1. Facts about coral reefs : what is coral reefs?
A coral reef is composed of living organisms that have fused together (Image : funscubadiver.com) Have you seen the coral reefs? Maybe some of you ever see the coral reefs through television, magazines, or look directly at the resorts that present the beauty of coral reefs. When viewed in passing, coral reef looks like a bunch of plants because it looks dwelt on the sea floor and waving like a twig in the wind. Do you know what is coral reefs? Coral reefs are a bunch of coral animal symbiosis with plants algae (Zooxanthellae). Symbiosis is a unique relationship between two living beings.
Animals coral shaped like rocks or plants with a wide range of colors and shapes. These animals are called polyps. Polyps including animals that have no spine (Invertebrates). Polyps are still a relative of the jellyfish but its size is very small.
Polyps have a mouth surrounded by tentacles that can sting. This tentacles waving like a twig in the wind. The tentacles contain a poison that is used to catch small animals and plants (plankton) as additional food. While the main meal of the coral animals derived from plants with symbiotic algae. Animals can produce calcium coral reefs become so hard.
Plant algae symbiosis with coral animals called Zooxanthellae. Zooxanthellae size is very small and can not be seen with the naked eye. Zooxanthellae can only be viewed with the aid of a tool called a microscope. The microscope is a useful tool to enlarge the appearance of objects. Objects that are so small as dust, bacteria, fungi, and viruses will become obvious when viewed with a microscope.
Zooxanthellae that live within coral numbered in the thousands. Zooxanthellae have chlorophyll (leaf green substance) that can perform photosynthesis with the help of sunlight. Some of photosynthesis in the form of food and oxygen will be used to meet the needs of coral animals. Instead, Zooxanthellae will get shelter from predators. Zooxanthellae also use carbon dioxide waste products of respiration of coral animals to photosynthetic material. Thus, animal corals and Zooxanthellae have a mutually beneficial relationship. The relationship between two living beings mutually called mutualism.
