The particular role (job) of an organism in its environment including types of food it eats, how it obtains its food and how it interacts with other organisms is called a what?

• niche
• habitat
• home
• ecosystem

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

I. the proportion of individuals in each species

II. the total number of species

III. the number of communities each species is in

• I only

• I and II only

• II only

• II and III only
