The right answer is Lichen.
In ecology, a pioneer species is one of the first forms of life that colonize or recolonize a given ecological area.
Lichens are composite organisms resulting from a symbiosis between at least one heterotrophic fungus called mycobionte, representing 90% of all, and microscopic cells with chlorophyll (green algae or cyanobacteria autotrophic for carbon) called "photobionts" .
Correct answer: D) From bacteria living in their roots
Nitrogen is an essential plant nutrients, but it is metabolically unavailable to higher plants and animals. It is available to some species of microorganism by biological nitrogen fixation in which nitrogen is converted to ammonia with the help of enzyme dinitrogenase.
The process of breaking apart the two atoms in a nitrogen molecule is called nitrogen fixation. Plant obtain the nitrogen they need from the soil which is already fixed by the bacteria and archae.

Answer:
The rock type, newspaper ,
cotton or plaster of Paris to collect the fossil
Method of collection .
Documentation or labelling.
Magnifying glasses.
Explanation:
Fossil is fragile as it contain the remains of dead of plants and animals on it. Fossil can be collected from sedimentary rocks instead of metamorphic rocks because sedimentary rocks contain strata or layers of fossils.
The method of collecting fossils entails how the fossil is collected and it should be wrapped in news paper, aluminum foil or plaster of Paris so as to preserve the imprints of the remains of dead plants and animals.
The collected fossils should be labelled properly and well documented to avoid missed up or loss of some certain information using pen or paints.
Magnifying glass can be used to view it.
