Question: Choose one of the pollutants listed: Lead, Nitrous oxide, Carbon monoxide. Create a diagram that shows the flow of your chosen pollutant through the Earth’s ecosystem. The diagram needs to show the complete cycle, beginning to end for your chosen pollutant. Include where or how the pollutant is produced, why the pollutant is produced, how the pollutant enters abiotic and biotic factors of the ecosystem, and how often the pollutant produced.

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.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
