All organisms such as plants, animals, microorganisms and human beings as well as the physical surroundings interact with each other and maintain a balance in nature. All the interacting organisms in an area together with the non-living constituents of the environment form an ecosystem.

What is an Ecosystem?

A pond, lake, desert, grassland, meadow, forest etc. The non living factors or the physical environment prevailing in an ecosystem form the abiotic components. They have a strong influence on the structure, distribution, behaviour and inter-relationship of organisms. Soils are much more complex than simple sediments. The vegetation found growing on top of a soil is closely linked to this component of an ecosystem through nutrient cycling. Sunlight is also necessary for photosynthesis. Water is the medium by which mineral nutrients enter and are trans-located in plants.

An organism is always in the state of perfect balance with the environment. The environment literally means the surroundings. The environment refers to the things and conditions around the organisms which directly or indirectly influence the life and development of the organisms and their populations. Organisms and environment are two non-separable factors. Organisms interact with each other and also with the physical conditions that are present in their habitats.

The functional attributes of the ecosystem keep the components running together. Ecosystem functions are natural processes or exchange of energy that take place in various plant and animal communities of different biomes of the world. For instance, green leaves prepare food and roots absorb nutrients from the soil, herbivores feed on the leaves and the roots and in turn serve as food for the carnivores. Decomposers execute the functions of breaking down complex organic materials into simple inorganic products, which are used by the producers. Fundamentally, ecosystem functions are exchange of energy and nutrients in the food chain. These exchanges sustain plant and animal life on the planet as well as the decomposition of organic matter and the production of biomass. All these functions of the ecosystem take place through delicately balanced and controlled processes.

Ecosystem: Structure, Functions & Components

We have loaded Previous years questions with explanations Like and Follow us on Facebook and Telegram for latest updates As already discussed in the previous article, Ecosystem is the structural and functional unit of ecology where living organisms interact with each other and also with the surrounding physical environment. In other words, it is the whole community in which plants and animals live together. For example, Tropical rain forest with its trees, animals etc. In the year , AG Tansley coined the term ecosystem.

An ecosystem, a term very often used in biology, is a community of plants and animals interacting with each other in a given area, and also with their non-living environments. The ecosystem relates to the way that all these different organisms live in close proximity to each other and how they interact with each other. For instance, in an ecosystem where there are both rabbits and foxes, these two creatures are in a relationship where the fox eats the rabbit in order to survive. This relationship has a knock-on effect with the other creatures and plants that live in the same or similar areas. For instance, the more rabbits that foxes eat, the more the plants may start to thrive because there are fewer rabbits to eat them.

Ecosystem : Structure and function. Organisms interact with each other and also with the physical conditions that are present in their habitats. Tansley Ecosystem is the major ecological unit. It has both structure and function. The structure is related to species diversity. Odum , the ecosystem is the basic functional unit of organism and their environment interacting with each other.


are abiotic components of the ecosystems. Functions of an Ecosytem. Ecosystem function is the capacity of natural processes and components to provide goods.


Ecosystem: Structure, Functions & Components

Forest Condition in a Changing Environment pp Cite as. Forest ecosystems consist of organisms plants, animals and micro-organisms and their habitats the soil and air. The functioning of forest ecosystems is characterised by energy and nutrient flows and cycling, biomass production and the decomposition of dead organic matter. Plants need nutrients and carbohydrates for biomass production and for other vital functions. Carbohydrates are produced by photosynthesis from carbon dioxide, water and nutrients.

Ecosystem , the complex of living organisms, their physical environment , and all their interrelationships in a particular unit of space.

Несмотря на разногласия со Стратмором по многим вопросам, Фонтейн всегда очень высоко его ценил. Стратмор был блестящим специалистом, возможно, лучшим в агентстве. И в то же время после провала с Попрыгунчиком Стратмор испытывал колоссальный стресс.

Затем взял ботинки и постучал каблуками по столу, точно вытряхивая камешек. Просмотрев все еще раз, он отступил на шаг и нахмурился. - Какие-то проблемы? - спросил лейтенант. - Да, - сказал Беккер.  - Мы кое-что упустили.

Звук выстрела продолжал звучать у нее в голове. Горячий пар пробивался через люк подобно вулканическим газам, предшествующим извержению. Проклиная себя за то, что не забрала у Стратмора беретту, она пыталась вспомнить, где осталось оружие - у него или же в Третьем узле. Когда глаза Сьюзан немного привыкли к темноте, она посмотрела на дыру, зияющую в стеклянной стене.
