occurring because the ant is a new species changing the ecosystem.
Secondary succession is occurring because the organisms on the forest floor are changing.
Climax vegetation is occurring because the seedlings finally have the chance to grow.
Primary succession is occurring because more plant life is healthier for the ecosystem.

Yellow crazy ants live in large colonies, scouring the forest floor for food and space. Which situation is most likely occurring in this ecosystem? (Points : 1)
The ants are not likely to change the structure of the ecosystem.
Native land crab species will quickly develop defenses against the ants.
Many forest floor-dwelling organisms will be displaced by the ants.
The ants will eventually destroy the entire ecosystem.
