Explain the meanings of key terms such as biomes, ecosystems, biosphere, hydrosphere, atmosphere and lithosphere. Describe the main characteristics of a biome and ecosystem. Identify and locate the world’s major biomes. Describe the general characteristics of the world’s major biomes such as rainforests, deciduous and evergreen temperate forests, grasslands, tundra and deserts and the factors responsible for their distribution e.g. climate, soils.
Understand the Problem
The question requires defining several key geographical and ecological terms. It also asks for descriptions of biomes and ecosystems, identification and location of major global biomes, and a description of general characteristics of the world’s major biomes.
Answer
Key terms: Biosphere is all life on Earth; Biomes are large areas with similar climate, animal, and plant communities; Ecosystem is the interaction of living organisms with their environment; Lithosphere is the Earth's solid outer layer; Atmosphere is the layer of gases surrounding the Earth; Hydrosphere is all the water on Earth. \ Main biomes: rainforests, deciduous forests, evergreen forests, grasslands, tundra, and deserts.
Here are the definitions and characteristics you requested:
- Biosphere: The part of Earth where life exists, including all living organisms and their interactions with the environment (atmosphere, hydrosphere, and lithosphere).
- Biomes: Large geographic areas with similar climate conditions, animal populations, and plant species.
- Ecosystem: A community of living organisms (biotic) interacting with each other and their non-living (abiotic) environment.
- Lithosphere: The Earth's solid outer layer, including the crust and the upper part of the mantle.
- Atmosphere: The layer of gases surrounding the Earth.
- Hydrosphere: All the water on Earth, including oceans, lakes, rivers, ice, and groundwater.
Main Characteristics:
- Biome: Climate, soil, and dominant plant and animal species.
- Ecosystem: Interactions between living organisms (plants, animals, microbes) and their physical environment (air, water, soil).
World’s Major Biomes: rainforests, deciduous forests, evergreen forests, grasslands, tundra, and deserts. These biomes are distributed based on climate, latitude, altitude, and soil type.

World’s Major Biomes: rainforests, deciduous forests, evergreen forests, grasslands, tundra, and deserts. These biomes are distributed based on climate, latitude, altitude, and soil type.
More Information
Understanding these terms and biomes is fundamental to studying ecology, geography, and environmental science. Several factors determine the distribution of the world's major biomes, including climate, soils, latitude, and altitude. These factors influence the types of plants and animals that can survive in a particular area.
Tips
Students may confuse the terms biome and ecosystem. A biome is a larger geographical area characterized by specific climate conditions, while an ecosystem refers to the interactions between living organisms and their environment within a particular area.
