Deep Water Zone And Bottom Zone example essay topic

1) Describe abiotic factors (type of climate, amount of rainfall) a. The depth of water or distance from the shore: the depth of water in return determines the amount of light an underwater organism receives b. The latitude of the freshwater biome: the latitude determines the distinctive characteristics. c. Water chemistry: especially salts, nutrients, and oxygen these are the things on which life depends. For example communities close and far from shore differ greatly. d. The amount of dissolved salt: Large factor in determining the difference in a freshwater and a marine biome.

2) Soils a. The soils in these areas are of (soft) mud and silt. These soils (sediments) are mainly found on the bottom of the freshwater source. 3) Water Details (Two types) The water of a freshwater & estuary (wetland formed where rivers meet the sea) is a mixture of both salt and fresh water a. Flowing water: consists of rivers, streams, creeks, and brook- Most flowing water systems begin in mountains or hills, most often springing up from an underground water source.

At the starting point of the river little plant life is available. However, further downstream the water may transport more slowly through flat areas creating homes for beavers, turtles, and otters. b. Standing Water: most common examples are lakes and ponds- The circulation of water throughout the ecosystem and within the standing water itself heat, oxygen, and nutrients are distributed. The lakes contain no rooted plates on the whole bottom. 4) Common Plants and Animals a. Frogs g.

Channel Catfish m. Plankton b. Lizards h. Mussels n. Algae c.

Beavers i. Crayfish o. Water Lilies d. Snakes j. Largemouth Bass p. Cattails e.

Water bugs k. Carp q. Water Moss f. Crayfish l. Bluegill r. Duckweed 5) Geographic Details- a.

The freshwater and estuary is found all over the world. Lakes, ponds, rivers, and etc. are found widely and in great number on all of the world's continents with an exception of Antarctica. 6) Other pertinent information- a. Algae can pollute water if to plentiful, and it can also cause "fish kill". b. Amount of dissolved salt is measured in parts per thousand. Freshwater is about.

5 ppt or less. c. The area is separated into four different zones, the shallow water zone (near the shore), open water zone, deep-water zone, and bottom zone (the bottom of the freshwater sources). Out of all these zones, the shallow water zone will be the warmest because it is exposed to the most light. The bottom zone is the coldest because very little sunlight gets to it.
