This was my first time visiting the aquarium in Boston, and I had a good time and learned a lot. I actually found myself interested by the animals in the tanks and I found myself studying the animals in their habitats more than I was expecting.
I am amazed with the amount of water must have been in the Pacific Community Reef tank. along with that there were so many fish in that tank. I'm upset that there were no sharks still in the tank despite that fact that it said there were sharks still in there. A saw a few huge fish, and the biggest turtle was easily the same size me.
I thought the petting area was really cool. I kind of have a fear about that stuff. I was there with John and he went up and just started touching the rays and I was nervous to do it. I was surprised that they were slippery. I was expecting a hard surface, but it almost felt soft as if it was felt. I guess this is natural protection against enemies because other animals couldn't grab them very well.

Everything I Never Wanted To Know About Seaweed But Had To Learn Anyway
Seaweed is basically grass that grows in the ocean. There are many different kinds of seaweed, the most common is kelp. Seaweed produces between 70 and 80% of the oxygen in the atmosphere.
Photosynthesis Lab
Photosynthesis is the process of transferring light into
nutrients. The chemical equation is 2n
CO2 + 2n DH2 + photons → 2(CH2O)n + 2n DO. In this experiment we took sprigs of
spruce and submersed them in to water. We then put baking soda and placed this under
the light. We then watched the test tube for signs of photosynthesis. The water
began to bubble and this showed photosynthesis.We then added phenol red to the
test tube and covered it with tinfoil. Then we inserted a straw and blew into
the straw and the solution turned yellow because of the carbon dioxide in the
oxygen. When it is left int the dark it changed back to red.

Plankton Decline Due to Ocean Warming
Since the beginning of the 20th century, phytoplankton amounts have been decreasing due to the ocean warming up every year.
Phytoplankton are measured by using satellites that look for heat in the ocean. From recent images in the last years, scientists have determined that the population of phytoplankton are decreasing 1% a year.
Phytoplankton are producers, using the sunlight for photosynthesis, which produces oxygen. With these organisms on the decline less and less oxygen is going to be produced and more CO2 will be introduced into the environment. Since CO2 traps heat the planet will become even hotter, resulting in the decline of phytoplankton at an even faster rate.

Relationships Among Marine Organisms
Marine Food Web
In our food web demonstration I was a protozoan. Protozoa are single-celled eukaryotes (organisms whose cells have nuclei) that commonly show characteristics usually associated with animals, most notably mobility and heterotrophy. They eat phytoplankton and bacteria, the only things smaller than them. They are eaten by small fish and shrimp. Protozoan are in the second row of the food chain so they have 10% of the original energy. Without protozoan in the food web, some animals who would rely on them to survive would die out. When one spot on the food web is taken out, it affects everything else.
Phytoplankton
The phytoplankton are so important because they are the bottom of the food chain. All of the energy in the food chain comes from these. Without them, the whole food chain would disappear because
Energy Flow
The amount of energy transferred to the next trophic level is continually decreasing. Every trophic level only passes on 10% of the energy they have to the next level. The phytoplankton have 100% energy, but when a protozoan eat them, they only have 10% energy. IF eaten by a small fish, that fish only has 1% of the original energy.
