Homeostasis (Sea Otter) 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 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 nonliving components of an ecosystem, including temperature, water, sunlight, and minerals.

Front

How does ocean acidity affect marine life?

Back

Increased ocean acidity can harm marine organisms, particularly those with calcium carbonate shells or skeletons, such as corals and some shellfish.

Front

What is the role of carbon dioxide in water acidity?

Back

Carbon dioxide dissolves in water to form carbonic acid, which increases the acidity of the water.

Front

What is the significance of shell thickness in sea urchins?

Back

Shell thickness in sea urchins can indicate their ability to survive predation and environmental stressors.

Front

How do purple and red sea urchins differ in shell thickness?

Back

Red sea urchins generally have a greater shell thickness compared to purple sea urchins.

Front

What does a graph showing sea urchin shell thickness indicate?

Back

A graph can reveal comparative data on shell thickness between different species, helping to understand their adaptations.

Front

What is the importance of maintaining homeostasis in marine ecosystems?

Back

Maintaining homeostasis is crucial for the survival of marine organisms, as it allows them to function optimally in varying environmental conditions.

Front

What factors can disrupt homeostasis in marine environments?

Back

Factors such as pollution, climate change, and overfishing can disrupt homeostasis in marine ecosystems.
