discuss the structural and functional aspects of ecosystem
Answers
The ecosystem is the structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interaction between organisms and their environment. The term “Ecosystem” was first coined by A.G.Tansley, an English botanist, in 1935.
Read on to explore the structure, components, types and functions of the ecosystem in the ecosystem notes provided below.
Types of Ecosystem
An ecosystem can be as small as an oasis in a desert, or as big as an ocean, spanning thousands of miles. There are two types of ecosystem:
Terrestrial Ecosystem
Aquatic Ecosystem
Terrestrial Ecosystems
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 Ecosystem
Forest Ecosystem
A forest ecosystem consists of several plants, animals and microorganisms that live in coordination with the abiotic factors of the environment. Forests help in maintaining the temperature of the earth and are the major carbon sink.
Grassland Ecosystem
In a grassland ecosystem, the vegetation is dominated by grasses and herbs. Temperate grasslands, savanna grasslands are some of the examples of grassland ecosystems.
Tundra Ecosystem
Tundra ecosystems are devoid of trees and are found in cold climates or where rainfall is scarce. These are covered with snow for most of the year. The ecosystem in the Arctic or mountain tops is tundra type.
Desert Ecosystem
Deserts are found throughout the world. These are regions with very little rainfall. The days are hot and the nights are cold.
Aquatic Ecosystem
Aquatic ecosystems are ecosystems present in a body of water. These can be further divided into two types, namely:
Freshwater Ecosystem
Marine Ecosystem
Freshwater Ecosystem
The freshwater ecosystem is an aquatic ecosystem that includes lakes, ponds, rivers, streams and wetlands. These have no salt content in contrast with the marine ecosystem.
Marine Ecosystem
The marine ecosystem includes seas and oceans. These have a more substantial salt content and greater biodiversity in comparison to the freshwater ecosystem.
Structure of the Ecosystem
The structure of an ecosystem is characterised by the organisation of both biotic and abiotic components. This includes the distribution of energy in our environment. It also includes the climatic conditions prevailing in that particular environment.
The structure of an ecosystem can be split into two main components, namely:
Biotic Components
Abiotic Components
The biotic and abiotic components are interrelated in an ecosystem. It is an open system where the energy and components can flow throughout the boundaries.
Answer:
The structural and functional aspects of the ecosystem are living organisms interact with each other and the surrounding environment.
