Understanding Mutualism

The video tutorial explains mutualism, a type of interspecific interaction where both organisms benefit. It is a form of symbiosis, meaning long-term interactions between different species. Examples include the mutualistic relationship between oxpecker birds and buffalo, where birds eat ticks from buffalo skin, and zebras with gut bacteria, where bacteria help break down food while receiving nutrients.

What is mutualism?

• A symbiotic relationship where both species benefit

• An interaction where one species benefits and the other is harmed

• A relationship where one species is unaffected

• A type of competition between species

Which of the following best describes symbiosis?

• A relationship where one species is always harmed

• Interactions that occur only in aquatic environments

• Long-term interactions between different species living together

• Short-term interactions between species

How do Oxpecker birds benefit from their relationship with Buffalo?

• They obtain food by eating ticks and larvae

• They receive protection from predators

• They gain a habitat on the Buffalo's back

• They learn to migrate with the Buffalo

What benefit do Buffalo receive from Oxpecker birds?

• Increased speed

• Improved digestion

• Protection from the sun

• Cleaning of their skin

What role do bacteria play in the digestive system of zebras?

• They store excess nutrients for later use

• They provide energy through photosynthesis

• They produce toxins to deter predators

• They help break down food by producing cellulases

How do bacteria benefit from living in the zebra's intestine?

• They gain mobility to travel long distances

• They receive a stable supply of nutrients

• They are protected from external threats

• They can reproduce at a faster rate
