Phylogeny refers to the evolutionary descent of taxa. It refers to the relationship between ancestors and descendants and relationships among descendant taxa. It shows the lineage of taxa which can be summarized in a branching diagram called a phylogenetic tree.a. express some basic evolutionary relationships among groups of microorganisms, plants, and animals; b. illustrate the relationship of organisms with their environment; and c. analyze environmental factors contributing to biodiversity richness and loss

Which of the following is FALSE regarding phylogenetic trees? 1) The branch lengths on the tree are scaled to molecular (DNA) changes and/or time. 2)Phylogenetic trees have shown us that there is much more bacterial diversity compared to eukaryotes. 3) Phylogenetic trees show the evolutionary relatedness of different organisms. 4). The branch lengths on the tree depict abiotic and biotic factors affecting speciation.

Plants fix carbon dioxide from the air; fungi and animals use pre-existing organic molecules. C.
