Food Web

1. Subtitle “Marine Food Web”.  Research the marine organism that you played in the food web activity: what eats it and who it eats. Fit the organism into a balanced marine ecosystem. What are the trophic relationships in your design? What would happen to the food web if one species were to become endangered or extinct? Which species would be affected? Which ecosystem would be affected?
1. Write the answers to the above questions as one paragraph.
2. Describe the class activity and record your 1/28 exit ticket.

1a. The food wed in an important part to all organisms. In the ocean every organism in the ocean is very important to one another. One animal eats another animal who eats another animal. Without cretin animals the food chain would slowly start to die. They all need each other for food.

1b. The class activity that we did was a fun activity.I enjoyed it, it really showed how much the food chain is connected and how every organism big and small are important in there own way. The activity showed us that with out some animals other animals would not be able to eat, therefor they would not be able to survive.

1. Subtitle “Phytoplankton”. The second activity you did was to learn about the neuston ecosystem and look at diatoms under the microscope.
   1. Explain why phytoplankton is so important to marine food webs. Identify the organisms that are in the neuston ecosystem, and how much of Earth’s surface this ecosystem covers.
   2. Write up your diatom lab results in a single paragraph. This includes

i.Hypotheses from page 3.

ii.Activity 1 results on page 5.

iii.Conclude and communicate on page 5.

1a. Plankton is important becuase they provide food for almost all the organisms that are living in the ocean. Plankton also take up about 71% of the oceans there are so many of them.

1b. Diatoms are very small organisms, they can only be seen under a microscope

1. Subtitle “Energy Flow”. Describe what happens to the amount of energy/biomass that is transferred from one trophic level to the next.

About 10% of net energy  is produced through the trophic levels. It reduces the energy transferred between the different trophic levels such  as  respiration, growth and reproduction. Death of organism also affect the impact on the energy flow. When animals die off other animals get impacted by them because they need each other to live.

        2.Subtitle “Human Impacts”. Answer and discuss the following:  What roles do humans play in marine food webs? How can human actions upset the balance of an ocean ecosystem?

Human impact effects the ocean in many ways. When we fish of dump things into the ocean it is killing the organisms in it, not all  but some. When we do things to destroy the ocean on purpose or not not matter what it will effect the ocean. When we impact the ocean we are impacting everything that's in it, the organisms that are in it suffer when we do things to put them in harms way.
