Across
- 2. spongy tissue and channels within the leaves, stems and roots of plants, allowing air to pass through, providing oxygen for growth
- 5. geological formations where water is stored underground
- 7. process of moving organic and inorganic matter throughout an ecosystem
- 10. root structures which can grow out of the ground, down from the plant's stem and even above water surfaces, allowing exposed roots to take in oxygen; also called pneumatophores
- 13. wetland vegetation slowing water, which allows sediment and other particulate material to settle on the floor of the wetland
- 15. root structures found on cypress trees which protrude above the soil
- 17. earthy material covering ground such as dirt, rocks, sand or soil
- 18. biological processes occurring naturally in the ecosystem removing contaminants
- 19. contains low oxygen
- 20. sinking or collapse of land
Down
- 1. process in which bacteria convert inorganic nitrogen (from fertilizer runoff) into harmless dinitrogen gas
- 3. speed and direction of water flow
- 4. dead material
- 6. adaptations to allow aquatic plants to root in flooded areas but maintain leaves and flowers above water to achieve photosynthesis
- 8. water-loving
- 9. habitats migratory birds will utilize to gather resources along the flyway during bi-annual migration
- 11. depth, duration and frequency of flooding
- 12. process of replenishing water stored underground in geological formations called aquifers
- 14. used to mitigate greenhouse gas emissions
- 16. areas flooded or saturated by water and support vegetation adapted for life in saturated soil conditions
