Wetland Reflection

Working on this project wasn't a huge struggle for me, but there was one complication I faced. When I printed my pamphlet the inside ended up printing upside down. Aside from that it was rather easy to set up and fill in. I found all my information online through multiple wetland and nature sites. I was a little behind on this project, but eventually I got everything completed. Working on this project I learned that wetlands are a lot more important than most people know they are.

Geologic - Biologic Time Line

The learning activity done for this project was making a biological time line. This activity helped us learn about prehistoric times, plants, and animals. I learned a lot about times and animals i didn't even know existed. for example, my time period was the carboniferous period. My contribution was helping with the fossil, writing the 150 word essay, and finding a silhouette to draw. I learned a lot about other time periods, and animals from the other kids in the class. Devin and I worked well together and got all our work done on time.

Declining Phytoplankton are Effecting the Earth

Out of all three articles i read I believe that "NASA Satellites Underestimating Southern Ocean Phytoplankton by Half, Algorithm Finds." has the least biased opinion because studies have been done to prove what is being stated. Therefore it is not an opinion, but facts. The story being told in 2010 is that the decrease in phytoplankton are having a negative affect on our world. The same story is being told in 2013, except more studies have been done recently. The concern throughout all the articles is that more and more phytoplankton die every year, and it's effecting our planet in a negative way. Phytokankton populations are measured by satellites. The decrease in phytoplankton affects us because they cover a large amount of the earth, and use carbon dioxide as food supply. They also supply the food chain, so if they die out completely so will we. I think it's terrible that they're dying more and more every year, but from the looks of these articles it seems there is nothing we can do to stop it, because it's been happening for years, it's not just recent.

Relationships Among Marine Organisms

Marine Food Web

In the marine food web i was phytoplankton:
All phytoplankton photosynthesize, but some get additional energy by consuming other organisms. They feed everything from microscopic, animal-like zooplankton to multi-ton whales. Small fish and invertebrates also graze on the plant-like organisms. If one member of the food web were to become endangered or extinct the entire food web would slowly fall apart. All animals slowly, but surely, would be affected. Phytoplankton feeds copepods, anchovies, and krill directly. Without phytoplankton the food web would slowly dwindle away.

Phytoplankton

Phytoplankton are the beginning of the food web for most of the planet, they provide nearly half the oxygen to our atmosphere through photosynthesis, and are the main food source for most of the small animals in the ocean. The neuston ecosystem is organisms that float on top of the water, or right below it's surface. This layer cover's about 71% of the earth's surface.
Diatomaceous earth is made up of phytoplankton. What causes the reflection of the sunlight off the diatoms is the shape of the diatom itself and the minerals that make it up. The shells of the diatoms make it useful for reflective paint. they would also be useful for abrasive toothpaste and natural pesticide.

Energy Flow

Energy in trophic levels decreases as it moves up levels because energy is lost. A food chain can usually withstand no more than 6 level transfers before all the energy is used up.

Human Impacts

Humans have a big impact on the marine ecosystem. We are constantly fishing, dumping waste, and playing in the ocean lakes and ponds. Our increase in population has increased our pollution.
