Study Notes
Biome Ecosystems
- Biomes consist of ecosystems that share similar biotic (living) and abiotic (non-living) factors.
African Biomes
- Major biomes in Africa include desert, savanna, and chaparral.
South African Ecosystems
- The succulent thicket in South Africa features grasses and short, fleshy plants.
Abiotic Influences on Biomes
- Temperature and rainfall are the primary abiotic factors influencing biome classification.
Latitude and Biomes
- Latitude affects biomes through temperature variations and atmospheric circulation patterns.
Climatographs and Biomes
- Climatographs illustrate the moisture levels of a biome, indicating whether it is dry or moist.
Role of Natural Selection
- Natural selection is crucial for the survival and reproduction of organisms best adapted to their environments.
Adaptation in Biomes
- Different biomes host distinct organisms because species adapt to their specific environmental conditions.
Variation Within Biomes
- Variability in plant and animal communities can arise from local factors such as soil type, elevation, or wind exposure.
Net Primary Production
- Net primary production refers to the biomass left after accounting for the energy used in cellular respiration.
Gross vs. Net Primary Production
- Gross primary production encompasses all energy converted by primary producers, while net primary production is the remaining biomass after energy loss.
