This includes what it eats, where it lives, how it behaves, and how it contributes to the ecosystem.<\/span><\/p>\n<h2><b>About Ecological Niche<\/b><\/h2>\n<ul>\n<li><span style=\"font-weight: 400;\">An Ecological Niche refers to the unique role, position, and way of life of a species within its ecosystem. It explains <\/span><b>how a species survives, grows, and interacts with its surroundings.<\/b><\/li>\n<li><span style=\"font-weight: 400;\">In simple words, <\/span><b>a niche is like the \u201cjob\u201d or \u201cfunction\u201d of an organism in nature,<\/b><span style=\"font-weight: 400;\"> including everything it does to live.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">It includes not just the place where an organism lives, but also<\/span><b> how it uses resources, how it behaves, and how it affects other organisms.<\/b><\/li>\n<li><span style=\"font-weight: 400;\">The concept of Ecological Niche was introduced by <\/span><b>Charles Elton,<\/b><span style=\"font-weight: 400;\"> who described it as the functional role of a species in an ecosystem.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">It includes:<\/span>\n<ul>\n<li><span style=\"font-weight: 400;\">What resources a species uses<\/span><\/li>\n<li><span

<\/span><b>physical location of the organism, <\/b><span style=\"font-weight: 400;\">such as forests, deserts, rivers, or soil.<\/span><\/li>\n<li><b>Food habits (what it eats):<\/b><span style=\"font-weight: 400;\"> It includes the <\/span><b>type of food an organism consumes, <\/b><span style=\"font-weight: 400;\">whether it is a producer, consumer, or decomposer, and the organisms it competes with for food.<\/span><\/li>\n<li><b>Reproductive pattern: <\/b><span style=\"font-weight: 400;\">This explains <\/span><b>how, when, and where a species reproduces<\/b><span

competition, parasitism, and mutualism.<\/span><\/li>\n<\/ul>\n<\/li>\n<li><b>Importance of Ecological Niche<\/b>\n<ul>\n<li><span style=\"font-weight: 400;\">Ecological Niche plays a very important role in the<\/span><b> conservation and protection of species,<\/b><span style=\"font-weight: 400;\"> as it helps us understand the exact requirements needed for their survival.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">If we want to conserve a species in its natural habitat, <\/span><b>it is essential to maintain all aspects of its niche,<\/b><span style=\"font-weight: 400;\"> including food availability, shelter, and suitable environmental conditions.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">It also <\/span><b>helps scientists understand the interrelationship between organisms<\/b><span style=\"font-weight: 400;\"> and their environment, including <\/span><b>both living (biotic) and non-living (abiotic) components.<\/b><\/li>\n<\/ul>\n<\/li>\n<li><b>Role of Niche in <\/b><a href=\"https:\/\/vajiramandravi.com\/upsc-exam\/ecosystem\/\" target=\"_blank\"><b>Ecosystem<\/b><\/a><b> Functioning<\/b>\n<ul>\n<li><span style=\"font-weight: 400;\">A niche explains <\/span><b>how a species responds to the availability of resources<\/b><span style=\"font-weight: 400;\"> and how it is affected by factors such as predators, parasites, diseases, and competition.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">When resources are abundant and threats are low, species tend to grow and reproduce more successfully.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">At the same time, species also influence their environment by:<\/span>\n<ul>\n<li><span style=\"font-weight: 400;\">Consuming resources and limiting their availability to others<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Acting as prey for predators and helping maintain food chains<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Controlling populations of other organisms<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<li><b>Uniqueness of Niche<\/b>\n<ul>\n<li><span style=\"font-weight: 400;\">Each <\/span><b>species has its own unique Ecological Niche,<\/b><span style=\"font-weight: 400;\"> which means no two species can have exactly the same role and resource use pattern for a long time.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Even if species appear similar, they usually differ in some aspect such as feeding time, habitat use, or behavior, which allows them to coexist.<\/span><\/li>\n<\/ul>\n<\/li>\n<li><b>Formation of Ecological Niche<\/b>\n<ul>\n<li><span style=\"font-weight: 400;\">The formation of a niche is <\/span><b>influenced by both abiotic factors <\/b><span style=\"font-weight: 400;\">(such as <\/span><strong><a href=\"https:\/\/vajiramandravi.com\/current-affairs\/climate-change\/\" target=\"_blank\">climate<\/a><\/strong><span style=\"font-weight: 400;\">, soil, and temperature) and<\/span><b> biotic factors<\/b><span style=\"font-weight: 400;\"> (such as competition, predation, and food availability).<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Through the process of natural selection, <\/span><b>species develop special adaptations<\/b><span style=\"font-weight: 400;\"> that help them <\/span><b>survive and function efficiently in their specific environment.<\/b><\/li>\n<li><span style=\"font-weight: 400;\">Over time, these adaptations <\/span><b>become more specialized, making the species well-suited to its niche.<\/b><\/li>\n<\/ul>\n<\/li>\n<li><b>Example: Xerophytic Plants<\/b>\n<ul>\n<li><span style=\"font-weight: 400;\">Xerophytic plants are those that live in dry and arid conditions, where water is scarce, and they have developed special adaptations to survive in such niches.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">These plants conserve water through several features such as:<\/span>\n<ul>\n<li><span style=\"font-weight: 400;\">A thick waxy coating (cuticle) to reduce evaporation<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Reduced or modified leaves (like spines) to minimize water loss<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Thick or hairy leaf surfaces to protect against heat<\/span><\/li>\n<\/ul>\n<\/li>\n<li><span style=\"font-weight: 400;\">Some plants, especially succulents, show a special adaptation where they open their stomata at night and close them during the day, reducing water loss in hot conditions.<\/span><\/li>\n<\/ul>\n<\/li>\n<li><b>Niche and Ecosystem Stability: <\/b><span style=\"font-weight: 400;\">The stability of an ecosystem depends on the <\/span><b>diversity of niches present within it.<\/b><span style=\"font-weight: 400;\"> Greater niche diversity leads to:<\/span>\n<ul>\n<li><span style=\"font-weight: 400;\">Better and more efficient flow of energy<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Reduced competition for the same resources<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Less fluctuation in species populations<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Overall greater ecosystem stability<\/span><\/li>\n<\/ul>\n<\/li>\n<li><b>Competitive Exclusion Principle: <\/b><span style=\"font-weight: 400;\">According to the<\/span><b> Law of Competitive Exclusion,<\/b> <b>two species cannot occupy the exact same niche for a long time<\/b><span style=\"font-weight: 400;\"> if they compete for the same resources. In such situations, one species may:<\/span>\n<ul>\n<li><span style=\"font-weight: 400;\">Move to a different niche (migration)<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Adapt by changing its behavior or habits<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Become extinct if unable to compete<\/span><\/li>\n<\/ul>\n<\/li>\n<li><b>Resource Partitioning: <\/b><span style=\"font-weight: 400;\">To avoid direct competition, <\/span><b>species often divide resources among themselves,<\/b><span style=\"font-weight: 400;\"> a process known as<\/span><b> resource partitioning.<\/b><span style=\"font-weight: 400;\"> This allows different species to use the same resource in different ways, such as:<\/span>\n<ul>\n<li><span style=\"font-weight: 400;\">Feeding at different times<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Using different parts of the habitat<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Consuming different types of food<\/span><\/li>\n<li><span style=\"font-weight: 400;\">This helps multiple species coexist within the same ecosystem.<\/span><\/li>\n<\/ul>\n<\/li>\n<li><b>Dominant vs Less Dominant Species<\/b>\n<ul>\n<li><b>Dominant species<\/b><span style=\"font-weight: 400;\"> usually have a <\/span><b>broader Ecological Niche,<\/b><span style=\"font-weight: 400;\"> meaning they can use a wide range of resources and tolerate different environmental conditions.<\/span><\/li>\n<li><b>Less dominant species<\/b><span style=\"font-weight: 400;\"> have a <\/span><b>narrower niche, <\/b><span style=\"font-weight: 400;\">meaning they are more specialized and depend on specific conditions for survival.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h2><b>Difference Between Niche and
