IB DP ESS 2.4 HL Addendum Questions

Front

What is upwelling?

Back

Upwelling is the process where nutrient-rich water from the deep ocean rises to the surface, supporting marine life.

Front

What role does upwelling play in ocean ecosystems?

Back

Upwelling brings nutrient-rich water to the surface, enhancing productivity and biodiversity in marine ecosystems.

Front

What are r-strategist species?

Back

R-strategist species are organisms that produce many offspring with little parental care, often thriving in unstable environments.

Front

How do r-strategist species adapt to pioneer communities?

Back

They produce many offspring with little parental care, allowing rapid population growth in newly available habitats.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize barren environments, often fast-growing and adapted to harsh conditions.

Front

What is the main characteristic of pioneer species in succession?

Back

Pioneer species are fast-growing and adapted to harsh conditions, enabling them to establish in disturbed areas.

Front

What is a plagioclimax?

Back

A plagioclimax is a community that results from human interference in ecological succession, preventing the development of a natural climax community.

Front

What is thermohaline circulation?

Back

Thermohaline circulation is the large-scale movement of water driven by differences in temperature and salinity, influencing global climate.

Front

How does thermohaline circulation influence global temperatures?

Back

Thermohaline circulation stabilizes temperatures by redistributing heat across the planet.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including species diversity, genetic diversity, and ecosystem diversity.
