Symbiosis

Front

What is symbiosis?

Back

Symbiosis is a close and long-term interaction between two different species, which can be beneficial, neutral, or harmful to one or both parties.

Front

What are the three main types of symbiotic relationships?

Back

The three main types of symbiotic relationships are mutualism, commensalism, and parasitism.

Front

Define mutualism.

Back

Mutualism is a type of symbiotic relationship where both species benefit from the interaction.

Front

Give an example of mutualism.

Back

An example of mutualism is the relationship between oxpeckers and rhinoceroses, where oxpeckers eat ticks off the rhino, benefiting both.

Front

Define parasitism.

Back

Parasitism is a type of symbiotic relationship where one species benefits at the expense of the other.

Front

Give an example of parasitism.

Back

An example of parasitism is a mistletoe plant extracting nutrients from a spruce tree, harming the tree.

Front

Define commensalism.

Back

Commensalism is a type of symbiotic relationship where one species benefits and the other is neither helped nor harmed.

Front

Give an example of commensalism.

Back

An example of commensalism is barnacles attaching to a whale; the barnacles benefit by getting a ride to feeding areas, while the whale is unaffected.

Front

What is the role of oxpeckers in mutualism?

Back

Oxpeckers feed on parasites like ticks found on large mammals, providing a cleaning service while getting food.

Front

How does parasitism affect the host organism?

Back

In parasitism, the host organism is harmed as the parasite extracts nutrients or resources, potentially leading to its decline.
