An aquatic ecosystem is an ecosystem in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems.ome of the important abiotic environmental factors of aquatic ecosystems include substrate type, water depth, nutrient levels, temperature, salinity, and flow. It is often difficult to determine the relative importance of these factors without rather large experiments.
(Newser) â Here's a fun fact to throw around the Thanksgiving table: Lots of turkey farms use arsenic in their feed. Yes, that arsenic, the deadly poison, which can control stomach bugs in turkeys and fatten them up, explains NPR's Shots health blog.It can also show up in the turkey meat on the table in trace amounts.es, that arsenic, the deadly poison, which can control stomach bugs in turkeys and fatten them up, explains NPR's Shots health blog.

Arsenic trioxide is also important as a raw material for products containing arsenic. Because arsenic is an element like carbon and oxygen it does not break down in the environment into simpler substances-though it can change form and combine with other elements into molecules that have different chemical properties.Some forms of arsenic are quite toxic; others are less so.Most arsenic compounds are undetectable to the senses, since they have no smell or taste. But when arsenic is heated-by bright sunlight or in a laboratory experiment-it passes directly from its solid state to a gas and gives off a distinctive garlic odor.ost arsenic compounds are undetectable to the senses, since they have no smell or taste.
