Question: What is intraspecific competition?
Answer: Competition for food and other requirements between organisms of the same species.
Card 3
Question: How many species are involved in interspecific competition?
Answer: Two or more species.
Card 4
Question: How many species are involved in intraspecific competition?
Answer: One species (members of the same species).
Card 5
Question: What is the main reason for interspecific competition according to the content?
Answer: Lack of physical resources such as food and habitat.
Card 6
Question: What is the main reason for intraspecific competition according to the content?
Answer: Overpopulation or an increase in species density.
Card 7
Question: Is competition for mating observed in interspecific competition?
Answer: Not observed.
Card 8
Question: Is competition for mating observed in intraspecific competition?
Answer: Widely observed.
Card 9
Question: What are the two possible outcomes when competition intensifies within the same ecological niche?
Answer: Competitive exclusion or competitive co-existence.
