Symbiosis and Invasive Species

Front

What is symbiosis?

Back

Symbiosis is a close relationship between two different species where at least one species benefits.

Front

What are the three main types of symbiotic relationships?

Back

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

Define mutualism.

Back

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

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 (the parasite) benefits at the expense of the other (the host).

Front

What is an invasive species?

Why do invasive species thrive in new environments?

Back

Invasive species thrive because they often have no natural predators in the new environment.

Front

What impact do invasive species have on native populations?

Back

Invasive species can lead to a decline or extinction of native populations by outcompeting them for resources.

Give an example of mutualism in nature.

Back

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

Front

What happens to ecosystems when invasive species are introduced?

Back

Ecosystems can become unbalanced, leading to a decline in biodiversity and changes in species interactions.
