Organ Systems Project (Digestive‚ Excretory‚ Circulatory‚ Reproductive‚ Nervous) There is an enormous variety of life on our planet Earth ranging from simple cell bacteria to complex multicellular animals. Animals are creatures in the kingdom Animilia‚ one of the kingdoms in Whitakers 5 kingdom system. Their bodies consist of 555tanimal eukaryotic cells. Meaning their cell or cells contain a nucleus‚ are surrounded by a cell membrane (phospholipid bilayer) and can self-reproduce in a free

What are Coral Reefs? Coral reefs are reefs consisted of coral consolidated into limestone. They are made of thin layers of calcium carbonate. Stony corals‚ or scleractinians‚ are the corals primarily responsible for laying the foundations of‚ and building up‚ reef structures. Immense reef structures are formed when each individual stony coral organism‚ or polyp‚ secretes a skeleton of calcium carbonate. How are corals classified? Corals are classified as animals although they may resemble plants

Individual slugs will change colors with alterations in food consumption‚ light exposure‚ and moisture levels. Color may also indicate whether a slug is healthy or injured or what age it is.[4] The Pacific

The coral reef and desert ecosystem can be very similar or very different.The difference between the biotic and abiotic factors in the coral reef and the desert the ones in the coral reef live under water ‚and in the desert none of them live under water only some of the fish do. Some of the biotic animals in the coral reef are dolphins and seals. bivalves‚ gastropods‚ tunicates‚ sponges‚ polychaete and feather

Mastigias papua‚ most commonly known as the “Golden Medusa” or “lagoon jelly” is one of the many jellyfishes in the class Scyphozoa. This species of jellyfish is unique because they can be found in bays‚ lagoons‚ and harbors‚ but are most commonly found in the South Pacific and Indian Ocean.

Since this type of jellyfish has very little muscular movement by itself‚ it must be carried

The sea otter is a keystone species. A keystone species is “a species on which other species in an ecosystem largely depend‚ such that if it were removed the ecosystem
