Chapter 5, Populations
Across
- 1. The movement of individuals out of an area, can cause a population to decrease in size
- 4. These activities such as deforestation,damming rivers and using resources, are a limiting factor.
- 7. this relationship is the regulation of a population by predation, and example are the wolf and moose population in Isle Royale.
- 8. The largest amount of individuals an environment can support and the number the population hits when it reaches logistic growth
- 10. This limiting factor affects all populations in similar ways regardless of population size, some examples are unusual weather, and natural disaster
- 12. Number of individuals per unit area
- 13. A factor that causes population growth to decrease, such as competition,Predation, Disease or natural disasters
Down
- 2. The movement of individuals into a given area
- 3. when animals compete with each other for food
- 5. Take nourishment in expense to their host, limit the growth of the population, and range in size from microscopic to 30cm+ in length
- 6. This type of growth occurs when a populations growth slows or stops following a period of exponential growth
- 9. This limiting factor becomes limiting only when the population density reaches a certain level.These include competition, predation, parasitism and disease.
- 11. This type of growth occurs when the individuals in a population reproduce at a constant rate, and continually.
