Biosfer

• Definisi:

  • Biosfer adalah lapisan tipis di permukaan Bumi yang mampu mendukung kehidupan.
  • Termasuk semua ekosistem di darat dan perairan.

• Komponen Biosfer:

  • Organisme Hidup:
    • Tumbuhan, hewan, jamur, dan mikroorganisme.
  • Lingkungan Fisik:
    • Termasuk tanah, air, dan atmosfer yang mendukung kehidupan.

• Fungsi Biosfer:

  • Menyediakan sumber makanan, oksigen, dan bahan baku.
  • Menjaga keseimbangan ekosistem melalui interaksi antara organisme.

• Zonasi Biosfer:

  • Bioma: Unit ekologis besar dengan karakteristik iklim dan flora/fauna tertentu.
  • Contoh bioma: hutan hujan tropis, gurun, tundra, savana.

• Proses Ekologis:

  • Jaringan Makanan: Rantai makanan dan jaring-jaring makanan.
  • Siklus Nutrisi: Siklus karbon, nitrogen, dan air.

• Ancaman terhadap Biosfer:

  • Perubahan iklim, deforestasi, pencemaran, dan kehilangan keanekaragaman hayati.
  • Aktivitas manusia yang dapat merusak keseimbangan ekologis.

• Keselamatan Biosfer:

  • Perlunya upaya konservasi dan keberlanjutan.
  • Peran pendidikan lingkungan untuk meningkatkan kesadaran masyarakat.

• Keterkaitan dengan Ilmu Lain:

  • Biologi, ekologi, geografi, dan ilmu lingkungan studi tentang biosfer dan interaksinya.

Biosfer Definition

• The biosfer is the thin layer on Earth's surface that supports life.
• It includes all terrestrial and aquatic ecosystems.

Biosfer Components

• Living Organisms:
  • Plants, animals, fungi, and microorganisms.
• Physical Environment:
  • Includes soil, water, and atmosphere that sustains life.

Biosfer Functions

• Provides food, oxygen, and raw materials.
• Maintains ecosystem balance through interactions between organisms.

Biosfer Zonation

• Biomes:
  • Large ecological units with specific climate and flora/fauna characteristics.
  • Examples: tropical rainforests, deserts, tundras, savannas.

Ecological Processes

• Food Webs:
  • Food chains and food webs.
• Nutrient Cycles:
  • Carbon, nitrogen, and water cycles.

Threats to Biosfer

• Climate change, deforestation, pollution, and biodiversity loss.
• Human activities that can disrupt ecological balance.

Biosfer Safety

• Conservation and sustainability efforts are crucial.
• Environmental education plays a vital role in raising public awareness.

Connections with Other Sciences

• Biology, ecology, geography, and environmental science study the biosfer and its interactions.
