Which phrase best describes biodiversity?

• The number of individuals in a population

• The amount of biomass in a community

• The amount of available energy in a food web

• The number of organisms in an ecosystem

What do all the biotic and abiotic factors in a given area make up?

• Habitat

• Community

• Ecosystem

• Population

Select the biome, that is best described by the statement shown:

A low amount of solar energy causes the subsoil to be permanently frozen (permafrost).

The graph here shows the population growth curves of Paramecium aurelia and Paramecium caudatum cultures after they were mixed together. One influence that could correctly be drawn from the graph is that Paramecium aurelia and paramecium caudatum cannot successfully

• Utilize oxygen for anaerobic respiration

• Utilize the same wavelengths of light

• Live in marine environments

• Occupy the same niche

The graph here show the population growth curves in Paramecium aurealia and Paramecium caudatum cultures after they were mixed together. This graph can be used to illustrate the principle of

• Mutualism

• Competition

• Assimilation

• Saprophytism

Which is an example of a biotic factor that would limit the size of a deer herd?

• Populations of predators

• Severe summer drought

• Lack of oxygen at high altitudes

• Heavy winter snowfalls

What type of population growth is shown in the graph?

• Logistic Growth

• Expontential Growth

• Carrying Capacity Growth

• Density Dependent Growth

In the graph below, what is the carrying capacity of the yeast population?

• 7.5 mg/cc

• 6.0 mg/cc

• 14 hours

• 20 hours
