Biophysical Interactions

1. the animal life of an area or region.
2. a complex chain of successive seres beginning with a pioneer community and ending with a climax community.
4. the total weight of living things in a given area.
5. the place where a particular plant or animal lives.
7. the number of different species.
8. plants originally found in an area.
10. the process whereby plants collect energy from the sun and use it to combine carbon dioxide with water to produce organic nutrients.
11. The community that results when a climax community becomes modified or displaced.
13. a mutually beneficial relationship which develops between species.
18. a community of species and their non living habitat.
19. the study of interactions of living organisms with each other, their habitats and environments.
21. a group of closely allied plant or animal types that can reproduce with each other.
22. the position and function of plant or animal in its community.

1. the plant life of an area or region.
2. the sequential development of more complex plant communities. The succession may start on bare, previously uncolonised ground.
3. ecosystems of marine and fresh water environments
4. the surface zone of the earth and its adjacent atmosphere, in which the organic life exists.
6. large mammals and birds which inhabit an area.
9. the inherited variation that occurs within species populations as a result of different genes or biological combinations.
12. the variety of life, encompassing the different plants, animals and micro organisms, there genes and the ecosystems of which they form a part.
13. the development of a disclimax community once an original community has been removed or destroyed by human activities such as fires or cyclones.
14. communities of plants and animals spread broadly over the surface of the continent.
15. the end product of secession – a community that is in equilibrium with its environment.
16. natural change in the structure and species composition of a community over time.
17. the very large ecosystem made up of specific vegetation types and their associated fauna. Biomes recur on different continents in areas with similar climates.
20. a stage in the sequence of events in which a plant or animal community in an area develops over a period of time.
