Question

8 which of the following examples illustrates how climate can impact ecological systems? multiple choice warmer temperatures expand growing seasons resulting in more reproductive opportunities for plants like the pasque flower native species are well adapted to local environmental conditions and can more easily evolve to persist in their present areas than invasive species increases in carbon dioxide fuels photosynthesis in species like the hemlock tree, providing more food for deer and other herbivores ocean acidification inhibits the ability of many marine organisms, like zooplankton, to make shells, which can impact fish and whales that rely on these organisms for food

Explanation:

• Option 1: Warmer temperatures (a climate - related factor) expand growing seasons (a change in the ecological system's temporal aspect) and lead to more reproductive opportunities for plants. This shows a direct impact of climate (temperature) on an ecological system (plant reproduction).
• Option 2: This is about the adaptability of native species compared to invasive species. It is more about species competition and adaptation rather than a direct climate - impact on the ecological system.
• Option 3: Increase in carbon dioxide (a greenhouse gas related to climate change) fuels photosynthesis. This is a climate - related factor (carbon dioxide levels) affecting plant (hemlock tree) growth and then the food availability for herbivores. It shows a climate - impact on the ecological system.
• Option 4: Ocean acidification (a climate - change - related phenomenon as it is due to increased carbon dioxide absorption by the ocean) inhibits the ability of marine organisms to make shells. This impacts the food chain (fish and whales that rely on these organisms). It shows a climate - impact on the ecological system.

Answer:

All of the options (1, 3, 4) illustrate how climate can impact ecological systems. Option 2 is not a direct illustration of climate impact on ecological systems.
