Unit 5 Homeostasis Test 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 is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What role do herbivores play in an ecosystem?

Back

Herbivores are organisms that primarily consume plants, playing a crucial role in energy transfer within the food chain.

Front

What is ocean acidification?

Back

Ocean acidification refers to the decrease in pH levels of the ocean due to the absorption of excess carbon dioxide from the atmosphere.

Front

How does carbon dioxide affect sea grasses?

Back

Increased carbon dioxide levels can enhance the growth of sea grasses, which are important for marine ecosystems.

Front

What is the greatest contributor to atmospheric carbon?

Back

Transportation is the greatest contributor to atmospheric carbon due to emissions from vehicles.

Front

What happens to the food web if a key species dies out?

Back

The extinction of a key species can disrupt the food web, leading to population declines or increases in other species.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

Front

What is the impact of pollution on marine life?

Back

Pollution can harm marine life by causing habitat destruction, toxic exposure, and disrupting reproductive systems.

Front

What is the relationship between carbon dioxide and global warming?

Back

Increased carbon dioxide levels contribute to the greenhouse effect, leading to global warming and climate change.
