What is one major reason many species may face extinction due to global warming?
What is one major reason many species may face extinction due to global warming?
- Higher populations of apex predators
- Increased competition among similar species
- Increased urban development blocking migration paths (correct)
- Decrease in available food sources due to flooding
How have some plants and animals already been observed to respond to warming temperatures?
How have some plants and animals already been observed to respond to warming temperatures?
- By blooming and hatching earlier in the year (correct)
- By forming new species
- By migrating to deeper oceans
- By increasing their reproductive rates
Which ecosystems are particularly at risk due to global warming?
Which ecosystems are particularly at risk due to global warming?
- Coral reefs and unique ecosystems with limited migration options (correct)
- Temperate forests due to high biodiversity
- Grasslands that cover vast areas globally
- Urban ecosystems as they adapt quickly

Flashcards
Species Range Shift
Species Range Shift
The process of species moving to new areas, often northward or upward, as their current habitats become too warm due to global warming.
Migration Barriers
Migration Barriers
The phenomenon where species are unable to migrate to suitable habitats due to barriers like cities or farmland, leading to potential extinction.
Ocean Acidification
Ocean Acidification
The increased acidity of ocean waters caused by the absorption of carbon dioxide from the atmosphere, threatening marine ecosystems like coral reefs.

Study Notes
Global Warming Impacts on Plants and Animals
- Plants and animals are struggling to adapt to global warming.
- Observed shifts include earlier blooming times for flowers and earlier hatching for birds.
- Species are migrating to higher latitudes and elevations in response to warmer temperatures.
- Human development often restricts migration pathways, increasing the risk of extinction.
- Species in unique ecosystems, unable to migrate, are particularly vulnerable.
Projected Species Extinction
- Estimating extinction rates due to global warming is challenging.
- Some scientists predict 20-50% extinction with 2-3°C warming.
- Certain species and ecosystems, such as specific forest types, may not adapt quickly.
Impacts on Ocean Ecosystems
- Ocean ecosystems, especially coral reefs, are highly susceptible.
- A single degree Celsius of warming can cause widespread coral bleaching and death.
- Increasing atmospheric carbon dioxide acidifies ocean water, further damaging ecosystems.
