Homeostasis Storyline Review

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 role do alveoli play in the respiratory system?

Back

Alveoli are tiny air sacs in the lungs where gas exchange occurs; they allow oxygen to enter the blood and carbon dioxide to be expelled.

Front

What is the relationship between carbon dioxide levels and pH in the ocean?

Back

Increased carbon dioxide levels in the ocean lead to a decrease in pH, making the water more acidic.

Front

Define a keystone species.

Back

A keystone species is a species that has a disproportionately large effect on its environment relative to its abundance; its removal can lead to significant changes in the ecosystem.

Front

What is carrying capacity?

Back

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

Front

How does temperature affect plant growth?

Back

Generally, as temperature increases, plant growth also increases, up to a certain point where extreme temperatures can be detrimental.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity contributes to the resilience of ecosystems, allowing them to recover from disturbances and maintain functionality.

Front

Explain the concept of trophic cascade.

Back

A trophic cascade occurs when changes at the top of the food chain affect the population and health of species at lower levels.

Front

What is the function of the circulatory system in homeostasis?

Back

The circulatory system transports nutrients, gases, hormones, and waste products, helping to maintain homeostasis by regulating body temperature and pH.

Front

How do plants contribute to homeostasis in the environment?

Back

Plants help regulate atmospheric carbon dioxide levels through photosynthesis, contributing to the balance of gases in the atmosphere.
