An ecosystem is the structural and functional unit of ecology where living organisms interact with each other and their environment. The biosphere is a narrow sphere extending 8 km above and 10 km below the Earth's surface, where land, water, soil, and life interact. An ecosystem contains biotic components like producers, consumers, and decomposers as well as abiotic components including organic substances, inorganic substances, and climate factors. Ecosystems can be terrestrial like forests, grasslands, tundra, and deserts, or aquatic including freshwater and marine ecosystems. Artificial ecosystems created by humans include croplands, aquariums, parks, and zoos.

WHAT IS ECOSYSYTEM ? The ecosystem is the structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. Eg: Forests, Lakes, Deserts etc.
What is biosphere ?
Biosphere is a narrow sphere over the Earth’s surface. It has the following features : •It is less than 20 km thick and extending 8 Km above sea level and 10 km below sea level. •It is where land, water and soil interact with each other and life occurs.
Features of an ecosystem: • It is characterised by energy and matter flowing between the different elements that composes it. • Ecosystems are separated by geographical barriers. Most ecosystems tend to blend into each other. So we can call our Earth as a whole, an ecosystem.
Biotic components refer to all life in an ecosystem. They can be divided into: include all autotrophs. like Plants 2. Consumers include all heterotrphs and organisms that depend on other organisms for food include saprophytes such as fungi and bacteria.
Abiotic components are the non- living components of an ecosystem. It is divided into 3: substances such as proteins, carbohydrates and lipids. 2. Inorganic substances such as oxygen,carbon dioxide and water. 3. Climate factors like altitude,turbidity etc.

TYPES OF ECOSYSTEM:
The natural ecosystems are divided into 2: 1. Terrestrial ecosystems are exclusively land-based ecosystems. There are different types of terrestrial ecosystems distributed around various geological zones. They are as follows: • Forest ecosystems • Grassland ecosystems • Tundra ecosystems • Desert ecosystems 2. Aquatic ecosystems are ecosystems present in a body of water. They can be further divided into two: • Freshwater ecosystem: lakes,ponds,rivers • Marine ecosystems: sea,ocean
Forest ecosystem Desert ecosystem Grassland ecosystem Tundra ecosystem Freshwater ecosystem Marine ecosystem TERRESTRIAL ECOSYSTEMS AQUATIC ECOSYSTEMS
ARTIFICIAL ECOSYSTEMS: Artificial ecosystems are the man-made ecosystems such as : •Croplands •Aquarium •Parks •Kitchen Garden •Zoo
