The amount of organic matter in bottom sediments is particularly important to deposit feeders. Deposit feeders extract organic matter from sediment. The amount of detritus depends on the grain size, and the grain size effects the amount of oxygen available in sediment. The oxygen in sediments is used up by respiration of animals and more importantly decay bacteria]]> 2018-05-01 17:54:02 UTC https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256973111 19vochelliwp https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256973532 The most important part of living in this area is the size of the sediment particles. All of these sediments may be made up of sand, mud, silt, clay, and more. The more coarse the definition of the sediment, the quicker the water with flow through. The more fine the definition of the sediment is, the slower the water will flow through. When it is not sorted well, water ay be blocked. ]]> 2018-05-01 17:54:50 UTC https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256973532 skylahmendoza https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256974513 Animals that live on soft bottoms lack solid attachment sites. Most sediments are made up of a mixture of different particle sizes. Sediment composition is directly related to the degree of water motion.Fine sediments remain suspended with even a small amount of water motion. Places with stronger waves and currents have coarser bottom sediments.]]> 2018-05-01 17:56:47 UTC https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256974513 19reedan https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256974788 Certain animals have symbiotic bacteria that help them live in low-oxygen sediments.]]> 2018-05-01 17:57:21 UTC https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256974788 19vochelliwp https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256975206 2018-05-01 17:58:15 UTC https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256975206 19reedan https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256975250 Many soft-bodied animals use their body the way clams use their feet.

They found this area as their place to live and grew a trophic role and niche. They can also deal with the harsh sunlight when exposed out of water, and also can bear the salinity of the water when overrun with it.
In the right conditions, seagrasses form dense beds. And it is often hard for them to attach to the ground. Below the surface, there is no sunlight or oxygen, which means there is no photosynthesis. What lies down there are infauna and anaerobic bacteria that rely on anaerobic respiration for survival, and also feed off of detritus and DOM. Bioturbators are also helpful in this environment, they burrow and turn over the sediment, which "disturbs it", by oxygenating it. Many plankton, detritus, and DOM often wash up to these regions due to their nature of being lightweight. Sand dollars, worms, and birds often hunt in these areas as it is shallow and easy to grab their food.]]> 2018-05-01 18:03:39 UTC https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256977739 skylahmendoza https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256978631 Soft bottoms occur where sediments accumulate. Soft bottoms are unstable and constantly shift in response to waves, tides, and currents. Soft bottom organisms do not have solid place for attachment.Sea grasses are most common large primary producers on soft bottoms and live only in certain places. Animals that live on soft bottoms also lack solid attachment sites. Soft bottoms stay wet after the tide is out, so the problem of desiccation is not as critical as in the rocky intertidal.]]> 2018-05-01 18:05:32 UTC https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256978631 19reedan https://padlet.com/19vochelliwp/ed954edkiwx2/wish/256978790 Most sediments are made up of a mixture of different particle sizes.
