Study Notes
Kelp Ecosystem
- Kelp is a vital keystone species found in North America's Pacific coast ecosystem.
- The disappearance of kelp forests would negatively impact many other species dependent on this habitat.
Predator-Prey Relationships
- Eagles, deer, bats, and coyotes exemplify predator-prey interactions.
- Deer feeding on a farmer’s garden is not classified as a predator-prey relationship.
Algae Growth and Ecosystem Pollution
- Fertilizer runoff rich in nitrogen and phosphorus promotes rapid algae growth, leading to aquatic ecosystem pollution.
Tropical Rainforest Characteristics
- Tropical rainforests receive approximately 2 meters of rainfall annually and feature a dense canopy of trees.
Deciduous Forest Flora
- Oak, maple, and beech trees are characteristic of the deciduous forest biome, where trees shed their leaves annually.
Grassland Biome Limitations
- Temperate grasslands are unable to support trees and shrubs primarily due to seasonal drought.
Biomes and Precipitation Levels
- The desert biome is characterized by low levels of precipitation affecting plant adaptations.
Beaver as a Keystone Species
- Beavers serve as keystone species by creating aquatic habitats, crucial for numerous organisms.
Ecosystem Stability Restoration
- Following an increase in prairie dog populations due to plentiful grass, the stability of the ecosystem will likely be regained when rattlesnake populations start to increase.
Primary Productivity Factors
- Tropical rainforests exhibit significantly higher primary productivity than tropical savannas due to greater precipitation levels.
Owl Adaptations in Biomes
- In grasslands, owl adaptations include abilities like digging, which differ from forest owls that possess camouflage feathers.
Climate Definition
- Climate refers to long-term weather patterns in a specific area observed over many years.
Climate vs. Weather
- Weather encompasses short-term atmospheric conditions, while climate refers to average conditions over extended periods.
Ocean Currents and Climate Impact
- Warm and cold surface ocean currents influence southern Africa's climate, with cold currents on the west coast leading to cooler temperatures there.
Factors Influencing Climate
- Climate is determined by factors such as solar energy, latitude, and the transport of heat and moisture through winds and ocean currents.
