The detrital food web involves consuming a dead animal for example, a vulture. The decomposing remains of the carcass become nutrients for the soil, thus returning the minerals back into the ground, possibly nitrates would be involved in the process.
The detrital food web consists of interconnected food chains that focus on the decomposition processes of nutrients in decayed organic matter. Detrital food webs, placed in comparison to a grazing food web, is more engaged with abiotic components of an ecosystem. Another distinction in detrital food webs is that the energy from producers flow directly to decomposers and detritivores.

The land and aquatic are the two types of global food webs.
The detrital food chain and grazing food chain are interconnected through the flow of energy and nutrients in ecosystems. In the grazing food chain, primary producers (like plants) are consumed by herbivores, which are then eaten by carnivores. Detritivores and decomposers in the detrital food chain break down organic matter from dead plants and animals, recycling nutrients back into the soil, which supports primary producers, thus linking the two chains. This interconnectedness highlights the importance of both chains in maintaining ecosystem health and nutrient cycling.
Food web.
A food web consists of one part of a food web. For example a food web would be: Carrot- Rabbit- Fox- Worm/ Decomposer. A food web is multiple food webs together. The multiple food chains 'web' together forming a food web.
Detrital rocks are sedimentary rocks that are composed of particles of weathered and eroded igneous, metamorphic, or other sedimentary rocks that have been deposited, compacted, and cemented together. Sandstone, conglomerate, shale, and breccia are examples of detrital sedimentary rocks.
A grazing web primarily involves herbivores that feed on living plant material, forming a direct link between producers (plants) and primary consumers (herbivores). In contrast, a detrital web focuses on the decomposition of dead organic matter, where detritivores and decomposers, such as fungi and bacteria, break down dead plants and animals, recycling nutrients back into the ecosystem. Essentially, grazing webs emphasize living biomass interactions, while detrital webs highlight the importance of decomposition and nutrient cycling.
they are not in the food web
An aquatic food web is a food web that involves marine life.
Detrital rocks form from the accumulation and cementation of sediment grains derived from the weathering and erosion of pre-existing rocks. The size, shape, and composition of the sediment grains help to identify the environment in which the detrital rock formed. Detrital rocks include sandstone, shale, and conglomerate.
Shale is a detrital rock, meaning it is composed of fragments of other rocks and minerals. It forms from the compaction and cementation of silt and clay particles. There are organic-rich shales as well, but they are still considered detrital in nature.
