photo credit Nasa / Goddard Space Flight Center / Reto Stöckli By: Michelle Hofbauer & Audrey Hopkins Coral Reef Location Tropical oceans near the equator Climate: Producers Algae, phytoplankton, sea plants
Get energy from photosynthesis
Fish, whales, turtles, eels eat these
They survive because of the sun
Primary Consumers: Secondary Consumers Puffer fish, barnacles, whale sharks
Found all over oceans
Eat primary consumers
Survive by energy provided by primary consumers Sources: http://oceanworld.tamu.edu/students/coral/images/coral_reef_1.jpg Coral Reefs are usually found in tropical waters
(near the Tropic of Cancer).
The water temperature in coral reef areas usually ranges in the 70s and 80sºF all parts of the year. http://www.coral.org/node/126 Examples: zooplankton, coral polyps, sponges, mollusks, sea urchins and smaller fish.

These herbivores are commonly browsers or filter feeders that eat primary producers, found in the second trophic level. ttp://www.ehow.com/about_5523723_trophic-levels-coral-reefs.html#ixzz2E7pBBSuG Zooplankton: Sponges Sea Urchins Decomposers Decomposers break down dead biological matter and waste products and convert them into usable energy
& return important materials to the environment. Decomposers are particularly important in coral reef environments considering the heavy bio-load.
The main decomposer in the coral reefs are bacteria.
Detrivores, or scavengers, play a similar role in recycling dead or waste material;
sea cucumbers and some species of snails, crabs and bristle worms consume dead organisms and/or decaying plant and animal matter Bacteria Sea Cucumbers Bristle Worms Tropic Pyramid Biomass Pyramid Coral reefs rely on both biotic and abiotic factors to keep them healthy and functional. Without stable temperature, pH, light/dark cycles, water flow, salinity, and chemical composition of sea water, coral reefs could not exist.
Without a stable trophic cascade, coral reefs could not survive. Trophic structure in any environment refers to the different levels of the food chain and illustrates the transfer of energy from one level to the next in the form of a pyramid; energy is always lost as it travels “up” the food chain. Discussion Questions 1. How does global warming specifically impact the coral reefs?


2. How do humans impact coral reefs? Answers: 1. coral reefs are among those environments most threatened by global warming. An increase in sea surface temperatures, rising sea levels, and more frequent and severe storms are some of the effects of climate change that can negatively impact coral reefs. These negative impacts ultimately lead to declines in biodiversity. 2. The top concern for the coral reefs is the condition and quality of the water that the coral is growing in. When humans pollute the water, there is great danger for the coral. They could have coral bleaching, which is when large areas of coral turn white. The polyps let out microscopic algae from the cells in their bodies. It then shows the white limestone skeletons that the polyps have. Coral bleaching happens when the are under stress. Algae is what they eat, and without it they don’t get enough food. This leads to the point where the polyps can’t grow or reproduce. Algae Plankton Sea plants Puffer fish Barnacles Whale shark Interesting facts Temperature is 70-85 degrees

The Great Barrier reef in Australia is 1,200 miles and you can see the coral reef from space

Reefs need calcium from water to grow

Coral reefs are important because they remove and recycle carbon dioxide, a gas that contributes to global warming Vocab words The autotrophs in this biome are algae, zooplankton, sea plants. The heterotrophs are zooplankton, coral polyps, sponges, mollusks, sea urchins and smaller fish. The detritivores include some small fish or snails. The herbivores are the heterotrophs. The omnivores are the organisms that get their energy from plant and animal material. The carnivores are sharks, fish, and octopus. In an ecosystem there are a lot of organisms, living and non-living, in an area. In the community of a coral reef there are multiple organisms in one area. Lastly, in coral reefs all of the individuals of a species that live in the same area are called a population. http://www.enchantedlearning.com/biomes/coralreef/coralreef.shtml
