What is biosphere? Biosphere relatively thin life supporting stratum of earth’s surface, extending from a few kilometers into the atmosphere to the deep sea vents of the ocean.

Components of Biosphere There are two types of components in biosphere. They are the 1. Biotic Components 2. Abiotic Components

Biotic and Abiotic Components The biotic components consist of three sub-system 1. Plant system 2. Animal System 3. Micro-organisms The abiotic components are three types 1. Hydrosphere 2. Atmosphere 3. Lithosphere

What is Biome? A biome is a community of plants and animals that have common characteristics for the environment they exist in. Tropical rainforest and grassland are the common example of biome.

Grass lands

Population The whole number of inhabitants occupying an area and continually being modified by increases and losses. It is community of animals and plants etc.

Community which have an interacting group of various species in a common location.

Difference between Population & Communities

Precipitation is any type of water that forms in the earth’s atmosphere and then drops on to the surface of the Earth. The most common types of precipitation are rain hail and snow.

Water Cycle of Biosphere

Ecosystem Production

What is plant Community?

Types of vertical stratification of plant communities 1. Dominant layer 2. Shrub layer 3. Herb layer 4. Mosses or ground layer

Biotic succession The replacement of vegetation community is called biotic Succession. There are two types of biotic succession. They are – 1. Primary biotic succession 2. Secondary biotic succession

Chemosynthesis is a process certain organisms use to obtain energy for the production of food, akin to photosynthesis but without the use of sun light.

Trophic Level The different feeding level of organisms in an ecosystem are called Trophic level.
