This is an example of secondary succession.
We know that before the presence of charred rocks, an ecosystem did exist before and that's why its an example of secondary succession.
Answer:
Phytoplanktons are single celled organisms found in aquatic ecosystems. They make their own food by capturing sunlight for photosynthesis. Example of some phytoplanktons are diatoms, dinoflagellates and cynobacteria ( blue green algae). Phytoplanktons functions as the primary producers of the aquatic ecosystem. They attain the bottom level in the energy pyramid and store certain amount of suns energy and convert it into food. The energy derive from food is transferred to higher energy levels in the energy pyramid as phytoplanktons are eaten up by many aquatic animals. Therefore, the energy transferred from phytoplankton to higher energy levels gets decreased according to 10% law which says, energy decreases 10% at each higher trophic level. So, all the energy stored by the phytoplankton will not reach the top level of the pyramid.
Atorvastatin calcium (brand name: Lipitor) is a medicine in a class of drugs called HMG CoA reductase inhibitors, also referred to as "statins."
Atorvastatin is used to treat high cholesterol, and to lower the risk of stroke, heart attack, or other heart complications in people with type 2 diabetes, coronary heart disease, or other risk factors
What is Atorvastatin calcium ?
- Atorvastatin is used together with diet to lower blood levels of "bad" cholesterol (low-density lipoprotein, or LDL), to increase levels of "good" cholesterol (high-density lipoprotein, or HDL), and to lower triglycerides (a type of fat in the blood).
- Atorvastatin works by reducing your "bad" cholesterol (low density lipoprotein, or LDL cholesterol) and triglycerides in the blood, while increasing levels of “good" cholesterol (high density lipoprotein, or HDL cholesterol). It can lower the build-up of cholesterol plaque in your blood vessels and arteries that could lead to a heart attack.
- Atorvastatin is an oral tablet you take by mouth once a day to help lower your cholesterol. It is a prescription drug and comes as a generic and brand name (Lipitor) product. Both products come in strengths of 10 mg, 20 mg, 40 mg, and 80 mg.
