1 Level 2: Herbivores eat plants and are called primary consumers. 2  Level 3: Carnivores that eat herbivores are called secondary consumers. 3  Level 4: Carnivores that eat other carnivores are called tertiary consumers. 4  Level 5: Apex predators that have no predators are at the top of the food chain.t the lowest trophic level (the bottom of the food chain), plants convert about 1% of the sunlight they receive into chemical energy. It follows from this that the total energy originally present in the incident sunlight that is finally embodied in a tertiary consumer is about 0.001%.
Purple Turquoise is the 'new' Mohave Turquoise which is not all that new and just like Mohave Green Turquoise not a natural color, but a brilliant addition to Jewelry Making specifically for American South West jewelry designs.
Turquoise is rarely found in well-formed crystals. Instead it is usually an aggregate of microcrystals. When the microcrystals are packed closely together, the turquoise has a lower porosity, greater durability, and polishes to a higher luster.he earliest record of turquoise being used in jewelry or in ornaments is from Egypt. There turquoise has been found in royal burials over 6000 years old. About 4000 years ago, miners in Persia produced a blue variety of turquoise with a sky blue or robin's egg blue color.
