Answer:
Molecular phylogenies have challenged this hypothesis and support the alternative hypothesis that they might be phylogenetic, coming from an intricate linage structure.
Explanation:
Psilotophyta were traditionally graded as monophyletic, vascular plants that resemble their immediate ancestor with gradual increases in complexity. However, Molecular phylogenies has challenged this classification by studying these vascular plants’ genetics and hereditary material. By analysing nucleotide and amino acid sequences, Molecular phylogenies have challenged the current topologies of whisk ferns as they might have evolved from more than one ancestor. Instead of descending from a single lineage, these fern-like vascular plants may be part of a taxon with not common ancestor.
Answer:
When an organism dies, decomposers decay the body extracting the last bit of energy from it. The common left over materials such as water, carbon dioxide, and minerals can then be reused by producers to make sugar through photosynthesis. Decomposers get energy through respiration, so they are heterotrophs.

It's caused by a group of molds, called mucormycetes. Individuals are infected after inhaling fungal spores found naturally in India's environment and soil.
