Interpreting Graph Population Ecology

Front

Which of the 2 curves exhibits exponential growth? Yellow J shaped curve, Green S shaped curve

Back

Yellow J shaped curve

Front

Which of the 2 curves show carrying capacity? Yellow J shaped curve, Green S shaped curve

Back

Green S shaped curve

Front

What is the carrying capacity?

Back

1000

Front

In what generation does the population reach its carrying capacity? Options: between 14 and 16, between 16 and 18, between 20 and 22, between 24 and 26

Back

between 24 and 26

Front

For what organism is the carrying capacity shown? Options: Deer, wolf, moose, Resources

Back

Deer

Front

Why did the population decrease in 1990 after reaching its carrying capacity?

Back

Drought, temperature, predators (all of the above)

Front

Hypothesis for population exceeding carrying capacity in 1992:

• If there were more predators, then the deer population would change.
• If there was less rainfall, then the deer population would change.
• If there were more food, then the deer population would change.
• If there were a fire, then the deer population would change.

Back

If there were more food, then the deer population would change.

Front

Why did the population decrease in 1994 after it exceeded the carrying capacity?

Back

If there was a colder winter, then the deer population would change.

Front

Which of the 2 types of bacteria will soon die?

• P. aurelia
• P. caudatum
• Both P. aurelia and P. caudatum

Back

P. caudatum

Front

Which of the 2 bacteria strains is better adapted for competition?

Back

P. aurelia
