What should be done with the contents of
a composter? Explain your reasoning.

Answers

Answer:

Finally, the number of times the pile is turned influences composting speed. By turning more frequently (about every 2-4 weeks), you will produce compost more quickly. Waiting at least two weeks allows the center of the pile to heat up and promotes maximum bacterial activity. The average composter turns the pile every 4-5 weeks.

When turning the compost pile, make sure that materials in the center are brought to the outsides, and that materials from the outside edges are brought to the center.

With frequent turning, compost can be ready in about 3 months, depending on the time of year. In winter, the activity of the bacteria slows, and it is recommended that you stop turning the pile after November to keep heat from escaping the pile's center. In summer, warm temperatures encourage bacterial activity and the composting process is quicker

Using compost in the yard

Incorporate compost into your garden as you prepare the soil in the spring. Cover the area with 3-4 inches of soil and till it in to at least the upper 6 inches of soil. Add compost to soil in vegetable gardens, annual flower beds, and around new perennials as they are planted.

You may also use compost as mulch around flower beds, vegetable gardens, or around trees or shrubs in landscape beds. Apply a 3 inch layer. Be careful not to apply mulch close to the main stem or trunk of the plant.

What are the 6 kingdoms of life? Provide an example for each.

Answers

Answer:

Archaebacteria

Archaebacteria are the most recent addition to the kingdoms of organisms. Their existence was not discovered until the 1980s. However, Archaebacteria are the oldest known living organisms. They are single-celled and thrive in extremely hot boiling water found in environments like volcanic thermal vents in the ocean and hot springs like the geysers at Yellowstone Park. Some species also live in very salty environments such as The Dead Sea and The Great Salt Lake.

Eubacteria

Eubacteria are also single-celled bacterial organisms. This kingdom makes up most of the bacteria in the world. Eubacteria are very common and well-known to us as parasites like Streptococci which causes strep throat. However, these bacteria also help produce many antibiotics, vitamins and yogurt.

Fungi

The Fungi kingdom is recognizable to us as mushrooms, molds, mildews and yeasts. Unlike the organisms in the Archaebacteria and Eubacteria kingdoms, Fungi are multi-celled organisms. Early scientists classified mushrooms and other fungi in the Plant kingdom but they do not produce their own food as plants do.

Protista

Protista or Protozoa are single-celled organisms, but are more complex than single-celled bacteria. The Protista kingdom includes algae and slime molds. Any microscopic organism that does not fall into the bacterial, fungi, plant or animal kingdoms is considered a part of the Protista kingdom.

Plants

The Plant or Plantae kingdom encompasses all flowering plants, mosses and ferns. Plants are multi-celled, complex organisms and are considered Autotrophic. This means that plants create their own food through photosynthesis. The Plant kingdom is thought to be the second largest with over 25,000 known species.

Animals

The largest kingdom of organisms is the Animal or Animalia kingdom. This kingdom is made up of complex, multi-celled organisms ranging from sea sponge colonies to elephants. All organisms in the Animal kingdom are Heterotrophs meaning, unlike plants which produce their own food, animals feed upon other organisms. The Animal kingdom is the world's largest with over one million known species.

How would a biomagnification “pyramid compare with an energy pyramid?

Answers

Answer:

Energy pyramid depicts flow of energy in the ecosystem: source of all energy in ecosystem is the SUN. Producers are only organisms in ecosystem who can trap the solar enrgy. So base of energy pyramid is always wide. A biomass pyramid shows the total dry mass of all living organisms at each trophic level.

Explanation:

Because the amount of the pollutant increases as it goes up the food chain, the biomagnification pyramid is inverted whereas the energy pyramid is consistently upright.

What is biomagnification?

Biomagnification is the amassing of a chemical by an organism as a result of exposure to both food and water, resulting in a concentration that is higher than what would have been expected from equilibrium and higher than what would have occurred with only water exposure.

When dangerous chemicals like DDT that remain in the environment are indirectly absorbed by living things through food, this process is known as biomagnification.

When a higher-order organism consumes a lower-order organism that contains such compounds, the chemicals may accumulate in the higher-order organism.

The biomagnification pyramid is upside down because the amount of the pollutant increases as it moves up the food chain. The energy pyramid, however, is always upright.

Thus, this can be the comparison between the energy pyramid and biomagnification.

An organism that produces offspring identical to the parent when self-fertilized is known as a true-breeding organism. It is also called purebred.

A true-breeding or purebred is a type of organism that always passes specific phenotypic traits to its offspring.

A true-breeding must be homo-zygous (i.e., purebred) to pass certain phenotypic features to offspring.

True breeding organisms are very useful in conventional breeding techniques to pass desirable phenotypic traits to offspring.
