The process of nutrition allows living organisms to obtain food and use it for growth, metabolism, and repair. Both plants and animals require nutrition throughout their lives. Plants can produce their own food through photosynthesis and are autotrophic. They require macronutrients like carbon, hydrogen, and nitrogen, as well as micronutrients like iron and copper. Nitrogen is a vital substance that is a major component of proteins, hormones, chlorophyll, vitamins, and enzymes essential for plant life. Nitrogen metabolism also plays a major role in stem and leaf growth.

Essential plant nutrients by dilip kumar chandra
This document discusses essential plant nutrients and how they are classified. It outlines that 17 elements are considered essential for plant growth according to specific criteria. These elements can be classified based on their concentration in plants as either macronutrients, which are needed in larger quantities, or micronutrients, which are needed in smaller amounts. They can also be classified into four groups based on their biochemical behavior and physiological functions in plants. The four groups include elements that are major constituents of organic materials, involved in biochemical reactions, present in free ionic states or adsorbed to organic anions, or predominantly present as chelates.
Lesson 3 nutrition in living organisms
Nutrients like carbohydrates, fats, proteins, vitamins, and minerals provide living organisms with the materials needed to build their bodies, grow, repair damage, and power life processes. Nitrogen is essential for organisms but it exists primarily as unusable atmospheric N2; biological fixation by rhizobium bacteria in legume roots and other soil microbes, as well as atmospheric fixation from lightning, make nitrogen biologically available for use by plants and animals.
The chemical industry
The document discusses South Africa's chemical industry and fertilizer production. It notes that South Africa's chemical industry grew due to the mining industry's need for explosives.

photosynthesis and chemosynthesis
Autotrophs can produce their own food through either photosynthesis or chemosynthesis. Photosynthesis uses sunlight as an energy source and occurs in plants, algae, and some bacteria containing chlorophyll. Chemosynthesis uses inorganic molecules from ocean vents as an energy source for bacteria. Heterotrophs cannot produce their own food and must obtain energy by consuming other organisms, breaking down food through cellular respiration.
Nutrition in Plants
Plants obtain nutrition through various modes including autotrophic, heterotrophic, and saprotrophic nutrition. Autotrophic nutrition, which is found in green plants, involves plants making their own food through photosynthesis. During photosynthesis, green plants such as leaves use carbon dioxide, water, and sunlight to produce carbohydrates and release oxygen. Some non-green plants rely on heterotrophic nutrition and obtain nutrients from other living organisms. Saprotrophic plants get nutrients from decaying organic matter. Symbiotic relationships also provide nutrition, such as rhizobium bacteria living in root nodules of legumes that provide nitrogen to the plant in exchange for shelter and food.

It explains that plants obtain nutrients through autotrophic nutrition, by producing their own food through photosynthesis using water, carbon dioxide, sunlight, and chlorophyll. Photosynthesis is defined as the process by which plants produce food using these components. The key stages of photosynthesis are explained, including how sunlight is trapped by chlorophyll and how carbon dioxide and water are converted into food in the leaves.
Introduction to principles of plant physiology
Plant physiology is the study of how plants function at the cellular and biochemical levels and respond to their environment. It examines plant metabolism, growth, transport, water relations, and responses to stresses and environmental factors. Plant physiology relies on biology, chemistry, and physics and serves as the foundation for advances in agriculture, forestry, pharmacology, and other fields. Understanding plant physiology allows for improvements like increasing photosynthetic efficiency, producing disease-resistant crops through tissue culture, and optimizing plant nutrition and growth through techniques like pruning, irrigation, and growth regulators.

Plant physiology
Nutrients provide organisms with materials to build their bodies, grow, repair damage, and provide energy. Photosynthesis uses light energy from the sun to convert carbon dioxide and water into oxygen and carbohydrates like glucose, providing a key source of food for plants and energy for life. There are two phases - the light reaction uses solar energy to produce ATP and NADPH while splitting water, and the dark reaction uses these products to reduce carbon dioxide into carbohydrates through the Calvin cycle.
Bioactive compounds of citrus as health promoters
This document summarizes the key bioactive compounds found in citrus fruits, with a focus on ascorbic acid (vitamin C). It discusses the chemistry and biological properties of ascorbic acid, noting that citrus fruits are particularly rich in vitamin C. The content of ascorbic acid varies between citrus species and cultivars, with oranges and clementines generally having the highest amounts. The rind contains more vitamin C than the pulp. Ascorbic acid levels also depend on fruit development and rootstock selection. Other bioactive compounds in citrus like carotenoids and flavonoids are briefly mentioned.
Marine Ecosystem
This document provides an overview of marine and freshwater ecosystems. It discusses key abiotic factors such as temperature and salinity. It also describes different zones within marine ecosystems like the oceanic zone. Freshwater ecosystems are divided into lentic, lotic, and wetlands. Important biotic components of ecosystems include producers like algae, consumers such as animals, and decomposers such as bacteria and fungi. Autotrophs fix carbon to produce organic compounds while heterotrophs rely on autotrophs for food.
Nutrition
This document discusses different modes of nutrition in living organisms. It describes autotrophic nutrition, which occurs in organisms like plants that can synthesize their own food through photosynthesis or chemosynthesis. It also describes heterotrophic nutrition, where organisms obtain organic carbon from other living things. Heterotrophic nutrition includes saprophytic, parasitic, and holozoic (animal) modes. Photosynthesis uses carbon dioxide, water, and sunlight to produce oxygen and energy-rich organic compounds like carbohydrates. It takes place in chloroplasts in plant cells.
Role of microrganisms in aquaculture. c
1. Microorganisms play several key roles in aquaculture including productivity, nutrient cycling, decomposition, mineralization, and waste water treatment.
2. Bacteria, fungi, viruses, protozoa, phytoplankton, and zooplankton are important microorganisms that contribute to these processes. They drive processes like carbon, nitrogen, phosphorus, and sulfur cycling that make nutrients available to aquatic organisms.
3. Microorganisms decompose organic matter into inorganic nutrients and are also involved in waste water treatment through biodegradation and bioremediation processes that break down pollutants. Their roles are vital for a balanced and productive aquaculture ecosystem.
Essential element
The document discusses mineral nutrition in plants. It states that plants need 17 essential elements for growth and completion of their lifecycle, including carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, and others. These elements are absorbed from the soil mainly in ionic form. The elements are classified based on amount needed, mobility, chemical nature, and function. Nitrogen deficiency results in stunted growth and pale yellow leaves starting at tips due to reduced chlorophyll production and translocation of nitrogen to younger tissues.

Autotrophic and heterotrophic nutrition are the two types of nutrition. Autotrophic nutrition is the process by which autotrophs like plants produce their own food by taking in carbon dioxide and water and converting them into carbohydrates through photosynthesis using chlorophyll in the presence of sunlight. Heterotrophic nutrition involves organisms like animals depending on other organisms for food. Autotrophs include plants while heterotrophs include parasites, saprophytes, and humans.
Micro organisms in the ecosystem
This document discusses the roles of micro-organisms in ecosystems. It describes how viruses, bacteria, algae, fungi, and protists help control nutrient cycling and biodiversity. Bacteria are important for decomposition, recycling nitrogen, and producing nutrients for plants. Fungi decompose dead organic matter. The document also discusses symbiotic relationships between organisms, including mutualism, parasitism, and commensalism. An example of mutualism is nitrogen-fixing bacteria providing nitrates to plants in exchange for food.
Lesson 1 nutrition in plants
Nutrition in plants can occur through two main modes: autotrophic and heterotrophic nutrition. Autotrophic nutrition involves plants producing their own food through the process of photosynthesis using carbon dioxide, water and sunlight. Heterotrophic nutrition involves plants that cannot produce their own food and instead rely on other organisms for nutrition, such as parasitic plants that derive nutrients from a host plant, or saprotrophic fungi that break down dead and decaying matter.
Nitrogen cycle
1) Nitrogen is essential for life but is inert in the atmosphere. Microorganisms play a key role in converting atmospheric nitrogen into organic nitrogen compounds through processes like nitrogen fixation.
2) The nitrogen cycle describes how nitrogen is transformed between its various chemical forms through biological and environmental processes. It involves nitrogen fixation, ammonification, nitrification, and denitrification.
3) Key microorganisms are involved in nitrogen fixation (converting N2 to organic nitrogen), ammonification (production of ammonia from organic matter), nitrification (conversion of ammonia to nitrites and nitrates), and denitrification (reduction of nitrates back to nitrogen gas). This allows nitrogen to be recycled for use by plants

bio-indicators. The present study is focused on the effective use of L. rohita, an economically significant carp as a
bio-indicator of zinc pollution through its several physiological, histopathological biomarkers. Primarily, acute toxicity
test is performed in which the carp fingerlings are exposed to different concentrations (10, 20, 40, 80, 160, 320 ppm) of
zinc sulphate. 96 hour LC50 value is determined to be 100 ppm. It is taken as lethal concentration and the fishes are
exposed to it for a period of 96 hours during which wide range of behavioural abnormalities are evidenced like general
hyperactivity, surfacing activity, hyper-opercular activity, and erratic swimming pattern. It is followed by loss of balance
and convolutions. One fifth of the lethal concentration is taken (i.e., 10 ppm) as sub-lethal concentration and fishes are
exposed to it for a period of 15 days during which growth, behaviour, oxygen consumption, histopathology, hematology
and genotoxicity are studied. Negative growth performance is observed with insignificant length increment up to 0.24 %
and significant weight reduction up to -2.38 %. Wide range of behavioural abnormalities are evidenced which includes,
erratic swimming, hyperactivity, surfacing activity and depression in appetite. Besides, general body discolouration and
haemorrhage are observed as well. Rate of oxygen consumption showed a time dependant decrease which ranged up to
-49.10%. Gills of the fishes are shown to have conspicuous histopathological alterations like lamellar necrosis, lamellar
fusion, lamellar erosion, epithelial lifting and epithelial swelling. Key-words- Bioindicator, L. rohita, Zinc sulphate, Growth, Behaviour, Oxygen Consumption, HistopathologyNutrition in living organisms

North Korea experienced a food crisis after losing support from the Soviet Union, which had previously provided chemicals and petroleum needed for agriculture. Without these imports, North Korea could no longer produce sufficient fertilizer, which is essential for supplying nitrogen and other nutrients to crops. Nitrogen is the nutrient most often limiting for plant growth, and industrial fertilizer production requires significant energy from petroleum. As a result, North Korea's farming system failed due to the lack of fertilizer inputs, leading the country to experience widespread starvation.

NUTRITION IN PLANTS
Nutrition in plants is very important for plant life. Plants obtain nutrients through autotrophic nutrition, where they produce their own food through photosynthesis using water, carbon dioxide, sunlight, and chlorophyll. Photosynthesis is the process where plants use these components to produce carbohydrates, which provide the plant with nutrients and energy. Plants take in water and dissolved mineral salts from the soil through their roots, which travel up the xylem vessels to the leaves. In the leaves, the mixture combines with carbon dioxide through photosynthesis to produce the plant's food.

Growth & nutrition of bacteria
This document discusses the growth and nutrition requirements of bacteria. It explains that bacteria require major elements like carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur to support growth. Trace elements and vitamins are also needed. The document outlines different types of bacteria based on their carbon and energy sources, including photoautotrophs, chemoautotrophs, photoheterotrophs, and chemoheterotrophs. It also discusses various types of culture media used to grow bacteria, such as simple, complex, synthetic, enriched, selective, indicator, differential, sugar, transport, and anaerobic media.
NUTRITION FOR MICROBIAL GROWTH
Microorganisms require nutrients for growth and metabolism. There are two categories of essential nutrients: macro-nutrients which are needed in large amounts to maintain cell structure and metabolism, and micro-nutrients which are needed in trace amounts to help enzyme function and maintain protein structure. Microorganisms obtain carbon, nitrogen, and other macro-nutrients from both inorganic and organic sources, while micro-nutrients like metals serve as catalysts in enzymes. Microorganisms are also classified based on their energy and electron sources as phototrophs or chemotrophs, and lithotrophs or organotrophs.
Nutrition in plant
Plants obtain nutrients through photosynthesis, a process where they convert sunlight, water and carbon dioxide into oxygen and energy in the form of glucose. There are two modes of nutrition - autotrophic organisms like plants can produce their own food through photosynthesis, while heterotrophic organisms like animals must obtain food from other sources. Photosynthesis takes place in the leaves of plants, which contain chlorophyll and open pores called stomata that take in carbon dioxide from the air.
Lect. 3 (microbial nutrition and cultivation)
Microbial growth conditions depend on various nutrients and environmental factors. Microorganisms require macronutrients like carbon, nitrogen, phosphorus and micronutrients in small amounts. They also need growth factors like vitamins and amino acids. Temperature, pH, and oxygen levels influence microbial growth. Pure cultures can be isolated using techniques like streak plating that allow single microbial cells to grow into separate colonies.

Mineral nutrients are essential elements obtained from the soil by plant roots and utilized for metabolism, growth, and development. These elements are absorbed, translocated throughout the plant, and participate in numerous biological functions with the help of mycorrhizal fungi and nitrogen-fixing bacteria. The study of how plants obtain and use these mineral nutrients is called mineral nutrition, which is important for agriculture and environmental protection as crop yields depend on fertilization. There are 17 essential mineral elements for plants, categorized as major/macronutrients which are required in large amounts or minor/micronutrients which are required in trace amounts. These elements have various functions as cell constituents, in osmotic pressure regulation, and catalytic/ant
2.1 trophic levels
This document discusses biotic and abiotic factors in ecosystems and trophic levels. It defines biotic factors as living components like plants, animals, bacteria and fungi. Abiotic factors are non-living like temperature, water, soil and sunlight. There are trophic levels in a food chain including primary producers, primary consumers, secondary consumers, tertiary consumers and apex predators. Energy flows through the food chain from producers to consumers at different trophic levels, and decomposers break down waste and make nutrients available again.

Chp # 6 ppt microbio.pptx
This document discusses the nutritional requirements of bacteria, including their need for sources of energy, electrons, carbon, nitrogen, oxygen, sulfur, phosphorus, metals, vitamins, and water. Bacteria can utilize chemical compounds or light as an energy source, and inorganic or organic compounds as electron donors and carbon sources. They also require nitrogen, usually sourced from the atmosphere, inorganic compounds, or organic compounds. Additionally, bacteria need small amounts of various other elements like oxygen, sulfur, phosphorus, and metals to carry out metabolic functions and build cell components. Some bacteria can synthesize required vitamins while others require them to be supplied. All bacteria ultimately require water for nutrient uptake and metabolic reactions.
Daksh shandilya ppt our environment class 6 dav
This document discusses the biotic and abiotic components of the environment. The biotic environment includes all living organisms like plants, animals, and microorganisms. Plants produce their own food through photosynthesis while animals obtain food by eating plants or other animals. Decomposers break down dead organic matter and return nutrients to the soil. The abiotic environment refers to non-living factors like air, water, soil, light and temperature, which affect living organisms. These biotic and abiotic components interact with each other through food chains, nutrient cycles and other ecological processes.

Ionization energy
- Ionization energy is the amount of energy required to remove an electron from an atom. The first ionization energy is the amount required to remove the outermost electron.
- More energy is required to remove the second electron compared to the first, and even more for the third electron.
- Ionization energy decreases down a group as the atomic number increases since electrons are farther from the nucleus and more shielded.
- There is a general trend of increasing ionization energy when moving left to right across a period as protons are added making electrons more tightly bound.
I.e and electroneg
1. Ionization energy is the amount of energy required to remove an electron from an atom or ion. The first ionization energy is the amount required to remove the outermost electron from a neutral atom.
2. Ionization energies generally increase as each successive electron is removed from an atom. They decrease down a group and increase across a period on the periodic table. Noble gases have the highest ionization energies due to their stable electron configuration.
3. Electronegativity is a measure of how strongly an element attracts electrons in a bond. It shows similar trends to ionization energy, decreasing down groups and increasing across periods. Electronegativity values are used to determine if molecules are polar or non

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
