Across
- 2. total amount of living tissue within a given trophic level
- 7. population growth Growth of a population in an ideal, unlimited environment, represented by a J-shaped curve when population size is plotted over time.
- 8. the study and implementation of restoring damaged ecosystems
- 9. increasing concentration of a harmful substance in organisms at higher trophic levels in a food chain or food web
- 11. competition between members of different species
- 12. the variety of life in the world or in a particular habitat or ecosystem.
- 13. The movement of abiotic factors between the living and nonliving components within ecosystems; also known as nutrient cycles (i.e., water cycle, carbon cycle, oxygen cycle, and nitrogen cycle).
- 14. population growth that levels off as population size approaches carrying capacity
Down
- 1. The pattern of reproducing when young and producing many offspring that receive little or no parental care; often seen in short-lived, small-bodied species.
- 3. A relationship between two species in which both species benefit
- 4. Graph showing the number of survivors in different age groups for a particular species.
- 5. Conditions in the environment that put limits on where an organism can live
- 6. gradual change in living communities that follows a disturbance
- 7. pattern of developing and reaching sexual maturity slowly and producing few, well-cared-for offspring
- 10. competition between members of the same species
