Study Notes
Environmental Science
Sustainable Development
- Environmental studies contribute to sustainable development by promoting responsible resource management.
Ecosystems
- More complicated ecosystems have higher species diversity due to the requirement of diverse species for stability.
- Complexity and species diversity are related factors in ecosystems.
Abiotic and Biotic Components
- Abiotic components have an impact on organism survival, whereas biotic components are affected by changes in abiotic components.
- Abiotic components provide energy, while biotic components provide structure.
Environmental Evolution
- The concept of the environment has evolved over time, encompassing aspects such as biodiversity, forest growth, and wildlife conservation.
Population Growth
- Countries with stabilized or slowly growing populations are likely to have a steady population growth rate.
- Birth and immigration rates both contribute to population growth.
Water Resources
- Fresh surface water is predominantly found in polar ice caps and glaciers, and is not evenly distributed across all continents.
- Fresh surface water suitable for human consumption constitutes a small portion of available water resources.
Ecosystem Resilience
- Ecosystem resilience refers to the capacity of an ecosystem to recover from disturbances.
Environmental Interactions
- Physical, biological, and cultural elements interact synergistically to shape the environment.
- All three elements have a significant impact on the environment's structure and function.
Environmental Scope
- The scope of the environment includes the lithosphere, biosphere, and atmosphere.
- The atmosphere plays a crucial role in absorbing solar radiation and protecting life on Earth.
Aquatic Habitat
- Aquatic habitats of organisms include marine, brackish, and freshwater environments.
Population Regulation
- Factors regulating population growth include habitat, parasite-host relationship, predation, and food.
Climatic Factors
- Climatic factors of the abiotic environment include water currents, wind, rainfall, but not pressure.
Ecosystem Dynamics
- Pollution can lead to the development of resistance in certain species, while others may decline in numbers.
- The absence of one of the three elements (physical, biological, or cultural) can lead to an environmental crisis.
Community and Ecosystem
- A community consists of the population of plants and animals living together in a particular space.
- An ecosystem includes the community and the physical environment.
Migration and Emigration
- Migration can lead to increased genetic diversity, while emigration can lead to decreased population size.
- Immigration can lead to increased population size.
Ecosystem Functions
- The functional aspect of an ecosystem includes the flow of energy and freshwater.
- Brackish water has salinity levels between seawater and freshwater.
Abiotic Factors
- Physical factors of the abiotic environment include solar radiation, geomagnetism, light, and pressure.
- Biological factors of an ecosystem include plants, microorganisms, and animals.
Food Chain
- Primary consumers in a food chain include rabbit, deer, and grasshopper, but not hawk.
