Asked by mo
A museum exhibit explains how forests evolved and gradually changed atmospheric carbon dioxide levels over geological time. This affected global climate and influenced the evolution of other organisms. What does this illustrate about ecosystem evolution?
Question 5 options:
Individual species evolve independently without affecting other organisms or Earth systems
Forest evolution only affected plants and had no impact on animals or climate
Atmospheric changes are purely geological and never result from biological processes
Evolutionary changes in one group of organisms can have cascading effects on environment and other species

Correct answer: Evolutionary changes in one group of organisms can have cascading effects on environment and other species.
Explanation: The spread and diversification of forests changed how much CO2 was removed from the atmosphere (carbon burial, weathering), which altered climate, soils, and habitats — in turn affecting the evolution and distribution of many other organisms. The other options are false because species often interact with Earth systems and other organisms, biological processes can drive atmospheric change, and forest evolution affected far more than just plants.
