12. A group of modern windmills.






13. Bacteria - virus - or other microorganisms that can cause disease.

27. Is the practice of planting bands of different crops across a hillside.






28. The bedrock - which lies below all of the other layers of soil - is referred to as the R horizon.

30. Being extinct or the process of becoming extinct.






31. Species that originate and live - or occur naturally - in an area or environment.






32. Says that the entropy (disorder) of the universe is increasing. One corollary of the Second Law of thermodynamics is the concept that - in most energy transformations - a significant fraction of energy is lost to the universe as heat.






33. The process by which the concentration of toxic substances increases in each successive link in the food chain.






34. A nuclear reaction in which an atomic nucleus - especially a heavy nucleus such as an isotope of uranium - splits into fragments - usually two fragments of comparable mass - releasing from 100 million to several hundred million electron volts of ener

40. The random fluctuations in the frequency of the appearance of a gene in a small isolated population - presumably owing to chance - rather than natural selection.

48. The movement of individuals into a population.






49. The development and introduction of new varieties of (mainly) wheat and rice that has increased yields per acre dramatically in countries since the 1960s.
