1. Essay on the Meaning of Ecosystem:
The term an ecosystem is originally defined by Tansley (1935). An ecosystem is defined as the network of interactions among organisms, and between organisms and their environment they can come in any size but usually encompass specific, limited spaces although according to some scientists the entire planet is an ecosystem or an ecosystem is defined as a complex, dynamic community of organisms including plants, animals and micro-organisms that all interact among themselves as well as with the environment that they live in.
An ecosystem consists of the biological community that occurs in some locale, and the physical and chemical factors that make up its non-living or abiotic environment. All living organisms are a part of both a biotic community and an ecosystem.
Ecosystems are what sustain both humans and animals, providing them with energy, nutrients, oxygen, water and shelter, among other things. Ecosystems don’t have strict boundaries or sizes; they can range from something as small as a dead tree stump to something as large as the ocean.
2. Essay on the Concept of Ecosystem:
There are many examples of ecosystems a pond, a forest, and grassland. The study of ecosystems mainly consists of the study of certain processes that link the living, or biotic, components to the non-living, or abiotic, components. Energy transformations and bio-geochemical cycling are the main processes that comprise the field of ecosystem ecology. Ecology generally is defined as the interactions of organisms with one another and with the environment in which they occur.
Studies of individuals are concerned mostly about physiology, reproduction, development or behavior, and studies of populations usually focus on the habitat and resource needs of individual species, their group behaviors, population growth, and what limits their abundance or causes extinction. Studies of communities examine how populations of many species interact with one another, such as predators and their prey, or competitors that share common needs or resources.

These functional aspects include such things as the amount of energy that is produced by photosynthesis, how energy or materials flow along the many steps in a food chain, or what controls the rate of decomposition of materials or the rate at which nutrients are recycled in the system.
3. Essay on the Functions of an Ecosystem:
Ecosystem function is the capacity of natural processes and components to provide goods and services that fulfill human needs, either directly or indirectly. Ecosystem functions are conceived as a subset of ecological processes and ecosystem structures. Each function is the result of the natural processes of the total ecological subsystem of which it is a part.
Natural processes, in turn, are the result of complex interactions between biotic (living organisms) and abiotic (chemical and physical) components of ecosystems through the universal driving forces of matter and energy.
There are four primary groups of ecosystem functions:

(i) Regulatory functions,
(ii) Habitat functions,
(iii) Production functions and
(iv) Information functions
(i) Regulatory Functions:
ADVERTISEMENTS:
The intensity of the light that reaches the earth varies according to the latitude and season of the year. The southern hemisphere receives less than 12 hours of sunlight during the period between the 21st March and the 23rd of September, but receives more than 12 hours of sunlight during the following six months.
