Unit 3: Homeostasis

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can support sustainably.

Front

What is the difference between exponential growth and logistic growth?

Back

Exponential growth occurs when a population grows at a constant rate without limitations, while logistic growth occurs when growth slows as the population approaches carrying capacity.

Front

What is commensalism?

Back

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

Front

What is an example of mutualism?

Back

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

Front

What is predator-prey relationship?

Back

A predator-prey relationship is an interaction where one organism (the predator) hunts and eats another organism (the prey).

Front

What happens during a population die-off?

Back

A population die-off occurs when the number of individuals in a population decreases rapidly, often due to resource depletion or environmental changes.

Front

What is the role of feedback mechanisms in homeostasis?

Back

Feedback mechanisms are processes that help maintain homeostasis by detecting changes and initiating responses to counteract those changes.

Front

What is an example of a negative feedback loop?

Back

An example of a negative feedback loop is the regulation of body temperature, where the body cools down when overheated.

Front

What is the significance of biodiversity in ecosystems?

Back

Biodiversity contributes to ecosystem resilience, stability, and the ability to adapt to changes.
