The biosphere is divided into biomes, which are large geographical regions defined by similar climates and the plants and animals within them. A biome is influenced by abiotic factors like temperature, precipitation, latitude, elevation, oceans, wind, and geography, which shape its biotic community of interacting organisms that depend on each other for survival, such as plants providing food and shelter for animals while animals help disperse seeds and provide the food chain. The Earth contains eight main terrestrial biomes.

1. Biomes

2. The biosphere is a thin layer of air, land, and water on or near the Earth’s surface where living things exist. If the earth was an apple, then the apple’s peel would represent the biosphere.

3. The biosphere is divided into smaller sections called biomes.

4. A biome is a large geographical region that has similar types of biotic and abiotic factors.

5. Biotic factors are living organisms within a biome.

6. Abiotic factors are non-living parts of a biome.

7. A biome is a distinct ecological community of plants and animals (biotic factors) living together within a similar climatic region (abioticfactors).

8. Temperature and precipitation are the main abiotic factors that influence the characteristics and distribution of biomes.

9. The following factors influence temperature and precipitation. Latitude Ocean Currents

10. Elevation Wind

11. Geographical features also play a role in the formation of biomes.

12. Plants and animals in a biome depend on one another for survival.

13. Plants provide food and shelter for animals.

14. Animals help spread the seeds of plants …

15. … as well as provide food for animals.

16. The Earth has eight terrestrial (land-based) biomes. Tundra Boreal Forest Temperate Deciduous Forest Temperate Rainforest Grassland (Temperate and tropical) Tropical Rainforest Desert (Hot and Cold) Permanent Ice (Polar Ice)
