Remediation Unit 3 Ecology Test Interaction of Organisms

Front

What is a predator?

Back

A predator is an organism that hunts and eats other organisms (prey) for food. Example: A lion is a predator that hunts zebras.

Front

What is mutualism?

Back

Mutualism is a type of symbiotic relationship where both organisms benefit from the interaction. Example: Plover birds eat parasites off crocodiles, benefiting both.

Front

What is parasitism?

Back

Parasitism is a relationship between two organisms where one benefits at the expense of the other. Example: A tick feeding on a deer.

Front

What is commensalism?

Back

Commensalism is a type of symbiotic relationship where one organism benefits and the other is neither helped nor harmed. Example: Skunks living in abandoned woodchuck burrows.

Front

What is competition in ecology?

Back

Competition occurs when two or more organisms vie for the same resources, such as food, space, or mates. Example: Blue jays competing with bluebirds for nesting sites.

Front

Define symbiosis.

Back

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

Front

What is predation?

Back

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

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic and abiotic factors.

Front

What are biotic factors?

Back

Biotic factors are the living components of an ecosystem, such as plants, animals, and microorganisms.

Front

What are abiotic factors?

Back

Abiotic factors are the non-living components of an ecosystem, such as sunlight, water, temperature, and soil.
