The ecosystem and its structure

in Eshaaan

EMS-National ecosystems and human activity, page no 187

What is an ecosystem:

An ecosystem is defined as all the living things{biotic components}together with all the non-living things{abiotic components} in an area. These biotic and abiotic components interact with each other.

What is a ecosystem structure:

The living things in an ecosystem can be described at a number of different levels.

• Populations: Populations are made up of all the individuals of the same species in a area. Examples of populations include all frogs in pond, all the drongos in a forest or all the elephants in a national park.

• Communities: Communities are made up of all the species characteristics of a particular ecosystems. Examples include all the different species of animal in the Arctic tundra or all the plants in the Arctic tundra, representing the animal and plant communities respectively.

Replying to

Producers use energy and inorganic molecules to make food. Consumers take in food by eating producers or other living things. Decomposers break down dead organisms and other organic wastes and release inorganic molecules back to the environment.
Energy is transferred between organisms in food webs from producers to consumers.
Nutrient cycles keep the ecosystem in equilibrium and help in storing nutrients for future uptake.
Terrestrial ecosystems are land-based, while aquatic ecosystems are water-based.
trees, animals, plants, and other living things.
Abiotic factors help living organisms to survive. Sunlight is the energy source and air (CO2) helps plants to grow. Rock, soil and water interact with biotic factors to provide them nutrition. Interaction between biotic and abiotic factors helps to change the geology and geography of an area.
