| Why is biodiversity important for ecosystems? | It makes ecosystems more resilient to disturbances and changes |
| Which is a direct human impact on ecosystems? | deforestation, introducing invasive species, over-harvesting |
| How does deforestation contribute to flooding? | It removes trees that help regulate water flow and absorption |
| How does climate change impact biodiversity? | It causes changes in habitats, leading to shifts in species distribution and increased fires |
| What is meant by a "cascade effect" in ecosystems? | When one change leads to a series of other changes affecting multiple aspects of an ecosystem |
| Non-renewable energy sources | coal, oil, natural gas |
| Renewable resources (alternative energy sources) | solar, wind, water power |
| The ability of an ecological system to maintain a stable balance between its different populations and environmental factors | Homeostasis |
| Cancer causing agents (environmental contaminants) | Carcinogens |
| Example of P.P.E. | safety goggles |
