Biodiversity Summative Assessment Review

Which of the following is true about selective breeding?

• a process to create an organism with desired traits from parents with those desired traits

• natural method of producing offspring with desired traits

• creating a new species

• increases biodiversity

• decreases biodiversity

what is the leading cause of deforestation?

• Housing market
• Agriculture and Farming
• Paper mill

How will the biodiversity of the land be affected when farmers clear forests and plant crops?

• The biodiversity will decrease with higher populations of fewer species.

• The biodiversity will increase with lower populations of more species.

• The biodiversity will decrease with lower populations of more species.

• The biodiversity will increase with higher populations of fewer species.

What is causing the pH to drop in the oceans?

• Squid ink

• Rising CO2 levels in the atmosphere

• Kelp dying

• Acid is being dumped into the ocean

What is causing an increase in CO2 in the atmosphere?

• Ocean acidification

• Dying kelp population

• Human activity (burning fossil fuels, fires, etc.)

• Hunting animals

What will happen if there is a continued decrease in the pH of oceans?

• increase in marine biodiversity and animal populations

• increase in marine biodiversity and a decrease in animal populations

• decrease in both marine biodiversity and animal populations

• decrease in marine biodiversity and an increase in animal populations

Which human activity would be most destructive to the biodiversity of the biosphere?

• a. The burning of wood and coal in rural areas
• b. The release of species of freshwater trout in lakes
• c. The removal of plants from the food webs they support
• d. The removal of erosion barriers from forest boundaries

What affect will continued rise in global temperature most likely have on worldwide biodiversity?

• a. It will have no effect as there is plenty of time for organisms to adapt
• b. It will increase due to warmer temperatures
• c. It will increase due to greater plant production from more CO2
• d. It will decrease due to massive habitat destruction

In what way are humans most impacting the biodiversity of ecosystems around the world?

• a. We are putting too many organisms in zoos or keeping them as pets
• b. We are increasing biodiversity by breeding new species
• c. We are destroying the habitats of a large number of species
• d. Recreational hunting

 Which biome is more likely to survive a change in the environment?

• High (rich) biodiversity
• Low (poor) biodiversity
