coral reef limiting factors and predator prey

limiting factors:



sharks eat many coral reef fish and if something else started eating the fish this factor would be limited and the sharks would start dying out faster

energy roles

producer :

sea weed is a producer that is eaten by herbivore fish

consumer: herbivore fish

the producers have the largest base bc every food chain or web begin with plants . it is shaped like a pyramid, because the energy transformation is decreasing by 10%.


geotropism in my ecosystem helps the seaweed grow upwards. the seaweed is a source of food and shelter for some animals. this tropism helps so that the seaweed grows upward but it could also be an example of phototrophism.


decomposers are vital to my ecosystem because if there were none the all the dead stuff would start to pile up on the ocean floor.

some decomposers are small bottom feeding fish, sea snails,plankton,krill

I think you skipped the carrying capacity section. Make sure to revisit the instructions to double check that you are including everything that is required.
