The functions of an ecosystem

 

The functions of an ecosystem refer to the natural processes and interactions that sustain life, regulate the environment, and support biodiversity. These functions are essential for the health of the planet and human well-being. The main functions of an ecosystem can be grouped into four broad categories:


1. Regulating Functions

These maintain environmental conditions within certain limits:

  • Climate regulation (e.g., forests sequester carbon, influencing global temperatures)

  • Water purification (e.g., wetlands filter pollutants from water)

  • Pollination (e.g., insects pollinate crops and wild plants)

  • Disease control (e.g., predators control populations of disease-carrying species)


2. Supporting Functions

These are necessary for the production of all other ecosystem services:

  • Nutrient cycling (e.g., decomposition of organic matter returns nutrients to the soil)

  • Soil formation and maintenance (e.g., organisms break down rock and organic material into fertile soil)

  • Primary production (e.g., plants converting sunlight into energy via photosynthesis)


3. Provisioning Functions

These provide humans with essential materials:

  • Food production (e.g., crops, livestock, fish)

  • Freshwater supply

  • Raw materials (e.g., timber, fiber, fuel)

  • Medicinal resources (e.g., plants used for pharmaceuticals)


4. Cultural Functions

These offer non-material benefits:

  • Recreational and tourism opportunities (e.g., national parks)

  • Spiritual and religious value

  • Educational and scientific value

  • Aesthetic appreciation

Ecology in the Indian Knowledge System (IKS)

 

 Ecology in the Indian Knowledge System (IKS)

Indian Knowledge System (IKS) promotes a deep and respectful relationship between humans and nature. Ecological wisdom is not a separate subject in IKS—it is deeply interwoven into philosophy, religion, lifestyle, and traditional practices.


Key Ecological Concepts in IKS

1. Nature as Sacred

  • Prakriti (Nature) is considered divine.

  • Elements like earth (Bhumi), water (Jala), fire (Agni), air (Vayu), and space (Akasha) are seen as sacred and worshipped as Panchamahabhutas (five great elements).

  • Trees like the Peepal, rivers like the Ganga, and mountains like the Himalayas are revered, which fosters protection and respect for nature.

2. Concept of Dharma and Balance

  • Ecological balance is part of Dharma (duty/righteousness).

  • Humans are not above nature but a part of the interdependent web of life (Lokasamgraha).

  • Traditional practices emphasize minimal consumption and sustainable living.

3. Traditional Agricultural Practices

  • Use of organic farming, crop rotation, rainwater harvesting, and natural pest control.

  • Knowledge of lunar cycles and seasonal rhythms guides planting and harvesting.

  • Examples: Vrikshayurveda (ancient science of plant life), use of cow dung and urine in farming.

4. Sacred Groves and Biodiversity Conservation

  • Sacred groves (called Devrai in Maharashtra or Sarpakavu in Kerala) are patches of forest preserved due to religious beliefs.

  • These groves act as biodiversity hotspots and help maintain ecological balance.

5. Water Management Systems

  • Ancient India had advanced water harvesting and management systems like stepwells (baolis), tanks, and canals.

  • Example: Johads in Rajasthan, Kunds in Gujarat.

6. Ayurveda and Ecological Ethics

  • Ayurveda uses natural herbs and supports ecosystem health.

  • It promotes the ethical use of plants, understanding their role in the larger environment.


Modern Relevance of IKS in Ecology

  • Climate change and environmental degradation make the eco-centric view of IKS highly relevant today.

  • IKS encourages local solutions, community-based conservation, and sustainable development.

  • Revival of IKS ecological wisdom can help build a more resilient and nature-friendly society.


Quotes & Teachings

  • "Vasudhaiva Kutumbakam"The world is one family – highlights global ecological interconnectedness.

  • Bhagavad Gita (3.14) – "All beings are born from food, food is produced by rain, rain is produced by sacrifice, and sacrifice is rooted in duty" – indicates the cycle of nature and human responsibility.

Genetics : Law of Independent Assortment

 

Law of Independent Assortment

The law of independent assortment states that the allele of different genes are inherited independently within the organisms that reproduce sexually.

 

    According to the law of independent assortment, the alleles of two or more genes get sorted into gametes independent of each other. The allele received for one gene does not influence the allele received for another gene.

Mendel’s experiment always portrayed that the combinations of traits of the progeny are always different from their parental traits. Based on this, he formulated the Law of Independent Assortment.

Need of environment friendly incense sticks

 

Need of environment friendly incense sticks

Incense stick is a trade product. It is burnt for fragrance. In India it is called as agarbatti. Now a day it is also called as Dhup Kandi. Traditionally incense sticks are used for worship, meditation, prayer, ceremonies, ritual purification, air fresheners, mosquito repellent and for creation of ambiance (Sinha and Deb, 2016).  These are also used for aroma therapy and as ayurvedic treatment. Dhup crystals are also used for the same purposes. Along with ajwain seeds (Trachyspermum ammi), dhup is burnt to treat cold in children. In Maharashtra the fumes of Dhup and ajwain seeds are used to baby after bath.

In India Agarbatti industry strongly depends on forest products like bamboo sticks and sticky powder known as jigat. Sticky powder is mainly obtained from the bark of some trees. Bamboos and the trees yielding gum or jigat are depleting very fast (Sinha and Deb, 2016; Hazarika et al., 2018). Therefore, searching for sound alternatives is essential.

Dhoop crystals, ajwain seeds, sandal wood powder and rose water are found to be good alternatives.

            The incense sticks or Dhoop batties are presented mainly in the form of sticks. The material with mosquito repellent potential is presented in the form of a coil.

            Charcoal powder, charcoal powder+ rice husk and charcoal powder + saw dust in 2:1 proportion is used. As a binding material paste of wheat flour and cow dung is used separately for all the three burning material combinations. Burning material and binding material affect the surface of agarbatties. Charcoal powder with both the binding material gives smooth surface. Charcoal powder with rice husk and saw dust gives smooth surface with cow dung and roughness with wheat flour paste. Therefore, as binding material cow dung found to be more suitable than wheat flour paste. Moreover, agarbatties with wheat flour paste get attacked by saprophytic fungi in storage.

            Longevity of burning is also recorded. It is observed that all combinations of burning material with all combinations of binding material show maximum burning longevity with sandal wood powder. Charcoal powder if combined with saw dust show more longevity. Charcoal powder singly is somewhat inferior with respect to burning longevity.

            Dhoop, dhoop + ajwain seeds and sandal wood powder give good smell with almost all combinations of burning  and binding material. Wheat flour paste affects the smell. Rice husk as burning material along with cow dung as binding material gives objectionable smell. Rose water as fragrance is inferior as the smell of Agarbattis is not good.

            Overall it is observed that among all the burning material, binding material and fragrance are studied, charcoal powder with saw dust is more suitable for burning longevity. Dhoop, dhoop+ ajwain seeds and sandal wood powder have good smell and cow dung is suitable to give smooth surface to agarbatties. Saw dust provides good porosity and looseness to agarbatties.
