Ecology is the study of the interactions between organisms and their environment.
Some broad concepts you should have in your lessons include but are not limited to...
1. Adaptation - a particular genetic change that improves an organism's ability to survive and reproduce in a certain environment
2. Evolution - genetic change in a population of organisms over time
3. Natural Selection - changes in the gene pool from generation to generation
4. Symbiosis - close relationships between two or more species
5. Abiotic Factors - nonliving factors that affect a particular species such as weather
6. Population Growth - including birth and death rates
7. Population Regulation - predator/prey, disease, human impact, etc.
8. Life Histories - reproductive patterns of a species
9. Behavior Ecology - communication and aggression
10. Competition, Habitat, and Niche - survival, location, and roles
11. Succession - change in the amount of species following a disturbance
12. Ecosystems - interacting species and environments
13. Trophic Structure - stages of energy flow
14. Nutrient Cycles - movement of nutrients on a global scale
15. You may also wish to include a small review of the biology of the cell, and some weather and climate information as well.
