Deserts are characterised by high temperature, bright light, colder nights and scarce animal and plant diversity.
Main deserts of the world are mainly located in the south western USA, Mexico Coastal areas of Chile and Peru (Atacama), North Africa (Sahara), South Africa (Kalahari), Asia (Tibet, Gobi, Thar) and central western Australia etc.
These ecosystems (biomes) have thick herbaceous plant cover, but have no trees These biomes are characterised by various species of grasses (family Graminae or Poaceae) Along with grasses many species of legumes (family Leguminosae) are also dominant in these biomes. These legumes make the soil nitrogen rich.
Now you have an idea of food chain and food web. Two aspects with respect to energy flow through a food chain, must be noted Energy flow 1s always in one direction (from producers to consumers).
In an ecosystem, an isolated food chain does not exist. There is an interconnection of various food chains in ecosystem. This interconnection of many food chains is called as food web, A food web expresses the pattern of energy and nutrient flow, throughout the ecosystem.
Transferred to the primary consumers (or herbivores), which directly feed on the plants. From herbivores, the energy is transferred to the next trophic level of secondary consumers (primary carnivores). The energy from secondary consumers is finally transferred to the top carnivores or tertiary consumers.
Energy 1s the capacity to do work. Without energy no work can be done. Since all living organisms Work, they constantly require energy……..
At the age of 19 i just realised that people live in a culture where people are more offended by swear words and middle fingers than they are famine, warfare and the destruction of our environment.
Decomposition of biomass and organic matter is also an important process in an ecosystem. The upper layer of Soil is the main site for decomposition processes in the ecosystem.
The rate of biomass production in an ecosystem is called its productivity.
or energy captured per unit area of land, per unit time.
Are you curious about the different types of ecosystem? Well, let’s see. There are
Life is incomplete until biotic and abiotic components of ecosystem, Biotic components of the ecosystem include microorganisms (bacteria, protozoans, algae and fungi), plants and animals. These organisms exhibit interspecific as well as intra specific relationships. Because of these relationships, the organisms interact with each other
In this segment we are going to discuss about the Components of Ecosystem and the major Abiotic Components of Ecosystem so stick around and keep reading. Components of Ecosystem | Abiotic Components of Ecosystem in 2021
Ecosystem The term Ecosystem was first proposed by A.G. Tansley Ecosystem The term Ecosystem was first proposed by A.G. Tansley inhe defined it as “the system resulting from the interaction of all the living and non living factors
When I first started to get into environmental issues, the first term that came to my mind was “”ecosystem“”. Then I learned more about it and realized it was much more than a branch of biology….
