Example- rabbit, which eats grass. Decomposers The organisms which break down the dead remains and waste products of organisms are called decomposers.
Decomposers break down the complex organic substances into simple inorganic substances in the soil which is used by the plants.

Deer Park is situated in which of the following place of Haryana?
Nahar Wildlife Sanctuary is located in which district of Haryana? Which one of the following bio-reserves of India is not included in the World Network of Biosphere Reserve? The fungi thrive at degree Celsius, which is the temperature prevailing when paddy is harvested and wheat is sown. How these decomposers are used on fields?
A liquid formulation is formed using decomposer capsules and fermenting it over days and then spraying the mixture on fields with crop stubble to ensure speedy bio-decomposition of the stubble.
The farmers can prepare 25 litre of liquid mixture with 4 capsules, jaggery and chickpea flour. The mixture is sufficient to cover 1 hectare of land. It takes around 20 days for the degradation process to be completed. Benefits of PUSA decomposers: Improves the fertility and productivity of the soil as the stubble works as manure and compost for the crops and lesser fertiliser consumption is required in the future.
It is an efficient and effective, cheaper, doable and practical technique to stop stubble burning. It is an eco-friendly and environmentally useful technology.

A food web is all of the food chains in an ecosystem.
Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid. Primary consumers, mostly herbivores, exist at the next level, and secondary and tertiary consumers, omnivores and carnivores, follow. At the top of the system are the apex predators: animals who have no predators other than humans.
Help your class explore food chains and webs with these resources. Plastic is ubiquitous in our everyday lives. Some plastics we can reuse or recycle—and many play important roles in areas like medicine and public safety—but other items, such as straws, are designed for only one use.
In fact, more than 40 percent of plastic is used only once before it is thrown away, where it lingers in the environment for a long, long time. It often breaks down into smaller and smaller particles, called microplastics, which can be ingested by both animals and people. Fortunately, there are things we can do to help—like stop using plastic bags, straws, and bottles, recycling when we can, and disposing of waste properly.
Use these classroom resources to teach about ocean plastics and check back for more coming later this year! Encyclopedic entry. Humus is dark, organic material that forms in soil when plant and animal matter decays. When plants drop leaves, twigs, and other material to the ground, it piles up.
