Symbiosis - Practice

In which type of symbiotic relationship does one organism benefit while the other is harmed?

• Mutualism

• Commensalism

• Parasitism

• Competition

What is the significance of symbiotic relationships in ecosystems?

• They contribute to biodiversity and ecological balance.

• They reduce competition among species.

• They increase the population of invasive species.

• They eliminate the need for food chains.

What is an example of parasitism?

• Hookworms feeding on the blood of their host.

• Bees pollinating flowers.

• Birds building nests in trees.

• Fungi decomposing dead organic matter.

What is the impact of parasitism on the host organism?

• The host can suffer from blood loss, anemia, and iron deficiency.

• The host gains additional nutrients and energy.

• The host develops immunity to the parasite.

• The host experiences no significant changes.

What is symbiosis?

• A close relationship between two different species living together.

• A type of competition between two species for resources.

• A method of reproduction in plants.

• A process of evolution in isolated species.

What is the role of algae in the mutualistic relationship with fungi?

• Algae perform photosynthesis to provide energy.

• Algae absorb nutrients from fungi.

• Algae provide structural support to fungi.

• Algae produce toxins to protect fungi.

How do fungi benefit algae in their mutualistic relationship?

• Fungi provide a protective home and gather nutrients from rainwater.

• Fungi produce oxygen for algae to use during photosynthesis.

• Fungi absorb sunlight and convert it into energy for algae.

• Fungi compete with algae for nutrients in the environment.

What is the term for a relationship where one organism benefits and the other is harmed?

• Mutualism

• Commensalism

• Parasitism

• Symbiosis

How can understanding symbiotic relationships help in environmental conservation?

• It helps in recognizing the interdependence of species and the importance of preserving habitats.

• It allows for the exploitation of resources without concern for ecological balance.

• It promotes the idea that all species can thrive independently without interaction.

• It encourages the removal of invasive species without considering native species' roles.

What type of symbiotic relationship involves both organisms benefiting?

• Mutualism

• Commensalism

• Parasitism

• Competition
