Which is the best example of a population bottleneck?

• A tsunami wipes out the entire population of plants

• A new food source is available to a population of cats

• A wild fire kills off a significant portion of a deer population

• Climate change causes the local population of birds to migrate elsewhere

Two savanna communities both contain 15 plant species. In community A, each of the 15 species is represented by 20 individuals. In community B, 10 of the species are each represented by 12 individuals; the remaining 5 species are each represented by 3 individuals. Which statement best describes the two communities?

• Community A has the same biodiversity as community B
• Both communities have the same species evenness
• Community B has a higher species richness
• Community A has higher species evenness

What is a difference between primary and secondary succcession?

• Primary succession already has soil

• Lichen and moss are seen in secondary succession
