Biology Unit 9

5. Clearing forested land and repurposing it for non-forest use
7. - Aquatic regions where sunlight penetrates, able to support photosynthesis
8. When human populations become so large they are not able to be supported by an ecosystem
11. Biomes where fresh and saltwater meet - typically very productive areas due to influx of
12. Land ecosystems categorized by average temp and precipitation - includes tundra, grasslands, deserts, boreal forests, temperate forests, savannas, and tropical rainforests
14. Collection of ecosystems characterized with similar temps, rainfall totals, and climax communities
16. Key organisms in an ecosystem that helps stabilize or maintain that ecosystem
17. Species that evolve and are only found in one isolated geographical location
20. Long term changes in average global temps causes changes in weather patterns

1. Protec ecosystems at the bottom of the ocean near divergent plate boundaries
2. Predictable changes in an ecosystem as it progresses from pioneer on bare rock to mature community
3. First species to invade or populate an area, typically a lichen in primary succession
4. Predictable changes in an ecosystem after a disturbance as it progresses toward reestablishing a mature/climax community - some soil already exists
6. Mature form of an ecosystem, end result of biological succession
9. Aquatic regions that don't have sunlight, unable to support photosynthesis
10. Water ecosystems categorized by light availability, water depth, and salinity - includes intertidal areas, continental shelf, coral reefs, pelagic zone, benthic zone, photic zone, aphotic zone, etc.
13. Non-native species in a community, often able to outcompete endemic species - removed from limiting factors
15. Measurement of the variety and richness of an ecosystem, measured by richness, evenness
18. Visual representation of the feeding interaction in ecosystems
19. Created from a mutualistic symbiotic relationship between plant and a fungus
