Lecture Script: Good morning, everyone. Today, we will be discussing the impact of climate change on biodiversity. As temperatures rise globally, ecosystems around the world are facing unprecedented challenges. Climate change is affecting the distribution of species, altering habitats, and disrupting food chains. For example, in tropical rainforests, many species of plants and animals are facing extinction due to changing weather patterns and deforestation. One key aspect to consider is the relationship between rising temperatures and species migration. As temperatures increase, some species are moving towards the poles or to higher altitudes in search of cooler climates. This migration can lead to competition for resources with native species and disrupt the balance of ecosystems. Now, let's address a student question. Yes, please go ahead. How does climate change specifically impact marine biodiversity? That's a great question. Climate change affects marine biodiversity in various ways, such as ocean acidification, coral bleaching, and changes in sea levels. These factors pose significant threats to marine species, including fish, corals, and marine mammals. Questions: 1. What is the main topic of the lecture? A. Impact of Deforestation on Biodiversity B. Climate Change and Global Warming C. The Impact of Climate Change on Biodiversity D. The Relationship Between Species Migration and Climate Change 2. According to the lecture, what is one effect of climate change on tropical rainforests? A. Decrease in deforestation B. Increase in plant and animal diversity C. Extinction of species D. Expansion of habitats 3. How are rising temperatures linked to species migration? A. They lead to habitat destruction B. They cause competition for resources C. They prevent migration D. They promote species adaptation 4. What is one way in which climate change impacts marine biodiversity? A. Ocean acidification B. Increased sea levels C. Coral bleaching D. All of the above 5. According to the lecture, why are some species moving towards the poles or higher altitudes? A. To escape predators B. To find new habitats C. To avoid climate change D. To increase competition 6. What is one potential consequence of species migration due to climate change? A. Decrease in biodiversity B. Increase in ecosystem stability C. Expansion of habitats D. Decrease in global temperatures Answer Key: 1. (C) The Impact of Climate Change on Biodiversity 2. (C) Extinction of species 3. (B) They cause competition for resources 4. (D) All of the above 5.
