2).Biotic and Abiotic factors

Abiotic factors-sand,dirt,oil,plastic,trash,rocks,water.

Biotic factors-sharks,seaweed,dolphins,seals,fish,whales.

3Carrying Capacity

Carrying capacity is the largest number of individuals of one species that a environment can hold.

In the ocean it needs plants,sand,water and most of all animals, the ocean needs animals so when they eat each other the ocean can get nutriments from the left overs.

4).Limiting Factors

The limiting factors in the ocean could affect every animal, Like if seals become extinct than great white sharks population would start to decrease and the producers would increase.

5).Energy roles

Energy roles in the ocean- algae-->shrimp-->seals-->sharks

6).Food chains & Food webs

Food webs bring all the food chains together in the ecosystem.

Food chains show a direct relationship.

If you remove a population for example producers, than the 2nd level consumer cant eat ,then the 3rd level cant eat ,then the 4th level cant eat, and the whole ecosystem will die.

7).Trophic pyramids and Energy pyramids

The reason why the energy pyramid is a triangle is because first its a pyramid shape, second is the base is the largest in the energy pyramid and on a triangle the base is the largest.

The reason that producers are the largest on the energy pyramid is because it gets all of its energy from the sun, and it has to produce food to give other animals.

8). Photosynthesis

Chemical equation= 6CO2 + 6H2O----> C6H12O6 + 6O2.

For Photosynthesis to occur, plants need sunlight, water, carbon dioxide and chlorophyll.

Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts contain a green substance called chlorophyll. This absorbs the light energy needed to make photosynthesis happen.Plants can only photosynthesise in the light.

Light energy from the sun is being converted to chemical energy(which is stored energy). Photosynthesis is a chemical process that takes place in the presence of sunlight, wherein plants make their food and build stores of energy. This phenomenon occurs in chlorophyll containing plant cells.

9). Tropisms

Tropisms in ocean- Seaweed, Plants.

Seaweed helps the ecosystem survive because when fish eat the plants and it decays and nutrients go into the soil and makes the soil stronger.

10). The role of Decomposers

If their were no decomposers in the ocean the soil would be weak and there would not be any small fish that other animals could eat and they would all die.

Decomposers in ocean- Algae, Plankton, Small fish.

"Tropisms in ocean- Seaweed, Plants." These aren't tropisms... they are examples of organisms. "Seaweed helps the ecosystem survive because when fish eat the plants and it decays and nutrients go into the soil and makes the soil stronger."-- what does this have to do with tropisms? You need to go back through the instructions; you are missing a lot of information that is asked for in the instructions.
