Study Notes
Ecosystems
- Ecosystems are natural systems with interconnected relationships.
- Specific examples like UK oak woodlands are used to illustrate the concept.
- Producers convert water, carbon dioxide, minerals, and sunlight into organic molecules.
- Producers in oak woodlands include oak trees, consumed by insects and mammals.
- Producers are primarily plants.
- Consumers eat producers or other consumers to obtain energy.
- Consumers need to eat lots to gain sufficient energy.
- Consumers such as foxes and deer in an oak woodland help regulate populations.
- Decomposers obtain energy by breaking down dead organic material.
- Decomposers, like mushrooms and some insects, in an oak woodland break down complex organic molecules into simpler ones (e.g., water, carbon dioxide).
- Food chains show which organism eats another.
- Two types of food chains are: grazing (starts with plants), and detrital (starts with dead organic matter).
- Food webs combine multiple food chains, showing interconnected energy transfer.
Nutrient Cycling
- Nutrient cycles (or ecological recycling) involve the movement of organic and inorganic matter.
- Energy flow is unidirectional and non-cyclic.
- Mineral nutrient movement is cyclic.
- Examples of mineral cycles include carbon, sulfur, nitrogen, water, phosphorus, and oxygen cycles.
Ecosystem Balance
- Energy flow and nutrient cycling need to be constant to maintain equilibrium.
- Green plants capture sunlight to convert substances from water, air, and rocks into living matter.
- Any alteration in balance triggers chain reactions affecting the entire system.
- Removing plants can lead to more floods, harming consumers.
Biomes (Global Ecosystems)
- Tundra is a treeless polar desert (-34°C to -6°C, 150-200mm rainfall).
- Taiga has low annual temperatures (-10°C to slightly above 0°C, 40-100cm precipitation) and is dominated by conifer trees.
- Temperate grasslands have sparsely populated trees, low precipitation (500-900mm per year), and wide temperature range (-20°C to 30°C).
- Temperate deciduous forests have moderate temperatures (50°F/10°C) and 750-1500mm of rain annually with distinct seasons.
- Savannahs are grasslands with scattered trees and shrubs, with distinct rainy (15-25 inches) and dry seasons.
- Deserts have low precipitation (50cm maximum) with hot and dry, semiarid, coastal, and cold types.
Tropical Rainforests
- Tropical rainforests are located between 20-25 degrees north and south of the equator, receiving high rainfall and heat.
- Constant warm temperatures and high humidity lead to plant and animal diversity.
- High biodiversity, but also high extinction rates.
Economic and Environmental Impacts
- Subsistence farming involves growing crops for household use, often with lower environmental impact.
- Commercial farming (e.g., cattle ranching, soy) results in more significant deforestation and environmental damage due to large-scale processes and release of harmful gases.
- Deforestation results in habitat loss, biodiversity decline, and increased greenhouse gas emissions.
- Logging removes trees, leading to habitat destruction, soil erosion, and increased greenhouse gas concentrations.
- Mineral extraction can cause deforestation and environmental damage.
- Energy development (oil and hydroelectric dams) can affect landscapes, habitats, and water flow.
Sustainable Management Strategies
- Selective logging removes specific trees, leaving the rest intact for biodiversity conservation and forest regeneration.
- Replanting or reforestation restores cleared or damaged forest ecosystems.
- Ecotourism encourages sustainable use of natural resources by creating jobs for local communities.
- International agreements, such as the International Tropical Timber Agreement, promote sustainable forest management.
- Debt-for-nature swaps encourage environmentally friendly practices in exchange for reduced debt.
