Study Notes
Ecología
- Ecology is the scientific study of the interactions between organisms and their environment.
- It encompasses biotic (living) and abiotic (non-living) factors.
- Key ecological concepts include:
- Population ecology: examines populations of a single species.
- Community ecology: studies interactions between different species in a community.
- Ecosystem ecology: investigates the flow of energy and nutrients within an ecosystem.
- Ecological principles are essential for understanding the biodiversity and function of Earth's ecosystems.
Ecosistemas
- An ecosystem is a community of living organisms (biotic) interacting with their physical environment (abiotic).
- Ecosystems include various components:
- Producers (autotrophs): organisms that create their own food through photosynthesis (e.g., plants).
- Consumers (heterotrophs): organisms that eat other organisms (e.g., herbivores, carnivores, omnivores).
- Decomposers (saprophytes): organisms that break down dead organisms and waste products (e.g., bacteria, fungi).
- Energy flows through ecosystems in food chains and food webs.
- Nutrients cycle within ecosystems through biogeochemical cycles.
- Key characteristics can describe different ecosystems, such as forest, grassland, desert, and aquatic.
Cambio Climático
- Climate change refers to long-term shifts in temperatures and weather patterns.
- These shifts may be natural, but since the 1800s, human activities have been the main driver of climate change, primarily due to greenhouse gas emissions.
- Greenhouse gases trap heat in the atmosphere, leading to a gradual warming of the planet.
- Common greenhouse gases include carbon dioxide, methane, and nitrous oxide.
- The primary drivers of these emissions include:
- Burning fossil fuels (coal, oil, and natural gas).
- Deforestation.
- Industrial processes.
- Impacts associated with climate change include:
- Rising global temperatures.
- More frequent and intense heat waves.
- Changes in precipitation patterns.
- Melting glaciers and polar ice.
- Rising sea levels.
- Impacts affect ecosystems and human societies in various ways (e.g., disruption in agriculture, water resources, and threats to human health).
- Mitigation strategies aim to reduce greenhouse gas emissions (e.g., transitioning to renewable energy, improving energy efficiency, sustainable land management).
- Adaptation strategies focus on adjusting to the unavoidable impacts of climate change (e.g., developing drought-resistant crops, improving flood defenses).
