Predation and Competition Flashcard

Front

What is a predator-prey relationship?

Back

A predator-prey relationship is a biological interaction between two organisms, where one organism (the predator) hunts, kills, and consumes the other organism (the prey) for food.

Front

Give an example of a predator-prey relationship in the wild.

Back

Lions and zebras.

Front

How does predation affect the population dynamics of prey species?

Back

Predation reduces the population size of prey species.

Front

What is competitive exclusion?

Back

Competitive exclusion occurs when two species competing for the same resources cannot coexist indefinitely.

Front

Provide an example of predator-prey coevolution.

Back

Cheetahs and gazelles.

Front

What is the role of predators in an ecosystem?

Back

Predators help control the population of prey species, maintaining balance in the ecosystem.

Front

What is the difference between predation and competition?

Back

Predation involves one organism hunting and consuming another, while competition involves two organisms vying for the same resources.

Front

How can predation lead to evolutionary changes in prey species?

Back

Prey species may develop adaptations such as camouflage or speed to evade predators.

Front

What is an example of a keystone predator?

Back

Sea otters are considered a keystone predator because they help maintain the balance of kelp forest ecosystems.

Front

What is the significance of the predator-prey cycle?

Back

The predator-prey cycle illustrates the dynamic relationship between predator and prey populations, showing how they influence each other's numbers.
