J-Shaped curves

• show a decline after an increase
• display populations that have reached carrying capacity
• represent exponential growth
• does not depend on the numbe rof resources

Which of the following is TRUE of predator/prey relationships?

• Herbivores are limited by the number of prey in an ecosystem.
• Humans are not considered predators.
• The number of predators is determined by available prey.

Predator population lags behind prey population because:

• Increase in predators leads to decrease in prey

• Increase in predators leads to increase in prey

• Increase in predators leads to decrease in producers
