Ecosystems: Feeding relationships
Producers, consumers, and decomposers all play important roles in ecosystems. [1] Producers like plants and algae produce their own food through photosynthesis. [2] Consumers such as animals are heterotrophic and obtain carbon compounds by eating other organisms. [3] Decomposers including fungi and bacteria break down dead organic matter and release nutrients back into the environment.
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.
Our Environment
This presentation gives an idea about our ecosystem, our environment, it's various components, the flora and fauna and others elements related to it. It also explains about how our environment functions.
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.

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.
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.

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.
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.
Roles of Organisms in the Ecosystem
- An ecosystem is a community of living organisms that interact with each other and their non-living environment. It includes producers, consumers, and decomposers that carry out important roles. Producers like plants make their own food, while consumers eat other organisms and are classified as herbivores, carnivores, omnivores, predators, scavengers, or decomposers. Human activities like pollution, deforestation, and development can negatively impact ecosystems, but conservation efforts help restore and protect them. These include cleaning waterways, reforestation, reducing waste, and practicing the 5Rs of reduce, reuse, recycle, recover, and repair.
Dondoyano, glemefer
The food chain shows how organisms transfer energy by consuming other organisms. Producers like plants use photosynthesis to convert sunlight into chemical energy. Primary consumers eat producers, secondary consumers eat primary consumers, and tertiary consumers eat secondary consumers. All organisms eventually die and are decomposed by decomposers, recycling nutrients and completing the food chain. Disruptions to the food chain can impact populations if a food source disappears due to overhunting or overfishing.
Learning about ecology
Ecology is the study of organisms and their relationship with their environment. Ecologists study how species interact with each other and their surroundings. An ecosystem includes both biotic factors like living organisms and abiotic non-living factors that exist in an environment and interact, such as nutrients and energy cycles. Food chains show the transfer of energy from producers like plants through consumers to decomposers, but food webs better represent the complex reality. Pollution harms ecosystems by damaging organisms and toxic buildup in food chains, and governments work to prevent and control pollution through legislation while more remains to be done.
Abiotic biotic
The document defines an ecosystem as all living organisms in a region and their physical and chemical environment. It discusses biotic factors as living things and their remains/features, and abiotic factors as non-living components like rocks, oxygen, and water. Biotic and abiotic influences, like availability of resources, temperature, and interactions between species, impact populations and determine an ecosystem's carrying capacity, or maximum sustainable population size.
Energy flow in ecosystems
- Sunlight provides energy for most life on Earth through the process of photosynthesis, where plants, algae, and some bacteria use carbon dioxide, water, and sunlight to produce sugar and oxygen.
- Producers are organisms that convert sunlight into chemical energy through photosynthesis. Consumers eat other organisms for energy and include herbivores, carnivores, and omnivores. Decomposers and detritivores break down dead organic matter.
- Cellular respiration is the process where cells use sugar and oxygen to produce energy, carbon dioxide, and water. Energy transfers between organisms as they eat each other in food chains and food webs.
Trophic levels
Primary producers use energy from the sun or chemicals to produce organic molecules. Consumers rely on other organisms for energy and nutrients. There are different types of consumers including herbivores, carnivores, omnivores, scavengers, decomposers, and detritivores. Food chains show the transfer of energy between organisms through eating, while food webs show complex feeding relationships in an ecosystem. Trophic levels refer to the steps in a food chain, with primary producers at the base and increasing consumer levels above. Only about 10% of available energy is transferred between trophic levels.
Ecosystem and its components
This document defines an ecosystem as including all living and non-living interactions within a given area. It identifies biotic components as the living organisms and abiotic components as the non-living physical parts that affect organisms. Food chains and webs are explained as the transfer of energy from producers to various consumer trophic levels, with food webs being interconnected chains. Energy flows unidirectionally through the ecosystem from autotrophs to herbivores and other consumers.
Chapter 22 Ecosystems and the Biosphere
Producers, such as plants and some bacteria, are autotrophs that can manufacture their own food through photosynthesis or chemosynthesis. Consumers, including herbivores, carnivores, and omnivores obtain energy by eating other organisms or their byproducts. Decomposers break down dead and waste materials into simpler molecules and cycle nutrients in the ecosystem. Energy and matter transfer through ecosystems in food chains and interconnected food webs, with producers at the base providing energy and consumers at higher trophic levels.
The food chain
The document discusses the food chain within an ecosystem. It explains that producers, like plants, take matter from the environment to support life. Herbivores, the next link, eat plants. Carnivores eat other animals and are farther along the chain. Omnivores consume both plants and animals. Decomposers, such as fungi and bacteria, break down dead plants and animals, recycling nutrients. Each member plays an important role, and imbalance can cause problems for the ecosystem.

Ppt on ecosystem
An ecosystem is defined as a complex relationship between living organisms, habitats, and resources in a given area. Organisms are typically dependent on each other and their habitat for survival. Ecosystems can be natural or artificial. The components of an ecosystem include abiotic (non-living) factors like air, water and soil, and biotic (living) factors like producers, consumers, and decomposers. Producers harness energy from the sun via photosynthesis. Consumers consume other organisms for food, and decomposers break down dead organisms and waste. Food chains show the transfer of energy as organisms consume one another.
Unit 2 a ch 4 s1 ecosystems- everything is connected
The document discusses the key components and levels of organization in ecosystems studied by ecologists. It defines habitat, biotic factors (living things), abiotic factors (non-living things) as components of ecosystems. It also explains that biotic and abiotic factors influence each other. Finally, it outlines the levels of life studied, from organism to population to community to ecosystem to biome.
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.

An ecosystem consists of living organisms and their non-living environment. The habitat provides characteristics like temperature, seasons, water and soil that organisms are adapted to. All parts of an ecosystem are interconnected, as living things rely on each other and their habitat. Producers like plants and algae make their own food, consumers like animals feed on other organisms, and decomposers like fungi and bacteria break down dead remains. Humans are putting stress on ecosystems by overusing natural resources and causing pollution, extinction, and social injustice.
Ppt ecology of fish pond ecosystem
This document provides information about pond ecosystems. It discusses the key components of a pond ecosystem including producers, consumers, and decomposers. Producers in a pond include phytoplankton and aquatic plants that carry out photosynthesis. Primary consumers feed on producers and include zooplankton and insects. Secondary consumers are carnivores that prey on primary consumers, like small fish and frogs. Decomposers, such as bacteria and fungi, break down dead organic matter. The document also describes the food chains and energy flow within a pond ecosystem.
Ecosystems by Group1
An ecosystem includes all living and non-living things in a given area that interact with each other. Each organism has its own role, and ecosystems provide vital life-support services to humans like food, water, and air purification. However, ecosystems have been disrupted by both natural disasters and human activities.
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.

The paper analyzes the price effects of cash versus in-kind transfers using data from a randomized experiment in Mexico. It finds that:
1) Prices for goods decline more for in-kind transfers than for cash transfers, with the difference in price effects being statistically significant.
2) The price effects are larger in more remote villages, consistent with those villages having more closed economies and less competition.
3) The results provide empirical evidence that in-kind transfers can have larger impacts on prices than cash transfers due to introducing supply as well as demand for goods in local markets.

component of ecosystem
An ecosystem is defined as a community of living organisms (biotic) interacting with each other and their non-living (abiotic) environment. It includes producers, consumers, decomposers and their interactions within the physical environment. Producers like plants convert solar energy to food via photosynthesis while consumers feed on producers or other consumers. Decomposers break down dead organic matter and recycle nutrients. Ecosystems function by transferring energy from producers to consumers and recycling matter through decomposition. Habitat destruction like deforestation can threaten organisms by reducing food, shelter and resources, potentially driving some to extinction.

An ecosystem is a region with a recognizable landscape such as a forest, grassland, desert, or coastal area. The ecosystem is controlled by climatic conditions like sunlight, temperature, and rainfall. It includes both living organisms that depend on each other and non-living components like soil, air, and water. Resources in an ecosystem like light, nutrients, water, and habitat can be consumed by one organism and become unavailable to others. Key resources for plants include sunlight, nutrients, water, and space to grow, while animals rely on food and water.
Ecology ..
Ecology is the scientific study of interactions between organisms and their environment. The biosphere consists of all life on Earth and the areas where life exists. Ecology studies different levels of organization from populations and communities to ecosystems and biomes. Energy flows through ecosystems in food chains from primary producers like plants through various consumer levels. Nutrients are recycled through decomposition and enter the ecosystem again.
Ecosystem and its components
1. An ecosystem is defined as a community of living organisms (biotic factors) interacting with each other and their non-living (abiotic) environment.
2. The key components of an ecosystem include biotic factors like producers, consumers, decomposers and abiotic factors like air, water, soil, and sunlight.
3. Ecosystems function through energy flow, nutrient cycling, and interactions between organisms like predation and symbiosis. Ecosystem processes like photosynthesis and respiration are important for energy and nutrient exchange.
Ecosystem
An ecosystem consists of all the living organisms (biotic factors) in an area as well as non-living components (abiotic factors) interacting together. Key abiotic components include climate, soil, sun, water and air. Key biotic components include producers, consumers, and decomposers. Energy enters the ecosystem primarily from the sun and passes through food chains and food webs as organisms consume, and are consumed by, others. Decomposers break down dead organic matter and cycle nutrients back into the soil.
Ecosystem
An ecosystem is a community of living organisms interacting with each other and their non-living environment. A food web shows how energy and nutrients flow between organisms in an ecosystem through trophic levels. It consists of interconnected food chains with producers like plants at the bottom providing energy, a variety of consumers at higher trophic levels that eat other organisms, and decomposers that break down waste and dead organisms.
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.
Miller section 3.2 (producers & consumers)
Primary producers are organisms like plants, algae and certain bacteria that can capture energy from sunlight or inorganic chemicals and convert it into energy-rich compounds. They are essential to the flow of energy through ecosystems as other organisms consume them. Consumers rely on primary producers and other organisms for energy and nutrients. They are classified based on their food sources and include carnivores, herbivores, omnivores, detritivores and decomposers like bacteria and fungi. Consumer categories in nature are often not strict, as organisms may consume a variety of food sources.

Additionally, it explains the concepts of trophic levels in food chains and food webs, which represent the transfer of matter and energy between organisms in an ecosystem.
Energy flow in ecosystem
It is quite interesting to note that the only producer of food in the entire world is PLANT. All others are consumers, and depend only on plants to provide food to all the living organisms and species.
Energy flow in ecosystem
1) Energy from the sun powers photosynthesis in green plants, which convert carbon dioxide, water, and sunlight into glucose.
2) This chemical energy from glucose is transferred through ecosystems as organisms eat each other, forming food chains.
3) Producers like plants capture energy from the sun which is then consumed by primary consumers like herbivores, and passed up through secondary and tertiary consumers in a trophic pyramid, with decomposers recycling nutrients.

An ecosystem is a community of living organisms interacting with each other and their non-living physical environment. The lecture defines ecosystems and describes their key components and functions. Ecosystems have biotic factors like producers, consumers, and decomposers, as well as abiotic factors such as sunlight, water, temperature, oxygen, and soil. Producers convert solar energy to chemical energy through photosynthesis. Consumers feed on other organisms and each other, in a food chain. Decomposers break down dead organic matter and release nutrients. Key functions of ecosystems include energy flow, food chains, nutrient cycling, and the evolution of biodiversity. Students were assigned a group project to create an infographic poster explaining a specific
PPT2.2 Producers, consumers and decomposers.pptx
1) Producers such as plants and trees undergo photosynthesis, taking in carbon dioxide, water, and sunlight to produce oxygen and nutrients.
2) Consumers, which cannot produce their own food, feed on producers and each other. They are classified as primary consumers (herbivores), secondary consumers (carnivores), tertiary consumers, and omnivores.
3) Decomposers like bacteria and fungi break down waste and remains of plants and animals, releasing nutrients back into the environment for reuse by producers, thus completing nutrient cycles.
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.
structural component of ecosystem
This document summarizes the key structural components of an ecosystem, including biotic and abiotic factors. It describes the biotic components as including producers (autotrophs like plants), primary consumers (herbivores), secondary consumers (carnivores), and decomposers (bacteria and fungi). It notes that abiotic components provide the energy (sunlight) and materials (water, minerals, gases) that flow through the ecosystem. The document also explains the trophic levels and roles of different organisms within the food chain.
Interdependence in living beings.pptx
A food chain refers to the transfer of energy from one organism to another as each organism eats and is eaten. It typically involves producers, primary consumers, secondary consumers, tertiary consumers, and decomposers. Producers, like plants, get their energy from the sun. Primary consumers eat producers, secondary consumers eat primary consumers, and tertiary consumers are apex predators that eat secondary consumers. Decomposers break down dead organisms and waste to recycle nutrients back into the system.
Ecosystem
The document discusses the history and structure of ecosystems. It defines an ecosystem as a complex unit of living and non-living things that interact and exchange materials. Ecosystems have biotic components like producers, consumers, and decomposers, as well as abiotic components like soil, water, and nutrients. Producers use photosynthesis to convert sunlight into chemical energy, which consumers then use as food and decomposers break down dead remains, recycling nutrients for producers. Energy and matter flow through the ecosystem via these interactions and components.

- 2. Every participant in an ecosystem has an important part to play and if one becomes more dominant than the others, the ecosystem can develop problems.
- 3. • First, the producers. These are living things which take the non living matter from the environment, such as minerals and gases and uses them to support life. Green plants are considered producers and are at the beginning of the food chain. • Next are the consumers. These living things need the producers to their food. Animals which eat plants are called herbivores. They are considered consumers and are next in the food chain. Animals which eat other animals are called carnivores. They also considered consumers and are a link farther along on the food chain since they need the herbivores for their food. Animals and people who eat both animals and plants are called omnivores, and they are also part of the consumer piece of the ecosystem. • Finally, the last part of the ecosystem is the decomposers. These are the living things which feed off dead plants and animals and reduce their remains to minerals and gases again. Examples are fungi, like mushrooms, and bacteria.
- 4. PRODUCERS are autotrophic organisms that serve as a source of food for other organisms in a food chain. These include green plants, which produce food through photosynthesis, and certain bacteria that are capable of converting inorganic substances into food through chemosynthesis. Autotrophic Organisms: these are organisms that are capable of synthesizing its own food from inorganic substances, using light or chemical energy like green plants, algae, sea grass and many more.
