saprotrophs
Animals do not use hydrogen directly. However, some microbes living in the gut of animals can use hydrogen as an energy source through a process called methanogenesis. In this process, hydrogen is used by microbes to produce methane gas that is then expelled by the animal.
The type of rock that forms where the remains of plants and animals are deposited in thick layers are called organic sedimentary rock.
Sedimentary rocks formed from the remains of plants and animals are called organic sedimentary rocks. Examples include coal, formed from the remains of plants, and limestone, formed from the shells of marine organisms.
FOSSILS ! comes from latin word Fossus which means "having been dug up". Anything that was once a living organism from a past geologic time is considered a fossil.
A rock formed from the remains of living things is called a sedimentary rock. This type of rock is formed through a process known as lithification, where sediments such as dead plants or animals accumulate and become compacted over time. Examples include limestone, coal, and chalk.
Most fungi live by decomposing the remains of plants, animal, and microbes found in soil. That is why most fungi are called ?
Animals and fungi that must depend on autotrophs for their food energy are called consumers. These consumers are also called heterotrophs.
worms and microbes
Fungus is the organism that feed on dead an decaying matter.Animals that feed on dead remains are called Scavengers eg Crow,Vulture.
The disease causing microbes are called pathogens.
Saprotrophs
They eat all dead and/or decomposing animals, they're also called carrion.
A microbiologist who deals with the microbes of animals like farm animals or pets etc. is called veterinary microbiologist. In this a microbiologist studies the effect of microbes on the animals and the disease caused by them.
A paleontologist studies fossilized remains of plants and animals.
It is called humus.humus
It is called humus.humus
When plants and animals (any living matter) decay, their remains are in the soil, in the material called humus.
