Biotic: Fish Invertebrates Molluscs, Crustaceans, and Echinoderms Seagrasses and Algae
Abiotic: Sun Salt Water Sand Calcium limestone
Carrying Capacity: The largest number of individuals of one species that an environment can support.
Algae is affected by water temperature. If the water temperature increases the green algae decreases and causes unhealthy coral. This unhealthy coral turns white and is called the bleaching affect.
Energy Roles: Producers, consumers, and decomposers. Energy flows from the sun to the plants and algae that convert light energy from the sun into chemical energy then it is passed on through the food chain. Plant cells collect energy from the sun and provides food for coral organism to eat. Polyps feed on plankton and the parrot fish feed on the polyps. Parrot fish produce much of the sand on the bottom of the reef. Seacucumber eats the sand and eats the algae. Seaslug eats plants and gets energy from the sun. Longspin Sea Urchin eats algae and is eaten by barracudas.
Food Webs: A variety of animals can eat a species and that is the reason a food web is more realistic than a food chain.
When the population of Long Spine Sea Urchin decreased in the 1980's it caused an increase in algae. This caused the coral reef to become off balance and was dominated by algae loosing and declined in coral cover.
Energy Pyramid: A model that shows how energy flows through a food chain/web
Third level consumers-"tertiary consumers"; carnivores or omnivores
Second level consumers-"secondary consumers"; carnivores or omnivores
First level consumers-"primary consumers"; herbivores or omnivores
Producer- plants, grass, and trees
The energy pyramid needs to be a triangle because it shows how through the process there are fewer predators because they have been eaten.
The things a plant needs for photosynthesis is sunlight, chlorophyll, water, and carbon dioxide. During photosynthesis a plant produces oxygen or O2. Photosynthesis occurs inside plant cells in small things called chloroplasts. Chloroplasts contains chlorophyll which absorbs light to make photosynthesis.
the photosynthesis formula
In the coral reef photosynthesis may occur in corals.
Photosynthesis helps in the coral reef ecosystem because it helps with algae and algae is a very important part and necessary for it to be a healthy ecosystem. Of the two main types of plants found in the coral reef environment algae and seagrasses, and algae is probably the most important to the health of the reef.
the role of decomposers
Decomposers serve an extremely important function in all ecosystems; they break down dead matter and waste products and convert them into usable energy while returning important materials to the environment. The main decomposers in coral reefs are bacteria these bacteria play an important part in the nitrogen cycle whereby ammonia (NH4) is converted into nitrite (NO2) by bacteria in the genus Nitrosomonas after which nitrite is then converted into nitrate (NO3) by bacteria in the genus Nitrobacter.
adaptations are important to have because without them it makes it hard to live in a environment, they need adaptations to do things like hide from predators.
In the coral reefs fish would have to be maneuverable, be able to go in small places, and have bright colors to help with mating or camouflage.
If you put a animal in a different environment it would not be able to use most of its adaptations and it would make it hard to survive, but after generations it would slowly start adapting to the environment.
Natural selection:the process whereby organisms better adapted to their environment tend to survive and produce more offspring. natural selection is important because it basically shows the it is survival of the fittest.
Sea sponges compete with each otherfor space.Over millions of years of turf wars, sponges that evolved anti sponge toxins usually won against one that don't have anti sponge toxins. Now most sponges produce potent toxins.
