Species richness is defined as

• the abundance of individuals within a species

• the number of niches a species occupies

• the diversity of species within a community

• the number of niches a species

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 B has a lower species richness.

• Community A has the same biodiversity as community B.

• Both communities have the same species evenness.

• Community A has a higher species evenness.

The three types of biodiversity are

• genetic, species and ecosystem
• medical, agricultural, ethical
• habitat loss, pollution, overharvesting
• camera traps, invasive species, cookies

The BEST definition of evolution is

• Change in genetic composition of a population over time

• Mutations in individuals

• Changes in chromosomes

• Individuals adapting to an environment

• All of these

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
