24.2 Competition

What does interspecific competition refer to?

• Competition for mating rights only

• Competition within the same species

• Competition within the same family

• Competition between different species

What principle is exhibited in interspecific competition?

• Resource distribution principle

• Natural selection

• Competition exclusion principle

• Survival of the fittest

What happens to the less well adapted species in interspecific competition?

• It thrives and multiplies

• It becomes the dominant species

• It remains unaffected

• Its population size decreases, possibly leading to extinction

What does intraspecific competition involve?

• Competition between different ecosystems

• Competition for sunlight only

• Competition between predators and prey

• Competition within the same species

How does the population size change in intraspecific competition?

• It remains constant

• It decreases indefinitely

• It increases indefinitely

• It decreases then increases in a cyclic pattern

What is a key factor in determining the outcome of competition?

• The color of the organisms

• The speed of the organisms

• The size of the organisms

• Adaptation to the environment

What prefix is used to denote competition within the same species?

• Inter-

• Intra-

• Sub-

• Extra-

What can cause a decrease in population size in intraspecific competition?

• A decrease in the number of predators

• An increase in the number of species

• An increase in available resources

• A decrease in available resources

What is the result of competition exclusion principle?

• Increase in biodiversity

• Decrease or extinction of the less adapted species

• Temporary migration of species

• Equal resource distribution

What does the fluctuation in population size indicate in intraspecific competition?

• Stable ecosystem

• Constant resource availability

• No competition exists

• Cyclic changes in resource availability
