Decomposers and scavengers break down dead plants and animals as well as waste, which provides nutrients to plants and prevents dead matter from accumulating. Scavengers like flies and wasps eat dead organisms, while earthworms eat dead plants. Once scavengers are done, decomposers like fungi and bacteria further break things down. Different decomposers specialize in breaking down different materials like meat or plant matter.

Food Chain and Food Web
A food chain shows how energy flows between organisms as one organism eats another. A food web shows multiple interconnected food chains within an ecosystem. Producers like plants use sunlight to make their own food, while consumers eat other organisms and decomposers break down dead organisms. Energy is lost at each transfer between trophic levels according to the 10% law.
Food chain
This document provides information about food chains. It begins by defining a food chain as a sequence of organisms through which energy flows as each organism obtains energy from the one below it in the chain. Producers, such as plants, are at the bottom of the food chain as they can produce their own food. Herbivores, as primary consumers, eat the producers. Carnivores eat herbivores or other carnivores. Omnivores both eat plants and other animals. Decomposers, like fungi and bacteria, break down waste and dead organisms, recycling nutrients in the ecosystem. The document includes examples of food chains and defines the roles of producers, consumers, and decomposers. It also
Ecology ppt
This document summarizes key concepts in ecology. It defines ecology as the study of interactions between organisms and their environment. It describes producers as organisms that use sunlight or chemical energy to produce food, including plants, algae and photosynthetic bacteria. Consumers rely on producers and other organisms for food and include herbivores, carnivores and omnivores. Decomposers break down dead organic matter. Food chains and webs show how energy flows through ecosystems from producers to different trophic levels. Ecological pyramids illustrate the decrease in available energy and biomass at higher trophic levels. The document also discusses ecological interactions like competition, niches, predation, and symbiotic relationships between species.
Eco system
An ecosystem consists of biotic and abiotic components that interact with each other. Biotic factors include living organisms like plants, animals, and microbes, while abiotic factors refer to non-living physical and chemical elements like water, soil, sunlight, temperature, and minerals. Organisms depend on each other through food webs, with energy transferring between trophic levels from producers to primary, secondary and tertiary consumers. Ecosystems also cycle nutrients through the actions of decomposers which break down organic matter. Examples of ecosystems include forests, grasslands, freshwater and marine environments.
Decomposers
Decomposers play an important role in nutrient cycles by breaking down dead or waste organic matter and recycling nutrients back into the environment. There are many types of decomposers including bacteria, fungi, and various invertebrate and vertebrate animals. Decomposers thrive in warm, moist environments like forests and grasslands where decomposition rates are highest.
Decomposers
Decomposers are organisms such as bacteria and fungi that break down dead or decaying organisms and recycle nutrients in an ecosystem. They carry out the natural process of decomposition by releasing enzymes that digest dead matter and make nutrients soluble and available to other organisms. Examples of decomposers include fungi, bacteria, earthworms, flies, and wasps. Without decomposers, dead organic material would accumulate in ecosystems.
Energy transfer in the ecosystems
This document discusses energy transfer in ecosystems through food chains, webs, and pyramids. It explains that producers like plants obtain energy through photosynthesis, and consumers obtain energy by eating producers or other consumers. A food chain outlines the sequence of energy transfer from the sun to producers to primary, secondary, and tertiary consumers. Scavengers and decomposers also play roles in recycling nutrients and matter back into the ecosystem.

Ecology notes ppt
Ecology is the scientific study of interactions between organisms and their environments, focusing on energy transfer. Key concepts in ecology include interactions within and among populations, nutrient cycling through ecosystems, and effects of natural and human activities. Ecosystems consist of biotic communities of interacting populations that inhabit a common environment and abiotic factors with which they interact. Energy and matter cycle through ecosystems via producers, consumers, and decomposers in food webs and nutrient cycles. Toxins can biologically magnify and increase in concentration as they move up food chains.

It then lists and briefly defines 18 specific areas that biology can be divided into, such as anatomy, bacteriology, cytology, and ecology. It emphasizes that many biology terms are derived from Greek or Latin roots to help determine meaning. Finally, it provides an assignment related to the material covered.
Class 10-chapter-15-our environment
The document provides information on different types of wastes, ecosystems, and environmental issues. It discusses:
1) Biodegradable wastes such as food and paper break down naturally, while non-biodegradable wastes like plastics persist and can pollute the environment.
2) An ecosystem includes both biotic (living) and abiotic (non-living) components that interact, along with food chains connecting producers, consumers, and decomposers.
3) Environmental problems arise from pollution and depletion of resources. The thinning ozone layer allows more UV radiation to reach the Earth's surface, increasing health risks, while waste disposal methods must account for different waste types.
Introduction to Biology
Living things have several key characteristics:
1. They are made of cells, the basic units of life.
2. They obtain and use energy. Autotrophs like plants make their own food through photosynthesis, while heterotrophs like animals consume other organisms for food.
3. They grow, develop, and reproduce. Multicellular organisms grow by adding more cells through mitosis and development, while both unicellular and multicellular organisms reproduce sexually or asexually.
Cycling of Matter in Ecosystems
The document discusses several biogeochemical cycles, including the water, carbon, and nitrogen cycles. These cycles describe the continuous movement and exchange of substances between living organisms and their inorganic environment. Specifically, it notes that the water cycle involves the processes that move water through the environment, the carbon cycle involves the exchange of carbon between the atmosphere, organisms, and carbon deposits, and the nitrogen cycle describes how nitrogen is converted between different forms and moves between organisms and the atmosphere.

Classification of Living Things
This document provides an overview of taxonomy and the classification of living organisms. It explains that taxonomy is the scientific study of naming and grouping organisms based on similarities. A standard 7-level classification system was developed by Carolus Linnaeus, with domains, kingdoms, phyla, classes, orders, families, genera and species. Organisms are grouped into six kingdoms - Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia - based on their cell structure, number of cells, and method of feeding. The document describes the defining characteristics of each kingdom.
Biological classification
Biological organisms are classified in a hierarchical system to reflect evolutionary relationships. The classification system has seven main levels from broadest to most specific: kingdom, phylum, class, order, family, genus, and species. This system allows scientists to organize the diversity of life and compare new organisms to existing groups. Examples are provided of the full seven-level classifications for several organisms, like Homo sapiens for humans and Panthera leo for lions.

Is it-living-worksheet-1
This document asks questions about the characteristics of living things like birds and flowers. It asks whether they grow, reproduce, move, breathe, make waste, and what food they need. The questions are assessing whether birds and flowers display the key characteristics of living things, such as growth, reproduction, movement, respiration, excretion, and needing food or energy from their environments.
Characteristics of life
All living things exhibit six key characteristics: 1) organization, with levels ranging from cells to organ systems; 2) emergent properties at each level that allow more complex functions; 3) maintenance of homeostasis through responses to stimuli and adaptations; 4) reproduction, either asexually or sexually; 5) growth as cells divide and specialize; and 6) development of specific cellular functions. These characteristics distinguish living things from non-living systems.
Levels of classification
This document provides information on biological classification systems. It discusses why classifying living things is important, provides a brief history of classification methods, and describes the current system of classification. The current system is based on 3 domains - Bacteria, Archaea, and Eukarya - which are further divided into kingdoms based on characteristics like cell structure, nutrition, and whether organisms are unicellular or multicellular. The 6 kingdoms are Bacteria, Archaea, Protista, Fungi, Plantae, and Animalia. Each kingdom has distinguishing features that are described.
Ecosystems, biotic and abiotic factors
This document introduces the concepts of ecology, ecosystems, biotic and abiotic factors. It defines ecology as the study of relationships between living and non-living things in environments. An ecosystem includes all biotic factors such as plants, animals and microbes as well as abiotic factors like air, water and soil. Biotic factors interact with each other and abiotic factors in complex ways.

Living and non-living things
- Living things have characteristics called life processes that distinguish them from non-living things. These processes are represented by the mnemonic "MRS. GREN" or "MRS. NERG".
- The life processes are movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition. All living things exhibit these processes, taking in nutrients and exchanging gases while growing, responding to stimuli, and reproducing.
- Non-living things may exhibit some similar behaviors but do not perform all the life processes, such as respiration. This distinguishes living from non-living entities.

How living things interact (part 1)
This document discusses ecosystems and the interactions between living and non-living things within an ecosystem. It explains that an ecosystem is a place where living things like plants and animals interact with non-living things like water, air, soil, and sunlight. It describes the roles of producers, consumers, and decomposers - with producers being plants that produce their own food, consumers being animals that eat other plants or animals, and decomposers like worms and bacteria that break down dead organisms and cycle nutrients in the ecosystem.

Some key words related to EED
Decomposers break down dead and decaying organisms through decomposition. They are heterotrophic, using organic substrates for energy and growth. Examples include fungi and worms. Scavengers search out dead animal and plant biomass to feed on, playing an important role in ecosystem decomposition. Examples are vultures, beetles and raccoons. Predation results in the death of prey that is hunted or attacked by a predator for consumption. Carnivores are organisms that obtain energy and nutrients mainly from eating animal tissue.

This document discusses the differences between living and non-living things. It defines living things as those that are born, grow, die and perform vital functions like nutrition, interaction and reproduction. The five kingdoms of living things are introduced as plants, fungi, animals, algae and bacteria. Each kingdom is then described in more detail, focusing on how they obtain nutrients, reproduce and interact with their environments. Key animal classifications like vertebrates and invertebrates are also outlined. Ecosystem concepts such as habitats, populations, communities and food chains are defined.
Ecosystems: Food chain
Producers such as trees feed on sunlight and water and provide nutrients to other living things. Consumers include animals that are heterotrophic and eat other organisms to survive. There are three types of consumers: herbivores that eat producers, carnivores that eat other consumers as hunters or scavengers, and omnivores that eat producers, consumers, and sometimes decomposers. Decomposers such as fungi and bacteria decompose remains of other organisms and release nutrients into the soil. A food chain shows the relationships between producers, consumers, and decomposers.

Scavengers like flies and wasps first eat dead animals, breaking them into small bits. Then decomposers like bacteria and fungi take over to fully decompose the remains. Decomposers are crucial for breaking down waste and recycling nutrients back into the soil, without which plants would not receive nutrients and waste would overaccumulate on Earth. Examples of decomposers include fungi that break down organic materials, molds, mildews that decompose plants, bacteria that eat and digest tissues, and insects like cockroaches and springtails that further break down waste to be consumed by bacteria or eat decaying organic matter.
HOW DO LIVING THINGS INTERACT?
This document provides an overview of ecosystems and the interactions between living and non-living things within an ecosystem. It explains that an ecosystem is a place where living and non-living things interact, and can vary in size from small ponds to large oceans. It describes the key roles of producers (plants), consumers (animals) and decomposers (bacteria, fungi, worms). Producers produce their own food, consumers eat other plants or animals, and decomposers break down dead organisms and return nutrients to the soil.
flow of energy.pptx Environmental science
This document describes the different types of organisms in an ecosystem and their roles. It explains that producers, such as plants and algae, use energy from sunlight or chemicals to produce food. Consumers, such as animals and fungi, eat the producers or other organisms. Decomposers, like bacteria and fungi, break down dead organisms and waste and release nutrients back into the environment for producers to use again. Together these groups transfer energy through food chains and webs in ecosystems.
other living things: fungi, bacteria and algae
This document provides information about other living things besides plants and animals, including fungi, bacteria, and algae. It states that fungi are decomposers that break down dead plants and animals to absorb nutrients, while bacteria come in different shapes and sizes and can both cause diseases or aid digestion. Algae, like plants, are able to carry out photosynthesis. The document also defines several key words related to different types of organisms.
Ecosystem
An ecosystem is a place where living and non-living things interact, and can exist in various environments from wet to dry and small to large. In an ecosystem, living things depend on each other and non-living things like water, soil and sunlight. Producers like plants make their own food through photosynthesis, while consumers like animals obtain food by eating other organisms, and decomposers like worms break down dead plants and animals and return nutrients to the soil.

Protist and bacteria presentation
Bacteria and protists are single-celled organisms. Bacteria come in different shapes - rod, spiral or sphere. They reproduce through binary fission. Protists are more complex than bacteria with organelles. They include algae, protozoans and other organisms. Protists obtain food through photosynthesis, consuming other organisms, or parasitism. They maintain water balance through osmosis and contractile vacuoles. Protists sense and react to their environment through structures like eyespots.
Bacteria
This document provides information about bacteria, protists, and fungi. It describes the key properties and life activities of bacteria, including how they obtain energy, reproduce through binary fission, and can be either helpful or harmful. It also outlines the defining features of protists, including different types of algae and protozoans. The document explains how protists obtain and digest food, maintain water balance through osmosis and contractile vacuoles, and reproduce. Fungi are also mentioned but not described.

Temple of Asclepius in Thrace. Excavation results
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

Decomposers
- 1. Decomposers Submitted by: Yobhel Selegria Submitted to : Ms. Elvi Navezaga
- 2. • Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the Plants would not get essential nutrients, and dead matter and waste would pile up. • There are two kinds of decomposers, scavengers and decomposers.
- 3. • Scavengers are animals that find dead animals or plants and eat them. While they eat them, they break them into small bits. In this simulation, Flies, wasp and cockroaches are scavengers. Earthworms are also scavengers, but they only break down plants.
- 4. • Once a scavenger is done, the decomposers take over, and finish the job. Many kinds of decomposers are microscopic, meaning that they can't be seen without a microscope. Others, like fungi, can be seen. • Different kinds of decomposers do different jobs in the ecosystem. Others, like some kinds of bacteria, prefer breaking down meat or waste from carnivores.
