What are the biotic parts of an ecosystem?

The biotic factors of an ecosystem include primary producers, herbivores, carnivores, omnivores and detritivores. Primary producers are able to make their own food using chemical energy or energy from the sun. Plants and some types of bacteria are primary producers.\n\nHerbivores are organisms that eat primary producers. Sheep and cows are classified as herbivores. Carnivores and omnivores both eat herbivores. Carnivores are called meat eaters because they eat animals. Omnivores eat both plants and animals.\n\nDetritivores feed off of dead organisms as well as decaying organic matter. Earthwor..

Do non-pathogenic bacteria cause disease?

For example, the human digestive tract contains bacteria that help it function properly. These bacteria not only aid in the digestive process, they also kill pathogenic bacteria. Bacteria are used in the production of certain dairy products, such as cheese, sour cream and yogurt. In the natural world, some bacteria function as decomposers, breaking down dead organisms. Other types of bacteria consume oil, and this natural tendency is most visible during oil spills or leaks.

What does HB in a blood test mean?

Hemoglobin is a very important part of the blood. This protein is found in red blood cells and is responsible for carrying oxygen through the body. Hemoglobin tests are usually included with blood tests.Normal hemoglobin levels vary depending on age and gender. Normal levels for men range between 13.8 to 17.2 grams of hemoglobin per deciliter of blood. Normal levels for women range between 12.1 to 15.1 grams per deciliter of blood. Results for children vary even more. Newborn babies have a normal range of anywhere between 14 and 24 grams per deciliter, whereas older babies have much lower leve..

What are some facts about coastal plains?

Coastal plains can be near an ocean, river or lake and are separated from the interior land by a mountain or hilly range, states OpposingViews.com. The fall line of a coastal plain is the inland boundary where it meets the nearby landform and creates waterfalls or rapids due to eroding sedimentary material. The EPA explains that since the coastal plain areas are either just above or under water, much of these regions are wetlands, which contain important ecosystems for a variety of species. Coastal plains are usually heavily wooded and provide important economic functions to surrounding region..

What is polarized light?

Light is a transverse electromagnetic wave, but natural light is generally unpolarized because all planes of propagation are equally probable, as explained by Georgia State University. There are three types of light polarization: linear, circular and elliptical, all of which are composed of two plane waves differing in phase by 90 degrees. The difference between them has to do with the amplification of the individual waves.

How do polysaccharides form?

Polysaccharides are classified as polymeric carbohydrate structures. They are comprised of dozens, even hundreds, of smaller molecules called mono or disaccharides, which form long chains in the presence of glycosidic bonds. These bonds are comprised primarily of a starchy, viscous substance called glucose, which is a type of sugar converted by the body to produce energy. Glycosidic bonds are resilient and sticky and function much like glue to seal two or more saccharides together. Polysaccharides grow to various sizes; like trees, some are short in length and have few branches, while others h..

How much does a newton weigh?

One newton is the amount of force required to accelerate an object that weighs one kilogram one meter per second each second. The force of Earth's gravity on a person who weighs 70 kilograms is approximately 686 N. The newton is named after the famous physicist Isaac Newton in recognition of his work in establishing his second law of motion, which involves the measurement of net force on an object.

How many watts does a solar panel produce?

There are different views regarding the average wattage of a solar panel. The average wattage among the top 10 manufacturers is around 200 watts, according to Pure Energies. Prospect Solar, on the other hand, finds the average to be around 250 watts.\nFor larger-scale solar power usage, solar panels are often grouped together in arrays. The energy potential of the entire array is the product of an individual panel's output rating and the number panels in the array, creating multiple kilowatts of energy potential if dozens of solar panels are placed together.

How long does high tide last?

High and low tides are the result of the moon's gravitational pull and the Earth's rotation. Two high tides and two low tides occur simultaneously on opposite sides of the Earth due to the gravitational pull caused by the moon and the inertia of the ocean caused by gravitational forces. The gradual receding of water into a low tide is known as the ebb tide, while the gradual rising of the tide is known as the flood tide.

What is the normal phase of platinum?

Live Science notes that platinum has an atomic weight of 195.084 and an atomic number of 78. Platinum, or Pt on the periodic table, has six stable isotopes in nature and three other isotopes created in laboratory conditions, according to About.com Chemistry.\nPlatinum is hammered into different shapes and strung into long wires. The shiny metal resists corrosion and conducts electricity, and it is made into jewelry and electrodes. Bullion.com explains that in order to make 1 ounce of pure platinum bullion, manufacturers need 10 tons of ore and 5 months of purification out of rocks. Platinum or..
