1) The document discusses key aspects of ecosystems and the environment, including biotic and abiotic factors, producers, consumers, decomposers, and trophic levels.
2) It explains how human activities impact the environment through waste production and chemical usage, and how non-biodegradable materials can accumulate up the food chain.
3) The document also covers the roles of plants and photosynthesis in energy flow, and environmental issues like ozone layer depletion and waste disposal.
Ecosystem
The movement of energy and matter in an ecosystem starts with photosynthetic organisms like plants getting energy from the sun. Plants process this energy along with water and carbon dioxide to produce glucose. Organisms that feed on producers are consumers or heterotrophs, while decomposers break down dead organic material and return nutrients to the soil or water in a cycle. Ecosystems have multiple trophic levels with producers on the first level, herbivores on the second, and carnivores and omnivores on third and fourth levels. Scavengers feed on dead organisms while decomposers break them down further.
Abiotic components
Biotic components are living things like plants, animals, and humans that shape ecosystems. They need energy and food - plants produce food through photosynthesis, animals and humans consume other organisms or their byproducts, and decomposers like bacteria and fungi break down dead matter. Abiotic components are non-living environmental factors such as sunlight, soil, water, and air that affect ecosystems. Both biotic and abiotic factors work interdependently to provide a functioning environment for organisms in an ecosystem.
Edu 290 Ecosystem Lesson
An ecosystem is defined as the interaction between living and nonliving things in an environment. Ecosystems exist everywhere and range in size from small backyard gardens to large savannas. All organisms in an ecosystem are interdependent and disruptions can be disastrous, as they upset the natural balance. Foreign invaders can also disrupt ecosystems by competing with native species.
Abiotic and biotic factors
Abiotic factors refer to non-living environmental conditions such as sunlight, temperature, rainfall, and soil composition. Biotic factors refer to living organisms such as plants, animals, and other organisms that inhabit an environment. Examples of biotic factors include grass providing energy for cows and abiotic factors including sunlight affecting whether plants can grow. The document discusses the difference between abiotic and biotic factors and provides homework questions about examples of each, definitions of populations and communities, and whether certain atmospheric gases are abiotic factors.

The document announces a webinar series on sustainability with three upcoming webinars - on April 22nd about biodiversity, April 26th about overfishing, and April 29th about alumni research projects on sustainability. It also lists the contact information for Professor Jens Gebauer who studies sustainable agricultural production systems and indigenous fruit trees in Africa.
Abiotic factors
Abiotic factors are non-living elements of an ecosystem including soil, water, temperature, air, and light. Soil provides nourishment to plants while air and water are essential for respiration and photosynthesis in organisms. Proper levels of these abiotic resources are necessary for organisms' metabolic activities and survival within an ecosystem.

An ecosystem consists of all the living and nonliving components in an environment and the interactions between them. It includes biotic factors like producers, consumers, and decomposers as well as abiotic factors such as water, sunlight, and temperature. Producers like plants obtain energy through photosynthesis while consumers obtain energy by consuming other organisms. Decomposers play an important role by breaking down dead organic matter and recycling nutrients.
Ecosystems, Lesson 2
An ecosystem is defined by the interaction between living and non-living factors. Living components are called biotic factors, while non-living components are called abiotic factors. Abiotic factors like sunlight, water, air, and soil affect biotic parts of an ecosystem by providing warmth, energy for photosynthesis, oxygen, nutrients, and habitats.
Discovery Day Unks
This document summarizes Ryan Unks' research on linking pastoralism and landscape ecology in Laikipia County, Kenya. It discusses how pastoralist herding practices have changed over time due to loss of land and influences of the market. Vegetation across the landscape has also changed, with increases in unpalatable species and decreases in species important for pastoralists. The research aims to understand how social and institutional factors influence grazing practices and spatial relationships between plant communities and grazing. The goal is to explore implications of interrelated social and ecological changes for livelihoods and natural resource management. Methods include interviews, surveys, satellite image analysis, and plant community analysis.
Chapter2
This document provides an overview of key concepts in ecology, including:
- Ecosystems are made up of biotic (living) and abiotic (non-living) factors that interact in complex ways. Nutrients cycle through ecosystems via producers, consumers, and decomposers.
- Ecological pyramids illustrate the transfer of energy and biomass between trophic levels in an ecosystem, with higher levels containing fewer and smaller organisms due to energy losses between levels.
- Symbiotic relationships between species include mutualism, commensalism, and parasitism, with examples like cleaner fish and their client fish demonstrating mutualism.
Ecology and ecosystem
The document discusses various topics in ecology including ecosystems, ecological succession, food chains, food webs, and different types of ecosystems such as forests, grasslands, deserts, and aquatic ecosystems. It provides information on key concepts such as how ecosystems are defined, the process of ecological succession, how energy passes between producers and consumers in food chains and webs, and examples of different forest, grassland, desert and aquatic ecosystems. In the end, it emphasizes man's responsibility to conserve and protect ecosystems.
Ecosystem Presentation Amity International Business School
An ecosystem is a biological community of interacting organisms and their physical environment. It includes biotic components such as plants, animals, fungi and microbes, as well as abiotic components like air, water, and mineral soil. Organisms within an ecosystem are organized into populations, communities, and food webs. Ecosystems can vary depending on factors like water, sunlight, and soil, and they can change due to natural causes or human activities such as pollution, construction, and overpopulation. Humans can help prevent ecosystem changes by wisely using resources, controlling pollution through laws, cleaning up litter, and keeping water sources clean.
Ecosystems - Natural Science
This document provides information about ecosystems and environmental concepts. It defines key terms like species, population, community, ecosystem, biosphere. It explains that an ecosystem includes the living community and surrounding non-living environment. Different types of ecosystems are described like terrestrial and aquatic. Relationships between living things in an ecosystem like feeding, competition and cooperation are outlined. The document also discusses how humans alter ecosystems directly through activities like logging and fishing or indirectly through pollution and desertification.
Ecology Lec 07 2016
This document defines key concepts in ecosystem ecology. It explains that an ecosystem is composed of biotic (living) and abiotic (non-living) factors that interact as an integrated system. The main components of an ecosystem are the flow of energy from the sun through producers, the cycling of materials between organisms and their environment, and the interactions between organisms, including producers, primary consumers, secondary consumers, and decomposers in the food web.
Es 4207 pollution biology
This course covers concepts of pollution biology including pollution versus resources, material cycling, tolerance ranges, and carrying capacity. It will examine the responses of plants and animals to air pollution, including using plants to monitor and control air pollution. Topics will include the most common environmental pollutants, their effects on organisms from individual to ecosystem levels, and introduction, dispersion, uptake, and excretion of pollutants. The course focuses on disturbances to healthy ecosystems caused by human-introduced pollutants and alterations to ecosystem interactions.
AP Biology energy and matter transfer through ecosystems
Energy enters ecosystems through photosynthesis, where autotrophs like plants convert sunlight into chemical energy stored in organic compounds. Approximately 10% of this primary productivity is passed to primary consumers at the next trophic level, with smaller percentages passed between higher trophic levels, forming an energy pyramid. Matter cycles through ecosystems as well, with carbon, nitrogen, phosphorus and other elements moving between abiotic and biotic components through natural processes. Human activities like burning fossil fuels and using fertilizers have altered these natural biogeochemical cycles.
Science 7 notes glb lab 04 beneath the surface
This document outlines the key objectives and terms for a lesson on aquatic ecosystems. The objectives include investigating the water, carbon, and nitrogen cycles; differentiating processes within these cycles; recognizing that photosynthesis is part of the carbon dioxide-oxygen cycle; defining biotic and abiotic factors; observing and classifying these factors; defining and describing food chains; comparing terrestrial, freshwater, and marine ecosystems; using food webs and energy pyramids; and relating the role of humans. Key terms defined include ecosystem, biotic factor, abiotic factor, and others related to habitats, populations, and energy transfer such as food chains, webs, and predator-prey relationships.

Ecosystem
An ecosystem is characterized by the interactions between organisms and their nonliving environment. It contains biotic components like living organisms and abiotic components like energy, water, and soil conditions. Within an ecosystem, a community of interacting populations from different species occupies a habitat, which is an area that provides the necessary abiotic components for that community. One of the most important interactions is the flow of energy from producers like plants through food chains and webs to consumers at different trophic levels and ultimately decomposers, which also play an important role in the ecosystem. The abiotic and biotic factors limiting population growth are called limiting factors, and ecological collapse can occur if the balance is greatly disturbed through mass extinction of species in a community.
ECOLOGY, its systems and disturbances
Ecosystems can be classified in various ways based on their size and level of human interference. The biosphere is the largest ecosystem encompassing all others. Ecosystems also exist at the mega, marine, freshwater, semi-terrestrial, terrestrial, urban-industrial, macro, meso, and micro levels. Natural ecosystems are self-regulating without human interference, while artificial ecosystems are man-made like cities and croplands. Disturbances, whether abiotic like tsunamis or biotic like insects, disrupt ecosystems. Succession describes how communities change and recover after disturbances through primary succession in new areas and secondary succession in previously inhabited areas.
The ecosystem 2.5 2.6 2.7
Ecosystems cycle materials and energy through producers, consumers, and decomposers. Photosynthesis and respiration drive carbon and nitrogen cycles. Primary productivity is the gain by producers, while secondary productivity is the gain by consumers. Limiting factors like temperature, resources, and weather influence populations. Succession involves predictable changes in communities over time from pioneer to climax species. Measuring ecosystem changes involves repeated transects, satellite imagery, and environmental impact assessments.
Ess topic 2.1 ecosystem structures
The document defines key terms related to ecosystem structures and population interactions. It distinguishes between biotic (living) and abiotic (non-living) components of ecosystems. Trophic levels including producers, primary consumers, secondary consumers, and decomposers are explained. Pyramids of numbers, biomass and productivity are defined. Species, populations, habitats, niches, communities, and ecosystems are defined using local examples. Population interactions such as mutualism, parasitism, predation, herbivory and competition are described through examples.

1page Define stewardship and define sustainability.
Stewardship of the ecosystem refers to a framework that is action-oriented and that seeks to develop the sustainability of the socio-ecological environment of a planet that is rapidly changing planet. It considers the means through which the resources availed by the environment are managed with the intent of ensuring they are not wasted or exhausted. Sustainability on the other hand refers to the facilitation of current needs by using the environment without jeopardizing future generations’ ability to meet their needs.
Considering the Amazon forest, there are several considerations that can be made in light of the stewardship and sustainable utilization of the resource. To begin with, it is imperative that Amazon resource are conserved by being included as a conservation reserve and marked for protection and sustainability. Additionally, it could be placed under a covenant of conservation. There should also be an inventory of the natural resources in the Amazon including a comprehensive inventory of the biological resources found in the forest and which should be monitored within regular intervals. Additionally, there should be increased research on the identification of maintenance procedures of proper biological and physical processes from the forest. There should also be policies set that determine the sustainable utilization of timber from the Amazon rainforest according to proper standards that will ensure that future generations use of the same is not endangered (Chapin III & Matson, 2011).
The environmental implications that can arise as a result of deforestation of the Amazon forest are innumerable. To begin with animals dependent on the forest would find it difficult to survive and, therefore, may become extinct. This would make them unavailable for future generations. Additionally, deforestation leads to an imbalance between the carbon dioxide: oxygen ratio in the atmosphere. As a result, air pollution will become aggravated.

Changing the Economics of Organic Waste Disposal Using MEF
Concentrated organic waste is a major societal problem. It is a disease vector, a source of groundwater contamination, as well as a source of greenhouse gases. Managed Ecosystem Fermentation (MEF) is a technology that converts this societal problem into an economic resource for the community. MEF is a fermentation process that uses over 3,000 species of microbes simultaneously to produce multiple high-value products used in industry and agriculture. The products include fertilizer, high-protein animal feed, volatile fatty acids, longer chain fatty acids, amino acids, enzymes, etc. The values of these products range from $50 to over $16,000 per ton. MEF is an adaptive system that processes non-homogeneous, non-sterile organic waste/s under non-sterile conditions. It converts the waste into industrial products in 24 hours using a microbial system that has worked for millions of years. It is the only known technology that can convert cellulose into protein. Society benefits from converting what is now a cause of disease, groundwater contamination and greenhouse gases into valuable products.

y.pdf
(a) Ecosystems contain complex networks of interactions between organisms and their environment. (b) Organisms fall into different ecological roles including producers, consumers, and decomposers. Producers like plants make their own food through photosynthesis, consumers eat other organisms, and decomposers break down waste and dead material. (c) These roles are interconnected as one organism's waste becomes a resource for others, fueling nutrient cycling within the ecosystem.

2 2 food webs ii ms.ls2 [autosaved]
- 1. NEURONS!
- 2. Bell Work 2/2/2015 Explain how the different biotic components of ecosystems was part of today’s breakfast. If you didn’t have breakfast today, talk about a sample breakfast. Ex: I had Bacon (a ______ consumer) with toast (a producer) and a glass of milk (________ )
- 3. Welcome!Itinerary Abiotic Factors and Food Webs Announcements: To join class discussions on celly, check your Edmodo for the join link” Today’s Learning Target: I can visualize trophic interactions via a food web
- 4. NEW UNIT: Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect population AND… Evaluate competing designs for maintaining biodiversity and ecosystem services Δ = - +
- 5. Biological (Biotic) Components of an Ecosystem Introduced species - species moved by humans to new geographic areas, either intentionally or accidentally
- 6. Abiotic Factors in an Ecosystem There are 7 Abiotic Factors in an ecosystem: 1.) Topography 2.) Edaphic factors 3.) Climate 4.) Catastrophe 5.) Oxygen Availability 6.) Pollution 7.) Solar Energy Input TEC-COPS …like an ecosystem, they are composed of biotic and abiotic components…
- 7. Abiotic Factors in an Ecosystem 1.) Topography - The arrangement of the natural and artificial physical features of an area The organisms on a flat land compared to a hilly one will have different movement muscles to one another
- 8. Abiotic Factors in an Ecosystem 2.) Edaphic factors – Soil acidity, aeration, nutrition and water content levels will affect PRODUCERS – if the soil is too acidic, or too basic, plants will not grow.
- 9. Abiotic Factors in an Ecosystem 3.) Climate - Rain, wind, temperature play factors in plant and animal life. The amount of rain provides necessary water for photosynthesis and animal cellular processes Wind has an effect particularly in the types of plant life that grow in certain areas Temperature plays a key role in how rapidly plant and animal life is allowed to grow. Many animals cannot grow in certain temperatures.
- 10. Abiotic Factors in an Ecosystem 4.) Catastrophe - Natural (or otherwise) catastrophes can have devastating effects on an environment, killing off large populations or perhaps even leading to the extinction of them Examples of catastrophes: Tornado, Hurricane, Earthquake, Volcano, Tsunami
- 11. Abiotic Factors in an Ecosystem 5.) Oxygen Availability – The amount of oxygen available to consumers will limit their activity and availability.
- 12. Abiotic Factors in an Ecosystem 6.) Pollution – Pollution limits the growth and health of plant AND animal life.
- 13. Abiotic Factors in an Ecosystem 7.) Solar Energy Input – How much solar radiation does the ecosystem receive? Solar energy input has an effect on how much plant life is available for photosynthesis. Producers are the foundation of the food web. Sunlight also affects animal behavior, giving some animals cues for migration and reproduction
- 14. FOOD WEBS
- 15. What is a food web?
- 16. Your Task: With your shoulder partner, begin planning your model of an ecosystem that you are both familiar with. (River, Pond, Grasslands, Marine, Deciduous forest, etc) List as many biotic and abiotic factors as you can think of. For the biotic factors, list what biotic component (jenga block) they are (Producers, Primary Consumer, Secondary, etc) Organize this information in BOTH of your notebooks.
- 17. Ecosystem Complexity Ecosystems are much more complex than you would think.
