What is competition?

• A relationship where both species benefit

• A struggle between organisms to survive in a habitat with limited resources

• A relationship where one organism benefits and the other is harmed

• A relationship where one organism benefits and the other is unaffected

What is the difference between interspecific and intraspecific competition?

• Interspecific competition occurs within a single species, while intraspecific competition occurs between different species

• Interspecific competition occurs between different species, while intraspecific competition occurs within a single species

• Interspecific competition involves mutualism, while intraspecific competition involves parasitism

• Interspecific competition involves commensalism, while intraspecific competition involves mutualism

What is symbiosis?

• A relationship where both species are harmed

• A relationship where one species is harmed and the other is unaffected

• A close and long-term interaction between two different species

• A relationship where one species benefits and the other is harmed

What is commensalism?

• A relationship where both species benefit

• A relationship where one organism benefits and the other is harmed

• A relationship where one organism benefits and the other is unaffected

• A relationship where both species are harmed

What is parasitism?

• A relationship where both species benefit

• A relationship where one organism benefits and the other is harmed

• A relationship where one organism benefits and the other is unaffected

• A relationship where both species are harmed

Explain competitive exclusion and resource partitioning.

• Competitive exclusion is when two species coexist by sharing resources, and resource partitioning is when one species outcompetes the other

• Competitive exclusion is when one species outcompetes another, leading to the exclusion of the latter, and resource partitioning is when species coexist by dividing resources

• Competitive exclusion is when species coexist by dividing resources, and resource partitioning is when one species outcompetes the other

• Competitive exclusion and resource partitioning are the same concepts

Describe a keystone predator.

• A predator that has a large effect on the health of its environment/ecosystem

• A predator that is the most abundant in its ecosystem

• A predator that only preys on one specific species

• A predator that is at the top of the food chain

What is a population?

• A group of different species living in the same area

• A group of individuals of the same species living in the same area

• A group of ecosystems with similar climates and organisms

What is a community?

• A group of different species living in the same area

• A group of individuals of the same species living in the same area

• A group of ecosystems with similar climates and organisms
