Help needed this is due tomorrow. i need the paragraph
Write a paragraph that explains the flow of energy and matter through the food web. Include the role of the sun, producers, consumers, and decomposers.
Assignment:
On the right is a picture of an aquatic
ecosystem. A scientist was observing the
animals that live in this ecosystem. She took
field notes that are shown below.
Please use the biologistβs field notes to create
a food web showing the flow of energy in this
aquatic ecosystem.

Field Notes
Picture Organism Observations and Notes
Phytoplankton
β Producers that receive their energy from the Sun
β Most are too small to be seen with the naked eye
β When high numbers are present water may look green due to the
chlorophyll contained in the phytoplankton
β Obtain mass from carbon dioxide dissolved in the ocean
Crustacean
(Copepod)
β Have an exoskeleton (hard shell on the outside of its body)
β Most are between 1 and 2 mm long
β Feeds on single cells of Phytoplankton
β Exoskeleton is so thin that you can see through it and observe the inner
organs
Crustacean
(Amphipod)
β Has an exoskeleton (hard shell on the outside of its body)
β Body is made of segments
β Many different kinds
β Most were less than 10 mm long
β Feeds on Phytoplankton and dead animals or plants
Crustacean
(Krill)
β Feeds on producers filtered from the water
β Used as bait for Opah, Squid and Whale Sharks
β Has an exoskeleton (hard shell on the outside of its body)
β Exoskeleton is transparent and made of calcium carbonate
Whale Shark
β Largest living non-mammal vertebrate
β Feeds by filtering Krill and Amphipods from the water
β Breeding or birth of sharks has never been observed
β Approaches research divers but does not harm them
Flying Fish
β Escapes predators such as the Mahi Mahi, and Albatross by leaping out
of the water and gliding down to a new spot
β Glides are usually close to 50 meters
β Consumers receiving energy from Amphipods & Copepods
β Often found ensnared in the Man-O-War Jellyβs tentacles
Picture Organism Observations and Notes
Squid
β Only a few of these organisms were spotted due to their ability to
change color and become camouflaged
β Moves by squirting a jet of water from its body
β Eats crustaceans such as krill and copepods
Anchovy
β Swim in large schools
β Feeds on Crustaceans (Copepods)
β Frequently found ensnared in the Man-O-War Jellyβs tentacles
Opah
β Sometimes called Moonfish
β Fins are bright red, body is orange on top, pink on the bottom
β Feeds on Squid and Crustaceans (Krill)
β Preyed on by Marlin
Mahi Mahi
β Another name for it is the Dorado
β Gold and blue colored scales
β Commonly found next to floating brown algae
β Feeds on Squid and Flying Fish
Sunfish
β Appears to have only βhalfβ a body
β Observed being βcleanedβ by smaller fish
β Food source appears to be Man-O-War Jellies and Man-O-War Slugs
β Observed warming itself on the surface of the ocean
Man-o-War Jelly
β Floats on the surface of the ocean using an inflated air bladder
β Many long tentacles dangle underneath the jelly
β Captures Flying fish and Anchovy by paralyzing them with stinging
tentacles
β Preyed on by Man-O-War Slugs, Sunfish and Loggerhead Turtles
Loggerhead Turtle
β Average size is 300 pounds and 90 cm long
β Can live to be between 47 and 67 years old
β Considered an endangered species
β Can stay underwater for up to 4 hours
β Plastic and fishing lines cause survival problems
β Feeds on Man-O-War Slugs and Man-O-War Jellies
Man-o-War Slug
β Preyed on by Loggerhead Turtles and Sunfish
β Feeds on the Man-O-War Jelly and uses its stinging cells for protection
β Swims upside down on the surface of the ocean
β Gas filled sac in the stomach allows it to float on the surface
Picture Organism Observations and Notes
Albatross
β Large birds soaring on air currents above the ocean
β Seen scavenging on dead fish and chum thrown from fishing boats
β Observed feeding on squid and flying fish
β Dissection of a dead bird revealed plastic and fishing hook attached to a
line in the gizzard of the bird
Marlin
β Can swim up at speeds up to 50 miles per hour
β Uses rostrum to slash at schools of fish
β Often migrate long distances in search of food
β Receives energy from small fish, Mahi Mahi and Opah
β Only predator is the Mako Shark
Mako Shark
β Fishermen donated a specimen caught in a fishing net
β Weight: 200 pounds
β Length: 10 feet
β Stomach contents: Sunfish, Albatross, Marlin, and Loggerhead Turtles
Sun
β Provides Energy for the Earth
β 109 times larger than Earth
β A star in the middle of our solar system
β Sunrise is observed at different times each day
β Drives Earthβs weather and climate
