Understanding Symbiotic Relationships

What tiny organisms live on our skin in a commensal way?

• Bacteria

• Microscopic mites

• Fungi

• Viruses

What is predation, and who are the predator and prey?

• Predation is a relationship where one organism, the predator, hunts and eats another, the prey.

• Predation is a symbiotic relationship where both organisms benefit from each other.

• Predation is a process where organisms compete for the same resources without direct interaction.

• Predation is a form of mutualism where both species help each other survive.

In parasitism, what is the role of the host?

• The host is the organism the parasite lives in or on, providing food or shelter but is harmed by the relationship.

• The host is the organism that benefits from the relationship, gaining nutrients from the parasite.

• The host is the organism that protects the parasite from predators and environmental threats.

• The host is the organism that completely eliminates the parasite from its system.

How do predators indirectly protect plants?

• By eating herbivores, which limits grazing and helps preserve plant populations.

• By directly consuming plants, which reduces competition among them.

• By providing nutrients to the soil through their waste.

• By attracting herbivores away from plants with their presence.

Why is predation beneficial for ecosystems?

• It increases the population of prey species.

• It helps maintain biodiversity and keeps prey populations in check.

• It leads to overgrazing of plants.

• It has no significant impact on ecosystems.

Name the five main types of symbiotic relationships.

• Predation, Competition, Parasitism, Mutualism, Commensalism

• Predation, Competition, Mutualism, Commensalism, Amensalism

• Parasitism, Commensalism, Mutualism, Competition, Symbiosis

• Predation, Commensalism, Parasitism, Competition, Neutralism

What is commensalism?

• A relationship where both species benefit.

• A relationship where one species benefits and the other is unaffected.

• A relationship where one species harms the other.

• A relationship where both species are harmed.

What is competition in an ecosystem?

• Competition occurs when organisms cooperate for resources.

• Competition occurs when two or more organisms need the same limited resource, like food, water, space, or mates.

• Competition is the process of organisms forming symbiotic relationships.

• Competition happens only between individuals of the same species.

What are the benefits of mutualism in nature?

• Mutualism allows species to compete for resources more effectively.

• Mutualism can help species survive by sharing protection, nutrition, or other resources, making both more resilient in their environments.

• Mutualism leads to the extinction of weaker species.

• Mutualism creates a dependency that harms both species in the long run.

What is symbiosis?

• A close, long-term interaction between two different species where at least one species benefits.

• A type of competition between two species for resources.

• A relationship where two species live in the same habitat without interacting.

• A short-term interaction between two species that is always harmful.
