Symbiosis Practice

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 symbiosis?

Back

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

Front

Define mutualism.

Back

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

Front

Define commensalism.

Back

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

Front

Define parasitism.

Back

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

Front

Give an example of mutualism.

Back

An example of mutualism is the relationship between bees and flowers, where bees get nectar and flowers get pollinated.

Front

Give an example of commensalism.

Back

An example of commensalism is barnacles attaching to a whale; barnacles benefit by getting a ride to feeding areas, while the whale is not affected.

Front

Give an example of parasitism.

Back

An example of parasitism is a tapeworm living in the intestines of a mammal, where the tapeworm benefits and the host is harmed.

Front

How does mutualism differ from parasitism?

Back

In mutualism, both species benefit, while in parasitism, one species benefits at the expense of the other.

Front

What is an ecological niche?

Back

An ecological niche is the role and position a species has in its environment, including all interactions with biotic and abiotic factors.
