EOC Recaps

1. EOC Recaps Plants and Ecology

2. Plant Processes Photosynthesis • Carbon dioxide and water are converted into glucose using the sun’s energy • Light dependent reactions – need the sun • Light independent – do not need sunlight

3. Plant Processes Reproduction • Sepal – outside cover over petals • Petals – protect reproductive organs; pretty • Stamen – male structure; contains pollen • Carpel – female structure; innermost structure • Stigma – holds pollen grains where they land • Style – tube from stigma to ovary • Ovary – female gametophyte formed here

4. Ecology Biomes • Determined by temperature and rainfall • When in doubt answer about rain Biotic and Abiotic Factors • Biotic – living • Abiotic – non-living

5. Ecology Cycles • Bacteria play a huge role in the breakdown of organic materials in the nitrogen, phosphorus, and carbon cycles • Cycles include: Hydrologic (water), carbon, oxygen, nitrogen, and phosphorus

6. Ecology Limiting Factors - any factors that slows or halts population growth Food Chain – one group of feeding relationships Food Web – every feeding relationship in the ecosystem Food Pyramid – shows the energy, organisms, or biomass available at each trophic level

7. Ecology Growth • Exponential growth – growth without limits • J-curve graph • Logistic growth – growth with limits • Curve levels off • Carrying capacity – maximum number of organisms an ecosystem can support

8. Succession • Primary succession – the introduction of organisms from bare rock (think volcanic eruption) • Secondary succession – the re-introduction of organisms after an upheaval (like a forest fire)
