Nitrogen is a major component by which plants use sun energy to produce sugars from water and carbon dioxide. (It is also a major component of amino acids)
The red algae was the plant group that includes the Ancestors of plants.

The features or characteristics of organic compounds include:
1. They contain covalent bonds and are mostly non polar in nature
2. Have lower boiling and melting points than inorganic compounds
3. Many organic compounds are thermally unstable, They decompose into simpler molecules when heated at fairly high temperatures
4. Most organic compounds are inflammable and burn exothermically in sufficient air to yield carbon dioxide, water and heat energy.
5. Most organic compounds being largely non polar are insoluble in water.
Phylogenetic trees show the evolutionary pathways and connections among organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms.
