Methane hydrates in the ocean are a significant source of methane . true or false

True

A methane hydrate also called as methane ice, is a reservoir of methane inside the deep ocean. The methane in the methane hydrate is covered by frozen water. It can be defined as methane gas trapped inside the cage like crystal lattice prepared by the water molecules. Methane is produced in the bottom of the ocean when the organic matter from dead plants and animals gets trapped between the layers of earth. These are decomposed and broken down by the microorganisms and heat present between the earth layers. Additionally, the fermentation of organic matter also takes place, which is carried out by methaneogen Archea to produce methane. The methane produced is a source of valuable natural gas. Therefore, methane hydrate is searched in the bottom of the ocean in order to obtain methane.  

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
