Ecosystem Changes level 4

Analyze how human-induced climate change might alter the natural progression of succession in polar ecosystems.

• Climate change has no impact on polar succession.

• Climate change can alter temperature and ice cover, affecting succession stages.

• Climate change accelerates succession by providing more sunlight.

• Climate change only affects tropical ecosystems.

Assess the role of lichens in the early stages of primary succession.

• Lichens are the final species to colonize an area.

• Lichens break down rock to form soil, facilitating further succession.

• Lichens compete with trees for sunlight.

• Lichens prevent other species from colonizing the area.
