Effect of sulfur dioxide

• Deprives body of oxygen
• Irritates the eyes
• Causes global warming
• Causes acid rain

When toxins build up in living things as they go up the food chain

• biomagnification
• global warming
• eutrophication
• umbrella species

What animals are most affected by ocean acidification?

• Clams, Snails, Corals, and other animals that rely on Calcium Carbonate for their skeletons
• Large fish and mammals due to the low pH of the water
• Planktonic drifters, such as jellies and salps
• Humans, because we can no longer drink ocean water due to its acidity

Which type of growth is best illustrated by this rabbit population?

• exponential
• logistic
• S-shaped
• predator-prey

What are some consequences of deforestation?

• increased population in cities
• building of more infrastructure
• soil erosion, loss of biodiversity, loss of ability to remove CO2
• more mercury and cyanide released into rivers

What is Carrying Capacity?

• A type of limiting factor.
• The maximum number of individuals that a species can support.
• The type of species.
• A kind of rabbit.

Soil erosion can be best prevented by

• removing grass from the steepest slope.
• keeping trees and plants in place
• heavily watering the vegetation on the slope.
• increasing the slope of the land by adding more soil.

Which of the following historical events most likely triggered the largest increase in the human population? 

• the Black Death plague, which occurred in the mid-1300s
• the domestication of wheat crops, which began around 8000 B.C
• the fall of the Roman Empire, which occurred around A.D. 800
• the Industrial Revolution, which began in the late 1700s
