What does it do for us? 
-Regulates our climate 
-Provides resources  ]]> 2019-04-30 15:37:49 UTC https://padlet.com/20congermm/n0tvm4dba3x/wish/355491528 20congermm https://padlet.com/20congermm/n0tvm4dba3x/wish/355491718 There is no place for attachment because there is no bottom floor in this zone. It provides support for marine fisheries. Also, nearly all primary production (photosynthesis) occurs within the pelagic zone. ]]> 2019-04-30 15:38:12 UTC https://padlet.com/20congermm/n0tvm4dba3x/wish/355491718 20engleek https://padlet.com/20congermm/n0tvm4dba3x/wish/355493318 Epipelagic Zone:
-Surface of the water to 200 meters deep
-Photic zone, where most light is accessed by plankton and other photosynthetic organisms.]]> 2019-04-30 15:41:19 UTC https://padlet.com/20congermm/n0tvm4dba3x/wish/355493318 20engleek https://padlet.com/20congermm/n0tvm4dba3x/wish/355495047 The main abiotic component in the pelagic zone is the access to sunlight. In addition, there is salinity, currents and waves, and exposure to air.]]> 2019-04-30 15:44:13 UTC https://padlet.com/20congermm/n0tvm4dba3x/wish/355495047 20congermm https://padlet.com/20congermm/n0tvm4dba3x/wish/355498267 Limiting Factors- There is not many places to hide due to how much light there is and how little amounts of hiding places there are.
Competition- The organisms that live here mainly compete for food.
Adaptation- Lots of the organisms, such as sharks, have adapted to blend in with the ocean in a certain way. The bottom of a sharks body is lighter than the top part of it's body.]]> 2019-04-30 15:50:04 UTC https://padlet.com/20congermm/n0tvm4dba3x/wish/355498267 20engleek https://padlet.com/20congermm/n0tvm4dba3x/wish/355498502 Primary producers (photosynthesizers): phytoplankton.
Primary consumers: small fish, squid, crustaceans.
secondary consumers: tuna, dolphins, turtles.
tertiary consumers: sharks, whales, killer whales. ]]> 2019-04-30 15:50:30 UTC https://padlet.com/20congermm/n0tvm4dba3x/wish/355498502 20runnallsct1 https://padlet.com/20congermm/n0tvm4dba3x/wish/355500054 Sharks- They live practically everywhere in the pelagic zone. A sharks diet consists of seal and large fish. Their only predators are humans. Sharks also have great camouflage called counter shading.This means the top of them is dark to match the ground when looked at them from above and their bellies are lighter to blend into the sun when looked up at. Sharks have a symbiotic relationship with remoras as the remoras gets its food from attaching to the shark and the shark gets no benefit. Studies suggest that the remoras actually  clean parasites from the shark's teeth and perhaps skin.

Tuna- travel from kelp paddy to kelp paddy preying on smaller fish like mackerel and sardines. Their predators are larger fish like wahoo, billfish, and sharks. They have adapted their fins to to be "v" shaped for very fast swimming and their bodies to be very streamline for very good hydrodynamics.This is good for not only chasing after prey but escaping predators. They have a symbiotic relationship with dolphins as they alert each other to fisherman and other predators as they swim together.

Jellyfish- The jellyfish has a  transparent body that make it harder for their predators to see them. They also have arms with tentacles that carry stinging cells that can paralyze or stun their prey and predators.  The medusa can shrink in size when food is scarce and grow when it is abundant. They live in the open ocean and drift in the currents and can live in different temperature waters. They  play an important role in the oceanic food chain and the ecosystem. They live off of plankton, small crustaceans, fish eggs, fish and other jelly fish. Turtles, sunfish and spadefish eat jellyfish. It has a symbiotic relation with shrimp and algae. Shrimp live in the tentacles and eat parasites that enter. Algae live on the body of the jellyfish and are responsible or the coloring of some jellyfish.   

Dolphin - The dolphin's adaptations enable a dolphin to conserve oxygen. They are able to slow their heart rate while diving, so blood is shunted away from tissues tolerant of low oxygen levels toward the  heart and brain.  Dolphins maintain the ecosystem, because they prey mainly on old and ill fish. This way they are playing an important role in fighting infectious diseases among fish populations. Sharks and killer whales prey on dolphins. Dolphins live in all oceans of the planet and even in some rivers.  Dolphins help humans by attacking a group of fish forcing the fish to swim towards fisherman, so the dolphins don't get stuck int he nets.  Some fish and dolphins tend to be found together and work together to detect and alert each other of predators so they can avoid these predators.

Sea Otters -  Sea otters have long whiskers that help them detect motion in murky waters. They also have retractable claws that help them hunt and groom and to use as tools. Sea otters tend to live in shallow coastal waters off the northern Pacific. Their predators include killer whales, great white sharks, sea lions and even sometimes eagles. They love to eat sea urchins and and other invertebrates that graze on giant kelp. Without sea otters, these grazing animals can destroy kelp forests and consequently the wide diversity of animals that depend upon kelp habitat for survival. with Kelp. Sea otters have a symbiotic relationship with kelp as they eat the urchin that hurt the kelp. ]]> 2019-04-30 15:53:06 UTC https://padlet.com/20congermm/n0tvm4dba3x/wish/355500054 20engleek https://padlet.com/20congermm/n0tvm4dba3x/wish/355502409 2019-04-30 15:57:20 UTC https://padlet.com/20congermm/n0tvm4dba3x/wish/355502409 20engleek https://padlet.com/20congermm/n0tvm4dba3x/wish/355502556 2019-04-30 15:57:39 UTC https://padlet.com/20congermm/n0tvm4dba3x/wish/355502556 20engleek https://padlet.com/20congermm/n0tvm4dba3x/wish/355504139 2019-04-30 16:00:56 UTC https://padlet.com/20congermm/n0tvm4dba3x/wish/355504139 20engleek https://padlet.com/20congermm/n0tvm4dba3x/wish/355515866 2019-04-30 16:25:54 UTC https://padlet.com/20congermm/n0tvm4dba3x/wish/355515866 20congermm https://padlet.com/20congermm/n0tvm4dba3x/wish/355516078 2019-04-30 16:26:20 UTC https://padlet.com/20congermm/n0tvm4dba3x/wish/355516078 20runnallsct1 https://padlet.com/20congermm/n0tvm4dba3x/wish/355516180 2019-04-30 16:26:33 UTC https://padlet.com/20congermm/n0tvm4dba3x/wish/355516180
