There are two main types of ecosystems: terrestrial and aquatic. Terrestrial ecosystems include grasslands like savannas and prairies, forests which are divided into tropical rainforests, temperate rainforests, and taigas, deserts, and tundras. Aquatic ecosystems consist of marine ecosystems found in oceans, coral reefs, seas, and estuaries which are salty and freshwater ecosystems including lakes, ponds, rivers, and wetlands which have lower salt concentrations. Ecosystems are classified based on the living and nonliving interactions that occur within them and whether they are found on land or in water.

Concepts of trophic structure, food chain and food web. energy flow in ecosys...
Trophic structure refers to the pattern of energy and matter transfer between trophic levels in an ecosystem. A trophic level is a position in a food chain that an organism occupies based on its source of food. Primary producers, such as plants, occupy the first trophic level. Herbivores that eat plants are secondary consumers at the second trophic level. Carnivores that eat herbivores are tertiary consumers at the third trophic level. Decomposers that break down dead organisms are at the fourth trophic level. Energy and biomass decrease at each higher trophic level due to inefficiencies in energy transfer between levels. Food chains and food webs illustrate the trophic structure and allow energy to
8[1].1 biotic & abiotic components
This document discusses the components and interactions within ecosystems. It defines an ecosystem and identifies its two main components as abiotic (non-living) factors like climate and biotic (living) organisms. The biotic components are classified into producers, consumers, and decomposers. Their interactions through food chains, food webs, and symbiosis are explained. Competition between organisms and predator-prey relationships are also covered.
edaphic factors
Soil is formed by the weathering of parent rocks. It consists of mineral particles, organic matter, water, and air. The vertical layers of a soil are called a soil profile, which typically consists of six horizons - O, A, B, C, D, and R. Soil texture refers to the proportions of particles like sand, silt, and clay. Other important soil properties include density, porosity, permeability, temperature, water, chemical composition, and organisms. Soil organisms play an important role in processes like nitrogen fixation, decomposition, and soil mixing.

Laws of Thermodynamics in an Ecosystem
There are two laws of thermodynamics. On the other hand in our universe sun is the source of energy. Green plants are the only producer. Plants make their own food by sunlight with the help of water and carbon dioxide. Other animals get energy by consuming green plants, plant products and other animals. Hence the energy is cycle. So the ecosystem proves the two laws of thermodynamics.
Aquatic environment
An aquatic ecosystem is a community of organisms that live in bodies of water. There are two main types: marine ecosystems, which cover most of the Earth's surface, and freshwater ecosystems, which include lakes, rivers, and wetlands. Freshwater ecosystems can be lentic (still water) or lotic (flowing water). Lentic systems have littoral, photic, and aphotic zones, while lotic systems have zones determined by flow speed. Water pollution is a major threat and can kill organisms by reducing oxygen or increasing nutrients.
Ecology Levels of Organization
Ecology is defined as the study of interactions between organisms and between organisms and their environment. It examines these relationships across a hierarchy of scales ranging from species to the biosphere. Species interact as populations within communities that make up ecosystems, which combine to form biomes and ultimately the biosphere - all living things on Earth and their interactions with each other and the physical world.
Biodiversity ist lecture
This document discusses biodiversity, including its definition, importance, levels, threats, and patterns. It defines biodiversity as the variety of organisms within an ecosystem and notes it involves more than just species counts. It outlines how biodiversity benefits the global economy through agriculture, recreation, and trade. It then describes the three main levels of biodiversity - genetic, species, and ecosystem diversity. The document also discusses threats like habitat destruction, overexploitation, pollution, and climate change. It notes patterns involving vulnerable species groups like rare, long-lived, and keystone species. Finally, it contrasts conservation with preservation approaches to biodiversity management.
Community ecology
Community ecology is the study of interactions between populations of different species within a defined area. A community consists of producers, consumers, and decomposers at various trophic levels. Species diversity and dominance characterize communities. Dominant species exert more influence over energy flow and physical structure. Communities develop through successional changes over time, eventually reaching a climax community. Stratification describes the vertical layering of communities according to plant height, while horizontal stratification refers to dispersion patterns of individuals across an area. Ecotones are transition zones between two communities that contain characteristics of both.
Biotic components
The document outlines the biotic components of an ecosystem, categorizing them as producers, consumers, and decomposers. Producers are autotrophic organisms like plants that use photosynthesis to produce food from inorganic substances. Consumers include heterotrophic organisms like animals that obtain energy and nutrients by consuming producers and other organisms. Consumers are divided into primary, secondary, and tertiary consumers based on trophic level. Decomposers such as fungi and bacteria break down dead organic matter from producers and consumers, recycling nutrients back into the ecosystem.
Biotic Factors in an Ecosystem
Biotic factors are living components of an ecosystem that are categorized as producers, consumers, or decomposers. Producers, such as plants and algae, harness energy from sunlight or chemicals through photosynthesis to produce their own food. Consumers, including herbivores, carnivores and omnivores, obtain energy by eating other organisms. Decomposers like bacteria and fungi break down dead organic matter and waste into simpler substances, recycling nutrients in the ecosystem.
Ecological sampling
This document discusses various methods for sampling plant communities. It describes transect and quadrat sampling methods. Transects involve recording plant species along a line or measuring their vertical distribution by digging trenches. Quadrats involve placing a grid and counting organisms within each square. The document also discusses measuring density, coverage, frequency, biomass, and diversity of plant species within samples. It provides formulas for calculating these metrics and comparing values between species.

PRACTICAL 3 QUADRANT METHOD
1) The document describes the quadrat sampling method, a technique used to estimate population sizes of organisms that do not move around much like plants, shells, and some beetles.
2) The method involves constructing quadrats (square frames) of a fixed size within the study area and randomly selecting some number of quadrats. All organisms of the target species within each quadrat are then counted.
3) The average number of each species per quadrat is calculated and multiplied by the total number of quadrats to estimate the overall population size for that species within the entire area.
Terrestrial and Aquatic Ecosystem, Biomes and distribution
These slides cover the types of the terrestrial and aquatic ecosystems. Briefly states the basic definition, the distinguish factors moreover the flora and fauna found at these places.
Population Ecology
Population ecology examines populations as units of study. A population has characteristics like density, size, age structure, and dispersion. The four basic population parameters that affect density are natality, mortality, immigration, and emigration. Techniques to estimate population density include using quadrats, capture-recapture methods, and calculating relative density with tools like traps or roadside counts. Life tables can describe mortality schedules by tracking age-specific cohort survival. Population growth rates depend on birth and death rates, and can be modeled exponentially or logistically depending on environmental constraints.

The document also outlines the different zones of the oceans from the epipelagic zone at the surface to the deepest hadalpelagic zone, and notes some characteristic animals found in each zone.
Resource conservation
Resources include anything that can satisfy human needs, including natural resources like water, biotic resources, and land resources. It is important to conserve resources for current and future generations by preventing depletion and ensuring continuous long-term availability. Land resources provide agricultural land, water, and mines. Land is used for residential, commercial, industrial, and transportation purposes, but degradation through overuse of land and deforestation is a problem. Water resources are sources of water for agriculture, industry, households, and the environment, so water conservation through efficient use and management is important. Biotic resources include animals, plants, forests, and microorganisms, and various measures are taken to conserve species and their habitats.

Activities Affected by Natural Objects in the Sky.pptx
The document discusses various activities that are affected by natural objects in the sky such as the sun, moon, stars, and clouds. The sun affects drying crops, work schedules, school schedules, and outdoor activities like going to the beach or park. The moon and stars influence nighttime activities like fishing, stargazing, and family movie nights as well as sleeping schedules. Clouds can impact outdoor activities like bike riding.
A_Prediction_Lesson.pptx
This document discusses using art to practice making predictions by looking at pictures and thinking about what is happening and what may happen next based on clues. Students are asked to make predictions about what is occurring and will occur next after viewing several paintings. The document then prompts predicting outcomes from short stories by having students closely examine details and use prior knowledge.
Intro to Equations and Expressions.ppt
This document defines key terms related to expressions and equations. It explains that expressions use words like sum and number, while equations use equal signs and are written as sentences. Examples are given of expressions like x + 6 and equations like x + 6 = 10. Terms, coefficients, constants, and like terms are defined for expressions. Inverse operations are defined for solving equations. Methods are provided for translating verbal phrases and sentences into algebraic expressions and equations.
subjectverbagreement.ppt
Subject-verb agreement refers to making the subject and verb match in number. To make a noun plural, add -s. To make a verb plural, remove -s. There are also irregular verbs like "be", "have", and "do" that have unique plural forms. As a general tip, if the subject doesn't end in -s, the verb will, and if the subject does end in -s, the verb won't. Multiple subjects joined by "and" take a plural verb.
Abbreviations.pptx
Abbreviations are shortened forms of words that often use periods after the letters. Common abbreviations include days of the week like Sun. and months of the year such as Dec. Titles and names can also be abbreviated, for example Prof. for Professor and Ms. for Miss.
syllables-fun-activities-games_55019.pptx
This document discusses how to count syllables in words. A syllable is a single unit of sound within a word. Words can have different numbers of syllables, such as "tie" having one syllable and "alphabet" having three syllables. The document recommends clapping out the syllables in words to count them, such as clapping three times for "umbrella" and five times for "I like to eat cheese." Counting syllables helps determine the rhythm or "beats" in words.
13534.ppt
This document defines and explains the key terms used to describe the different parts of a circle:
- The circumference is the distance around the outside of the circle. The diameter is the distance from one side to the other passing through the center.
- The radius is the line connecting the center of the circle to the circumference. A chord is a line touching the circumference at two points.
- A sector is the part of a circle between two radii. An arc is the part of the circumference at the edge of a sector. A segment is the part between a chord and an arc.
- A tangent is a straight line touching the circle at just one point. The document includes diagrams labeling these different parts
Natural Objects in the Sky.pptx
Daytime objects in the sky include the sun, which Earth revolves around, clouds which are important for weather, and rainbows which are formed when sunlight hits raindrops and splits into colors. Nighttime objects are the moon, which orbits Earth, stars which are bright balls of gas that give their own light, and planets.
Musical Form.pptx
Musical form refers to the structure or organization of a musical composition. There are several common forms, including binary form consisting of two contrasting sections (AB), ternary form with three sections (ABA) where the first and third sections are the same, and rondo form with a recurring theme or refrain alternating with different episodes (ABACA). The form helps composers organize their pieces and involves different melodic phrases, sections, and the repetition or contrast of musical ideas.
arithmetic sequences explicit.ppt
The document provides information about arithmetic sequences including defining the first term (a), common difference (d), and the explicit formula to find any term (an) in an arithmetic sequence. It gives examples of finding specific terms and writing recursive and explicit rules for arithmetic sequences.
syllables-fun-activities-games_55019.pptx
This document discusses how to count syllables in words. A syllable is a single unit of sound within a word. Words can have different numbers of syllables, such as "tie" having one syllable and "alphabet" having three syllables. The document recommends clapping out the syllables in words to count them, such as clapping three times for "umbrella" and five times for "I like to eat cheese." Counting syllables is done by hearing the separate sounds or "beats" in each word, rather than individual letters or sounds.
Euphemism.pptx
Euphemism is a polite expression used in place of a rude, harsh, or embarrassing statement to avoid offending or humiliating someone. Euphemisms are made up of three Greek morphemes meaning "good voice act/result" and are used to soften expressions like "died" to "passed away" or describe someone as attending "remedial classes" rather than being "corrective". Common euphemisms include replacing "garbage man" with "sanitation engineer", calling the elderly "senior citizens" rather than "old people", and referring to pregnancy as being "in the family way".
Congruent Figures.pptx
Two figures are congruent when they have the same size and shape. Two triangles are congruent when their corresponding angles and sides are equal in measure. The document provides examples of identifying congruent triangles by showing that their corresponding angles and sides are equal.
Safety Measures for Different Weather Conditions.pptx
On sunny days, people are at risk of headaches, sunburn, dehydration, and heatstroke. To stay safe in the heat, one should apply sunscreen, stay in the shade, wear sunglasses or a hat, drink plenty of water, and wipe sweat off the body. During rainy weather, people may get coughs or colds, so it's important to wear boots, sweaters, jackets, and use an umbrella, and eat warm food.
Becoming Compassionate.pptx
This document discusses how to become compassionate by showing empathy and helping those who are suffering through acts of mercy, such as feeding the hungry, sheltering the homeless, and visiting the sick. It encourages showing compassion when encountering victims of calamity by giving comfort and aid. Several examples are provided of compassionate acts like donating to charities, volunteering, and caring for family members.
force, motion, and energy.pptx
Force can cause changes in the motion, shape, and size of objects. It can make stationary objects begin moving, slow or accelerate moving objects, and change the direction of moving objects. Friction is a type of force that occurs when two surfaces rub against each other. Applying more force to an object generally causes greater changes, such as compressing an object more if a stronger force is exerted.
Nets of Solid Figures.pptx
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
affixes-clt-communicative-language-teaching-resources-read_49190.ppt
This document discusses affixes, including prefixes and suffixes. It provides examples of common prefixes like anti-, de-, dis-, en-, and in- and their meanings. Some common suffixes are -able, -al, -ed, -en, -er, -est, -ful, -ic, -ing, -(t)ion, -(i)ty, -(t)ive, and -ly. Affixes are added to root words to modify or change their meaning. Knowing common prefixes and suffixes can help the reader understand new words and sounds more educated.
assonance_and_consonance_01.pptx
This document defines and provides examples of consonance, assonance, and alliteration. Consonance is the repetition of consonant sounds anywhere in a word. Assonance is the repetition of vowel sounds anywhere in a word. Alliteration is the repetition of any sounds at the beginning of words. The document compares and contrasts these three literary devices used to repeat sounds in language.
Geometry, Patterns, and Algebra.pptx
Polygons are plane figures formed by three or more line segments called sides that meet at points called vertices. A regular polygon has all interior angles that are congruent, while an irregular polygon does not have congruent interior angles. Regular polygons include triangles, squares, pentagons and other figures with five or more sides where all interior angles are equal.

Types of Ecosystems.pptx
- 2. Ecosystem โ a community of interacting organisms and their environment. - classified as terrestrial or aquatic based on where they are found.
- 3. Terrestrial Ecosystems โ consists of the interactions between plants, animals, and nonliving things that occur on land.
- 4. โข Grasslands โ an open area of flat land that mainly comprises of grasses with a few trees and shrubs. Two kinds of grasslands: โ Savanna โhas a seasonally dry climate and thus can support only a few trees. โ Prairie โ has a temperate climate. It does not have shrubs or trees.
- 6. โข Forests โ usually a small space that is filled with different types of plants because it receives plenty of rain. Three Kinds of Forests: โ Tropical rainforest โ located in tropical regions, which have high chance of rain. โ Temperate rainforest โ has cold winters and warm summers, with enough rainfall all year- round. โ Taiga โ a type of forest that is located in the northern regions of the world, thus the weather is very cold for almost half of the year.
- 7. Tropical rainforest Temperate rainforest Taiga or Boreal Forest
- 8. โข Deserts โ has extremely high temperatures and a dry climate. Rainfall is rare, thus, there is little water to be found.
- 9. โข Tundras โ a frozen land that is covered in snow for most of the year. - has no trees, and only a few kinds of plants grow.
- 10. Aquatic Ecosystems โ consists of interactions of living and nonliving things in any water-based environment. Two kinds: marine freshwater - The difference between these two is the concentration of salt in water (called salinity) as well as the depth of the water and the amount of available sunlight.
- 11. o Marine ecosystems or salt water - An aquatic ecosystem that has a high concentration of salt. Examples: oceans coral reefs seas estuaries
- 12. โข Oceans โ covers most of Earthโs surface. Three zones or layers (based on sunlight) 1. euphotic zone โ the surface, has an average depth of 40 m. and receives the most sunlight. 2. disphotic zone โ the middle layer, receives some sunlight but not enough for plants to survive 3. aphotic zone โ deep below layer, completely dark and very cold.
- 14. โข Estuaries โ a place where a river meets the sea. It is an area where the saltwater of the sea mixes with freshwater.
- 15. โข Coral Reefs โ an underwater ecosystem that is held together by the calcium carbonate structures that are given off by organisms such as algae with calcium carbonate.
- 16. โข Coasts โ also called seashore, is formed by the land on the shore and the sea next to it.
- 17. o Freshwater Ecosystem - is shallow and has a low concentration of salt compared with a marine ecosystem. Examples: pools rivers lakes streams ponds wetlands
- 18. โข Ponds โ a small, shallow body of water that is usually smaller than a lake.
- 19. Rivers and streams โ are freshwater ecosystems that have flowing water.
- 20. Underground river in Palawan
- 21. โข Wetlands โ is also called a swamp.
