Solution
The correct option is D
Decomposers
The correct answer is decomposers.
The explanation for the correct answer
Decomposers break down the bodies of dead organisms into simple nutrients without directly eating them.
They are called saprotrophs. (Sapros means ‘rotten’.) Fungi and bacteria are examples of decomposers.
Decomposition of organic matter helps to return nutrients to the environment.
The explanation for the incorrect answer
Producers make their own food using substances that are available in their environment. Plants and some microorganisms (such as phytoplankton in the sea) make their own food. e Since producers make their own food, they are called autotrophs.
Consumers cannot make their own food. They depend directly or indirectly on producers for nutrition. They are called heterotrophs. (Heteros means ‘other’.)
Primary consumers eat plants. Herbivores eat only plants. Some examples of herbivores are deer, cow, rabbit, elephant, and zebra
Most decomposers are microscopic organisms, including protozoa and bacteria. Other decomposers are big enough to see without a microscope. They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes.
, nutrients get added back to the soil or water, so the producers can use them to grow and reproduce. Most decomposers are microscopic organisms, including protozoa and bacteria. Other decomposers are big enough to see without a microscope.
Nutrients in the soil are returned by adding fertilizers and manures. Fertilizers and manures contain plants nutrients and minerals like nitrogen, phosphorus and potassium.
this is called crop rotation. for example, wheat or rice users up large amounts of nitrogen from the soil. this nitrogen can be naturally replenished if the next crop grown is that of a legume, like a pea or groundnut. bacteria called rhizobium are present in the nodules of roots of leguminous plants.
Thanks to decomposers, nutrients get added back to the soil or water, so the producers can use them to grow and reproduce. Most decomposers are microscopic organisms, including protozoa and bacteria.
In nature, these nutrients would be returned to the soil with the natural decomposition of plant material. Composting takes that organic material and, in a confined space (composting bin), recreates these processes under optimal conditions.
Bacteria help to break down organic residues, freeing up nutrients like carbon and nitrogen that other living things can use. Specialized bacteria called rhizobia partner with plant roots to fix nitrogen in the soil. Fungi also help to decompose organic matter.
Nutrients can be replenished in the following ways: Fertilisers and manures contain plant nutrients such as nitrogen, phosphorous and potassium, etc. So, when fertilisers and manures are added to the soil in the fields, then the soil gets enriched with nutrients like nitrogen, phosphorous and potassium, etc.
Topsoil replenishes itself through natural processes such as weathering, erosion, and the decomposition of organic matter. Weathering breaks down rocks into smaller particles, contributing to the mineral content of the soil. Erosion brings in new sediment and nutrients from surrounding areas.
Nutrients get into the soil many different ways: from decomposed animal waste and dead plants, the atmosphere, weathering of rocks and bacteria conversions. When soils are used to grow foods, the soils need to be kept healthy, as a lot of nutrients are taken up by plants and not replaced.
Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; by micro-dose ...

It takes organic waste and turns it into nutrient-rich humus that can be used by plants. Composting is a way of returning to the soil what we deplete with traditional gardening practices. The most significant benefit of adding organic material (compost) to your soil is that it improves the soil itself.
Protecting a soil from these losses, and regenerating the nutrients lost by adding crop residues (straw, cornstalks, other stems, and roots), manure, and fertilizer materials (ash, phosphate rock, bone, chemical fertilizers) are therefore important strategies used by food producers to sustain production.
