Study Notes
Abiotic Factors
- Sunlight is the primary energy source for ecosystems.
- Sunlight influences temperature, circadian rhythms, and photosynthesis.
- Temperature is influenced by sunlight and can affect the distribution and diversity of organisms.
- Wind distributes pollen, gases, and spores.
- Wind also moderates temperature.
- Water is a vital molecule essential for life.
- Water exists in three states: solid, liquid, and gas.
Biotic Factors
- Soil provides nutrients for plants, serving as a habitat for diverse organisms like earthworms and ants.
- Salinity, or the salt concentration in water, significantly impacts the types of organisms that can thrive in an ecosystem.
- pH levels, or the acidity or alkalinity of a solution, determine the biodiversity within an ecosystem.
- pH is essential for nutrient distribution and the growth of various organisms.
