Paleontologists can identify organisms that may be ancient relatives of those living today. By looking at fossils they can also suggest how these organisms lived together in an ancient habitat. Few organisms become fossilized because the circumstances that an organism has to be in is very specific.

Terms matched with the right definitions.
1. An organism that can make its own food – Autotroph
2. A symbiotic relationship between two organisms in which one species benefits and no effect is apparent to the other species – Commensalism.
3. A cell that has a membrane-bound nucleus and/or organelles as its major characteristic -Eukaryote.
4. The study of organisms that are too small to be seen with the naked eye - Microbiology.
5. A disease-causing organism - A germ pathogen.
6. A one- or few-celled organism with chromosomes; may have characteristics of both animals and plants – Protist.
An autotroph is an organism that produces its own food from simple substances available in its environment. Autotrophs usually use inorganic chemical reactions or light energy in producing their food and are usually the producers in a food chain. Examples of autotrophs are plants and algae.
Commensalism is a type of relationship between organisms of two species where one organism benefits from the relationship and the other organism is not affected by it (neither benefits nor harmed).
Ricin comes under the category of functionally related toxins, in a combination known as RIPs (ribosome inactivating proteins). This disables ribosomes and stops the process of protein synthesis.
They directly associate with and inactivate the ribosomes or modify the factors taking part in the process of translation, generally the elongation step. These proteins bring about depurination of adenine at position 4324 in the 28 S rRNA.
This further inhibits the generation of a critical-stem-loop configuration to which the elongation factor is considered to combine at the time of the translocation step of translation. The ultimate outcome of this activity is the complete inhibition of cellular translation.
