Study Notes
Definition of Nature
- Nature refers to the natural world, including all living and non-living things, such as plants, animals, landscapes, and weather patterns.
Components of Nature
- Biotic components: living organisms, including plants, animals, fungi, and microorganisms.
- Abiotic components: non-living factors, including water, air, soil, sunlight, temperature, and natural disasters.
Types of Ecosystems
- Terrestrial ecosystems: forests, grasslands, deserts, and tundra.
- Freshwater ecosystems: rivers, lakes, and wetlands.
- Marine ecosystems: oceans, coral reefs, and estuaries.
Natural Processes
- Water cycle: the continuous process of evaporation, condensation, and precipitation.
- Weathering and erosion: the breakdown and transportation of rocks and soil by natural forces.
- Photosynthesis: the process by which plants convert sunlight into energy.
Human Impact on Nature
- Pollution: the release of harmful substances into the environment, affecting air, water, and soil quality.
- Climate change: the warming of the Earth's atmosphere, primarily caused by human activities.
- Conservation: the preservation and protection of natural resources and ecosystems.
Importance of Nature
- Provides resources: food, water, air, and raw materials.
- Supports biodiversity: a variety of plant and animal species.
- Influences human health: through air and water quality, and access to natural spaces.
Definition and Components of Nature
- Nature encompasses the natural world, including living (biotic) and non-living (abiotic) components.
- Biotic components consist of plants, animals, fungi, and microorganisms.
- Abiotic components include water, air, soil, sunlight, temperature, and natural disasters.
Types of Ecosystems
- Terrestrial ecosystems comprise forests, grasslands, deserts, and tundra.
- Freshwater ecosystems consist of rivers, lakes, and wetlands.
- Marine ecosystems include oceans, coral reefs, and estuaries.
Natural Processes
- Water cycle: evaporation, condensation, and precipitation occur continuously.
- Weathering and erosion: rocks and soil break down and are transported by natural forces.
- Photosynthesis: plants convert sunlight into energy through this process.
Human Impact on Nature
- Pollution: harmful substances released into the environment affect air, water, and soil quality.
- Climate change: human activities primarily cause the warming of the Earth's atmosphere.
- Conservation: preserving and protecting natural resources and ecosystems.
Importance of Nature
- Nature provides resources: food, water, air, and raw materials.
- It supports biodiversity: a variety of plant and animal species exist.
- Nature influences human health: through air and water quality, and access to natural spaces.
