What does ecosystem diversity refer to?

• The variety of ecosystems within a larger geographic area

• The number of different habitats available in a given area

• The genetic variation within a population

• The balance of population sizes of all species in an ecosystem

Species diversity is measured by:

• The number of different genes in an ecosystem

• The number of different species in an ecosystem and the balance or evenness of the population sizes of all species in the ecosystem

• The number of different habitats available in a given area

• The difference in ecosystems within a geographic area

Genetic diversity is the measure of how:

• Many different species are present in an ecosystem

• Different the genes are of individuals within a population

• Many different habitats are available in an area

• Balanced the ecosystem is in terms of species population sizes

What is the relationship between biodiversity and ecosystem/population health ?

• Lower biodiversity leads to higher ecosystem/population health

• There is no relationship between biodiversity and ecosystem/population health

• Higher biodiversity leads to higher ecosystem/population health

• Biodiversity only affects the health of individual species, not the ecosystem

What does species richness (r) refer to in an ecosystem?

• The balance of individual organisms between different species

• The total number of individual organisms in an ecosystem

• The total number of different species found in an ecosystem

• The number of dominant species in an ecosystem

What does evenness measure in an ecosystem?

• The health of the ecosystem based on water and soil quality

• The total number of different species in an ecosystem

• How balanced the individual organisms in an ecosystem are between the different species

• The percentage of water resources in an ecosystem

What does high species richness (r) generally indicate about an ecosystem's health?

• It indicates poor ecosystem health due to overpopulation

• It suggests that there is a lack of resources like water and soil

• It is generally a good sign of ecosystem health, meaning more quality resources are available

• It means that there are too many dominant species

What does evenness indicate when it comes to species in an ecosystem?

• The number of water resources in an ecosystem

• Whether there are one or two dominant species or if population sizes are well balanced

• The total number of organisms in the ecosystem

• The health of the ecosystem based on the number of species

According to the image, what is the difference between Community 1 and Community 2?

• Community 1 has more species richness than Community 2

• Community 1 and Community 2 have different species richness

• Community 1 and Community 2 have the same species richness but different species evenness

• Community 1 has a better ecosystem health than Community 2

What is genetic diversity a measure of?

• The number of species in an ecosystem

• How different the genomes are of the individuals within a population of a given species

• The number of individuals in a population

• The size of a given population's habitat
