Across
- 3. deep in pits of marram grass
- 8. all organisms within a band usually between 0.5 m and 1 m, are sampled along an environmental gradient. Used when there is a gradual change from one side of a habitat to another
- 11. is the branch of biology that deals with the relationships between organisms and their interactions with their physical surroundings
- 12. reefs, have a mutualistic relationship with Zooxanthellae.
- 14. reduces transpiration
- 15. a tape is laid out in the direction of an environmental gradient and all organisms touching the tape are recorded.
- 16. is a group of organisms capable of reproducing with each other to produce fertile offspring.
- 19. vertical root brunches that grow up into the air and can absorb oxygen.
- 20. is formed by populations of different species living and interacting with each other in a habitat.
Down
- 1. is a place where an organism lives and a description of the geographical location, the type of ecosystem and the physical location within the ecosystem.
- 2. Temperatures are low with short summers and precipitation low to medium mostly as snow and light intensity low.
- 4. forests with moderate temperatures with warm summers and cold winters. rainfall medium to high and light intensity is moderate
- 5. large naturally occurring communities of organisms occupying a major habitat
- 6. grow out in a downwards arch from the central trunk to butress the tree in the soft mud.
- 7. so its stomata are all facing inwards, this causes water vapour to be trapped so that less water is lost through transpiration
- 9. on the leaves secrete excess salt from mangrove trees
- 10. describes the characteristics of the geographical area where the habitat is found
- 13. a graphical model that shows the relationship between temperature, precipitation and ecosystem type.
- 17. arbitrary line through a habitat selected to systematically sample the community.
- 18. consists of one species in one location at one time.
