Yes they are, they have DNA in them and DNA is organic
As grass is or has been alive, yes. Organic matter comes from organisms, or things that are or have been alive as opposed to lifeless.
Organic matter (or organic material) is matter that has come from a once-living organism; is capable of decay, or the product of decay; or is composed of organic compounds. The definition of organic matter varies upon the subject it is being used for.
A scavenger is an animal that feeds on decaying organic matter and refuse. Examples include vultures, crows, and certain types of beetles. They play a vital role in recycling nutrients in the ecosystem.
Scavengers are organisms that feed on dead or decaying organic matter. They play an important role in ecosystems by helping to recycle nutrients and break down organic material. Examples of scavengers include vultures, crows, and hyenas.
Bacteria that live on dead organic matter are called saprophytic or saprotrophic bacteria. These bacteria break down and decompose the organic material, helping to recycle nutrients back into the environment.
The isotope of carbon is used to date the ancient fossils. Since every living creature had organic matter and carbon is an integral part of that organic matter, it is conventional to use carbon isotope.
The science of how fossils form: what happens to organic matter, its traces and the organisms themselves after death is called: taphonomy
No, fossils are dead, and have no biological action. Prior to fossilisation, an organism may have itself been partially broken down by decomposers, and the decomposing agents may themselves be fossilised (fossil worms, beetles and fungi are such examples).
Clastic sedimentary rocks, like conglomerate and sandstone.
Fossils are the remains of plants and animals that have been turned to stone.
Fossils include any organic thing which has either made an impression which has turned to stone, or has had its body parts replaced by minerals so it is a stone copy of something. An example is petrified wood.
No, they are organic compounds.
Five types of fossils found in rocks are petrified fossils (minerals replace organic matter), mold fossils (imprint of an organism), cast fossils (mold filled with minerals), carbon films (thin layer of carbon residue), and trace fossils (evidence of organism's activity).
Minerals do not contain organic matter such as fossils, plants, or animals. Minerals are inorganic solids with a specific chemical composition and crystal structure.
Fossils
No. For it to be organic there would have to be pieces of once living things in it such as fossils.
Bacteria that decompose dead organic matter are called decomposers or saprophytic bacteria. They break down complex organic compounds into simpler substances, which can then be recycled in the ecosystem. Examples include species of Bacillus, Clostridium, and Pseudomonas.
