You are studying a mini-ecosystem that you created from samples of lake water, plants, and sediment. Your teacher tells you to drop about 10 sesame seeds on the top of the water because they will attract some interesting organisms. One week later, you see that the seeds are surrounded by white fuzz that is extending off of the seeds, and you conclude that the decomposing seeds have been colonized by:

The correct answer is : water molds.

Explanation:

Watermold is the member of oomycota known water mold produce asexual spores which uses the water surface for the movement

Watermold grow generally on dead, decomposing organic matter such as dead plants, animals and get their nutrition from these organic matter. The spores that and water molds colonies give appearance often as white fuzz.

In the given question the colony that most likely occur would be of watermold.

Thus, the correct answer is : watermold.

answer; /// i do believe its (heredity); good luck

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.
