- 19. Climax forest formed as a result of primary succession
- 22. Organism that eats another living organism (or part of an organism) for nutrition
- 23. Animals that live predominantly or entirely on land, as compared with aquatic animals, which live predominantly or entirely in the water, or amphibians, which rely on a combination of aquatic and terrestrial habitats
- 24. A rank immediately below a species; a population that is genetically distinguishable from other populations of the same species in a particular geographic region, capable of interbreeding successfully where ranges overlap
- 25. One of the groups used in the classification of organisms, consisting of a number of orders; for example, animals in class Mammalia all share specific characteristics

- 28. Distribution where individuals are found clustered in groups in particular parts of the habitat
- 30. Simply the process of identifying areas within an overall habitat
- 31. Protective adaptation in which one organism
- 32. A body of water or air moving in a definite direction, especially through a surrounding body of water or air in which there is less movement.
- 33. Naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids.
- 35. A straight line or narrow section through an object or natural feature or across the earth's surface, along which observations are made or measurements taken.

Down
- 1. Plants considered collectively, especially those found in a particular area or habitat.
- 2. The graphical representation of the change in population density of an organism when it initially increases slowly and then rapidly as it approaches an exponential growth rate, but then decreases and levels off as the environmental carrying capacity is reached
- 4. Not able to be obtained to the role an organism plays in a community
- 5. an invasive species is a species occurring, as a result of human activities, beyond its accepted normal distribution and which threatens valued environmental, agricultural or other social resources by the damage it causes.

- 27. Any external or internal condition that challenges the homeostasis of a cell or an organism.
- 29. A group of interdependent plants or animals growing or living together in natural conditions or occupying a specified habitat.
- 34. As competition increases and resources become increasingly scarce, populations reach the carrying capacity (K) of their environment, causing their growth rate to slow nearly to zero
- 36. The quality or degree of being saline.
- 37. Association between (or within) species that benefits both but is not essential for the survival of either
