Symbiotic Relationships in Biology

What is the primary benefit of symbiotic relationships in ecosystems?

• They help maintain ecological balance.

• They promote the extinction of weaker species.

• They increase competition among species.

• They reduce biodiversity.

Which type of mutualism involves both organisms being completely dependent on each other?

• Defensive mutualism

• Facultative mutualism

• Trophic mutualism

• Obligate mutualism

In which type of mutualism do organisms exchange energy or nutrients?

• Defensive mutualism

• Trophic mutualism

• Dispersive mutualism

• Obligate mutualism

What is an example of commensalism where one organism uses another as a permanent home?

• Mutualism

• Phoresy

• Metabiosis

• Inquilinism

Which type of commensalism involves one organism creating a habitat for another after its death?

• Inquilinism

• Phoresy

• Mutualism

• Metabiosis

What is the main characteristic of parasitism?

• Both organisms are harmed.

• One organism benefits while the other is harmed.

• Neither organism is affected.

• Both organisms benefit equally.

Why have parasites evolved to harm but not kill their hosts quickly?

• To increase their own lifespan.

• To ensure the host can reproduce and provide new hosts.

• To avoid detection by the host.

• To reduce competition with other parasites.

What could be a consequence of honeybees dying out?

• Increased plant diversity

• More food for animals

• Collapse of ecosystems

• Improved air quality

How can symbiotic relationships be used in ecology?

• To increase the number of predators

• To measure the health of an ecosystem

• To decrease plant growth

• To promote species extinction

What is the focus of the next lesson after symbiotic relationships?

• Climate change

• Animal behavior

• Plant physiology

• Population growth
