How do adaptations like salt glands serve species in challenging environments?
How do adaptations like salt glands serve species in challenging environments?
- They allow organisms to survive by managing environmental stressors (correct)
- They promote migration during resource shortages
- They enhance reproductive success during favorable conditions
- They increase competition for resources among species
What role does Spartina alterniflora play in salt marsh communities?
What role does Spartina alterniflora play in salt marsh communities?
- It absorbs excess freshwater to improve drainage
- It competes directly with all other plant species
- It serves as a primary predator of herbivores in the ecosystem
- It stabilizes sediments and facilitates the establishment of other species (correct)

Study Notes
Ecology as a Messy Science
- Ecology is unpredictable due to complex interconnections among ecological relationships
- Individual organisms adapt to environmental constraints, often requiring trade-offs (e.g., Spartina alterniflora in salt marshes has salt glands and aerenchyma)
- Ecological niches define where a species can live, while competition and predation refine the niche
- Population dynamics are shaped by density, distribution, resource availability, leading to non-linear outcomes and fluctuations
- Community interactions (competition, mutualism, predation) generate dynamic systems involving both living and non-living factors
- Predator-prey dynamics involve direct and indirect effects, reshaping plant communities through consumption of biomass and altering competition among species
- Co-evolution, population cycles, and feedback loops underscore ever-changing ecosystem dynamics
- Shifting variables, feedback mechanisms, and interdependencies in ecology make simple explanations difficult
- Ecology embraces complexity, finding meaning in the interplay of factors from resource fluctuations to species interactions
- Ecology strives to understand how ecosystems function and maintain balance
