Unit 5 Review: Part A

Front

What is true predation?

Back

True predation is a biological interaction where one organism (the predator) kills and eats another organism (the prey). Example: A lion hunting a zebra.

Front

How does grazing affect plant communities?

Back

Grazing helps maintain diverse ecosystems by preventing any single plant species from dominating and promoting a variety of plant life.

Front

What is mutualism?

Back

Mutualism is a type of symbiotic relationship where both species benefit. Example: Clownfish and sea anemones.

Front

Why is mutualism important for ecosystem stability?

Back

Mutualism promotes biodiversity and stability in ecosystems by fostering interdependent relationships among species.

Front

What is facultative mutualism?

Back

Facultative mutualism is a type of mutualism where species can survive independently, unlike obligate mutualism where species rely on each other.

Front

What is parasitism?

Back

Parasitism is a relationship where one organism benefits at the expense of another, often harming the host.

Front

What is commensalism?

Back

Commensalism is a relationship where one species benefits while the other is neither helped nor harmed.

Front

What is competition in ecology?

Back

Competition occurs when two or more species vie for the same resources, such as food, space, or light.

Front

What is the difference between obligate and facultative mutualism?

Back

Obligate mutualism requires both species to survive, while facultative mutualism allows species to live independently.

Front

What role do herbivores play in ecosystems?

Back

Herbivores help control plant populations and promote plant diversity by grazing.
