Predator Prey Relationships

What typically happens to predator populations when prey populations decrease?

• Predator populations increase

• Predator populations fluctuate randomly

• Predator populations decrease

• Predator populations remain stable

What principle explains the elimination of one species due to competition for the same resource?

• Competitive exclusion principle

• Mutual benefit principle

• Resource partitioning principle

• Symbiotic relationship principle

What is a direct consequence of the competitive exclusion principle?

• Increased biodiversity

• Decreased resource availability

• Elimination of a species

• Enhanced mutualism

How do species using resource partitioning avoid competition?

• By consuming different types of food

• By utilizing different parts of the same resource

• By reducing their population size

• By migrating to different areas

Which example best illustrates resource partitioning?

• Birds sharing the same nest

• A lion hunting in the savannah

• Trees spreading roots deeper to find water

• Two species of birds feeding at different heights of the same tree

What type of competition occurs between individuals of the same species?

• Intraspecific competition

• None of the above

• Indirect competition

• Interspecific competition

Which symbiotic relationship benefits both organisms involved?

• Commensalism

• Parasitism

• Mutualism

• Competition

In which symbiotic relationship is one organism neither harmed nor benefited?

• Predation

• Mutualism

• Commensalism

• Parasitism

Which scenario is an example of intraspecific competition?

• A bee and a butterfly on the same flower

• A fox and a wolf competing for a rabbit

• Two trees of the same species competing for sunlight

• Two different species of birds competing for worms

What happens in parasitism?

• Both organisms benefit

• Both organisms are harmed

• The host is harmed, and the parasite benefits

• Neither organism is affected
