How might a ride in global temperatures affect the biosphere

heat

Explanation:The Sun, a source of heat, is the cause of winds (atmospheric currents) and water circulation (ocean currents), even if both are influenced by topog- raphy, the Earth's rotation, etc. By interacting with the atmosphere, hydrosphere and lithosphere (ground), the biosphere plays a determining role in the Earth's climate.

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.
