There are three main groups to consider when looking at the circle of life in an ecosystem. The groups are producers, consumers, and decomposers. These groups are based on how the organism obtains food. Producers, consumers, and decomposers all interrelate in food chains and food webs and are dependent on one another for survival.
Decomposers are any organism within a food chain that break down organic material, such as bacteria and fungi. Along with producers and consumers, they play an important role in the food chain. Without decomposers, dead animals and organisms would not be recycled into other living matter.
Students then explore the roles of producers, consumers, and decomposers within in a ecosystem. At the end of the lesson, students reflect and apply their new understanding of ecosystem roles by classifying the living organisms in the Yellowstone ecosystem. Next Generation Science Standards This lesson will support the following NGSS Standard (s).Producers are plant organisms that nourish themselves using photosynthesis, converting light into energy. Consumers feed on producers. Many herbivores fit into this category, surviving off grass and berries. Decomposers are organisms that feed on dead or decaying organisms.Prior to today's lesson, I drew the Producer (grass), Consumer (rabbit), and Decomposers (fungi and bacteria) on the poster to save time by simply projecting and sketching clipart from the internet. During this poster-making time, students participate by sharing their thinking and by taking notes in their journals: Student Notes.
Producers, consumers, and decomposers all interrelate in food chains and food webs and are dependent on one another for survival. Producers They do not have to obtain energy from other organisms.
All living organisms can be divided into three categories; producers, consumers, and decomposers. These terms describe what types of food the organism consumes and help us know how they go about securing their food source. Producers are living organisms that are able to make their own food through a process called photosynthesis. Plants use sunlight, carbon dioxide, and water to make food.
Producers are generally green plants and other photosynthetic bacteria which produces various organic substances such as carbohydrates, proteins etc. with the help of water, soil and light energy. Consumers depend for their nutrition on the organic food produced by the green plants Decomposers bring about the decomposition of dead plants and animals and return various important minerals for.
Decomposers are small living things that eat everything from waste and garbage to dead animals. Examples include worms, mushrooms, some insects, and tiny bacteria.
The food web has many intercrosses and linkages among the various species (producers and consumers) present in it. This means that the various food chains in an ecosystem do not operate in isolation (or alone). In this food web, we can see a network of numerous pathways along which the food (or energy) flows within grassland community. This food web starts from the plants which is a producer.

But it is still vital to life, because it contains chemicals that are the basic building blocks of all living things. These chemicals get recycled into the food web with the help of organisms called decomposers. Breaking it down. Decomposers are organisms that break down dead plants or animals into the substances that plants need for growth.
This Producers, Consumers, Decomposers (3-5) Lesson Plan is suitable for 3rd - 5th Grade. Young scholars gather evidence to explain that organisms in an ecosystem are tied together by their need for energy. They see that decomposers break down dead organisms and wastes and release the nutrients they contain into the soil.
Cross-connecting food chains consisting of producers, consumers, and decomposers, detritivores, or both. Term. Grazing food web: Definition. Cross-connecting food chains in which energy flows from plants to an array of herbivores, then carnivores. Energy captured by producers flows directly to consumers. Term. Detrital food web: Definition. Cross-connecting food chains in which energy flows.
Consumers have to feed on producers or other consumers to survive. Deer are herbivores, which means that they only eat plants (Producers). Bears are another example of consumers. Black bears are omnivores and scavengers, like skunks and raccoons, which means that they will eat just about anything. In a forest community, Black Bears will eat blueberries, bugs, acorns, and many kinds of nuts.
In this lesson sequence, students learn about producers, consumers (including carnivores, herbivores, and omnivores), and decomposers. As a class, they return to the Schoolyard Ecosystem Poster-Size Explanatory Model and add labels for the producers, consumers, and decomposers present there. They then learn about the producers, consumers, and decomposers that are present in their ecosystem.
