Coral Reefs

Coral Reefs

Producers: Zooxanthellae, calcareous algae, algal mats, phytoplankton, and epiphytes.

Consumers: Corals, clams, sea urchins, crustaceans, brittle-stars, gastropods, grazing fish, butterfly fish, star fish, parrot fish, eels, octopus, and barracudas.

Predators: Sharks, surgeon fish, and manta rays

Threats:

- Pollution

- Global warming

- Habitat fragmentation

- Ozone depletion

- Invasive species (people taking to captivity for aquariums, etc).

- Deforestation (penetration of light may be decreased to the corals).

Climate:

- Average water temperature= 74-84 degrees Feirenheit (cannot live in temperatures colder than 18 degrees celcius).

- Average water salinity= 30-40 ppt (parts per thousand).

- The currents are strong.

Limiting Factors:

- Light intensity

- Salinity

- Temperature

- Water Depth

- Low nutrient (nitrogen)

Resource: Coral calcium

Tropical Rainforest

Producers: cyanobacteria, algae, fruit trees, rubber trees, shrubs, vines, ferns, orchids, etc.

Consumers: Colobus monkey, sloth, humming birds, bees, wasps, lemurs, pygmy, opossum, grasshoppers, slugs, and marmosets.

Predators: Jaguar, anteater, spiders, scorpions, loris, snakes, tigers, golden lion, vampire bats, acacia ant, toco toucan, sumatran rhinoceros, flavus, parrots, and parakeets.

Climate:

- Average temperature

* Day= 30-35 degrees celcius

* Night= 20-25 degrees celcius

- Average rainfall= 1,500-2,500mm/ 250-450cm a year.

Limiting Factors:

- Food

- Sunlight

- Water

- Space

Threats:

- Deforestation

- Habitat fragmentation

- Acid
