How are decomposers used in the treatment of sewage?

Decay is an essential life process that digests food or waste matter and recycles materials. Materials from living things decay because they are digested (broken down) by microorganisms. These microorganisms cause decay by releasing enzymes that break down compounds to be absorbed by their cells.

Bacteria and fungi are the main groups of decomposer.

Factors affecting decayThe factors that affect the rate of decay include:
  • moisture
  • temperature
  • amount of available oxygen.

Microorganisms are more active and digest materials faster when they are in moist, warm and aerobic conditions. They will digest materials more slowly in dry, cold and anaerobic conditions.

CyclesSome of the substances released during decay are needed by plants for healthy growth. In a stable community of living things, processes that return substances to the environment (such as decay) are balanced by the processes that remove and use substances. In this way, the substances are continuously recycled.

Why is Lake Ontario the most polluted?

The problem with Lake Ontario is mostly its elevation. AS the lowest lying Great Lake, it accumulates the down stream runoff from all the other lakes. Also add to the fact it's location as an old industial waterway (steel mills of Ohio) and its history of pollution has been decades. It's slowly recovering now because those mills are mostly in the southern USA. Today's problem is mostly with Nuclear Power Plants and their warm water. Nuclear Plants usually need a huge volume of cold water to cool their super hot reactors. In the Midwest, most plants are required to hold this superheated water for a few weeks and then release it when cool. That does not happen on the Lake as power companies release warm water, effluent release temperature is dictates as part of plant licensing, following an environmental impact study. The lake also suffers from foreign population as large ocean going ships dump water, usually polluted water from Asian shores (used to balance the ship when empty), into the waterways. Hence how the zebra mussel got there. It's just location, of being the lowest in elevation, heart of the old American industrial heartland, and doorway to the rest of the inner great lakes, makes the Lake a hallway that people wipe their feet at when entering the countries interior.

What is the solution for domestic sewage?

Don't flush your toilet every time you have a wee, the energy to pump and clean the water to flush the toilet causes a lot of C02 Emissions Wee outside when possible don't get caught though in public you can face a criminal charge for exposure just tell the cops you were helping save the environment if they ask you questions. There will be no charge if no one was around to see you.

As for the other sewerage put it in a bucket and use it on your garden and don't tell the neighbours what it is mix it well with your soil. Or collect it in mass amounts and sell it for energy production. Methane and fertiliser for farmers.

What are the pros and cons to Participative leadership?

I really dont the answer for this question, so you please not ask again....thank you

What is the optimal level of pollution?

when marginal benefit is equal to marginal cost

To be more specific:

When the marginal damage cost of polluting is equal to the marginal abatement cost of polluting (or the marginal benefit of polluting, which is equivalent to the MAC)

How do you weigh gases?

All matter has mass. All things with mass weigh something in a gravitational field.

Gases are matter and on Earth are in a gravitational field, so they weigh something.

Sometimes it would seem they are weight free or even buoyant because of the ther gas in the atmosphere. However in isolation with these effects removed they all have weight.

An example of gas weights: Most atmospheric gases weigh around 30 g per 22.4 liters

What is the function of methylene blue solution on polluted water samples?

Polluted water sample will decolorize the methylene blue solution faster than a pure water sample.

What steps are taken by the government to reduce the level of pollution in Pakistan?

Pakistan government has taken defference steps to reduce the polllution level. Inorder to decrease the air pollution government organize tree plantation compaign twice a year.

Particles of radioactive emissions?

Alpha particle - (helium nucleus) with a positive charge Beta particle (high speed electron) with a negative charge Gamma ray (electromagnetic radiation) with no charge Radio active decay occurs because the nucleus is unstable. It depends on the particular atom which decay path it will take. A stable atom normally has a few more neutrons than protons. If there are one or two extra neutrons, but not enough to make it stable, getting rid of two of each will slightly increase the proportion of neutrons making it just a little more stable. In this case ALPHA radiation is the result. This consists of helium nuclei with two protons and two neutrons. If there are too many neutrons, one can turn into a proton. When this happens an electron must come into existence by being ejected from the neutron. This is called BETA radiation. If there are too many protons, one of them can eject a positron (positively charged electron) and turn into a neutron. The positron will then very quickly unite with an electron. When this happens they annihilate each other and become very high energy photon (light particle/wave) called a GAMMA ray. This happens mostly in nuclear reactors or in bombs. An example of beta (electron emission) radiation is when Radium 225 loses an electron and turns into Actinium 225 (half life 14.8 days). An example of alpha radiation is when the resulting Actinium loses a helium nuclei or alpha particle to become Francium 221. (half life 10 days) During these processes, other particle called neutrinos are also formed just as they are in the sun. For more about particles check related links below

What are harmful effects on ecosystem?

Harmful Effects on the Ecosystem: Pollution of LandImproper disposal of waste from homes, offices, hospitals, stores and factories causes garbage to pile up. Open dump sites destroy the beuty of a place. They also provide breeding places for rats and flies, which are harmful to people. Topsoil is an important part of the land, When farmers use too much inorganic fertilizers, the soil loses some of its nutrients that are needed by plants. This is because the fertilizers limit the ability of decomposers to break down waste in soil. Pesticides sprayed on plants do not decompose easily. They may kill people and animals who eat the plants. Mining operations contaminate the soil with poison from metals. When land is polluted, the nutrient cycle may be disrupted. Pollution of Water Pollution of water is harmful to plant and animal life. Take for example, life in a pond ecosystem. Here, algae are the food producers. Some fish eat algae. Some big fish eat smaller fish. Life in the pond can be disrupted. Many people use detergents for washing clothes. When laundry water is drained into a pond, the water becomes polluted. The polluted water contains phosphorus and nitrogen which are nutrients needed by plants in making food. The plants in the pond will grow fast until they cover the whole pond. When the nutrients are all used up, the plants will die. As decomposers feed on dead plants, they use up much oxygen in the water, so the fish has less oxygen to use. When the oxygen in the water is used up, the fish will die. Eventually, the pond will also die. Sewage water may contaminatedrinking water supplies. Contaminated water can make people and animals sick. Leachate is liquid runoff from dumpsites that seeps into the groundwater. Leachate may have contaminants such as lead. Pollution of Air Greenhouse Effect Burning of fuels releases more carbon dioxide into the air than the forests can recycle. Too much carbon dioside in air traps heat which otherwise should escape to space. When heat cannot escape, air becomes warm. The rising temperatures can cause a change in climates. When the climate becomes warm, the ice caps in the polar regions would melt and cause flooding of coastal communities in many countries. Acid Rain The gases released by some industries and motor vehicles contain chemicals that make rainwater acidis (sour). Acid rain can kill plants and animals on land. It can also kill plants and animals in water. Acid rain can also damage buildings and statues.

How do you prevent birdseed from germinating?

Bird seed that comes in a bag won't germinate unless you plant it and it grows. Or it falls into my flower beds and sprouts all over the place.

Is every country overpopulated with animals?

No, actually in about every country there is a endangered species.

How long does it take plastic and aluminum cans to break down?

It takes approxmatly 500 to 1000 years for plastic and aluminum to break down.

Is acid rain covered under your auto policy?

Policies vary so you will meed to check with your agency. Though, acid rain most likely is not covered, it could b considered damaging to your vehicle, so there is always a slight chance it is covered. Again, you should ask your agency.
