Organisms of the Marine Ecosystem
Coral and coral reefs
Symbiotic Relationship- Mutualism
Three limiting factors of the marine ecosystem include:
2. living space
Density-dependent and Density-independent Factors
Here are the organisms in the picture above (in the same format).
Tertiary Consumers - Shark
Secondary Consumers - small fish, whale
Primary Consumers - lobster, shrimp
Producers - algae, plankton, seaweed, kelp
Explanation of the Energy Levels
The energy levels, as shown in the picture above, show how energy is transferred throughout the pyramid. The producers start out with all of the energy, which they receive from the sun. 90% of that energy is used for things such as photosynthesis. The other 10% of that energy is passed on to the consumer that eats it. The primary consumer then has 10% of the original energy. It uses 90% of it to hunt for food and reproduce. It then passes on 10% of its energy to the secondary consumers. The pattern continues throughout the pyramid. This is known as the "10% rule".
