A Number of years ago some chemicals e.g DDT was used on farms to kill insect pests. What are these chemicals why they cause a problem for consumers higher up the food web?

There have been a number of these situations with chemcals other than just DDT. DDT presented a particular problem because it does not leave the ecosystem; it is passed up the food chain. More recently, DDT was discovered on the grounds of the old prison farms at Southern Michigan Prison in Jackson. The Detroit Free Press reported in the mid-80's that surplus Agent Orange was buried on the grounds of G. Robert Cotton Correctional Facility (beneath the dining facility and within feet of one of three well heads there that incidentally suuplies municipal water to the city of Jackson). And, PCBs were buried along with contaminated cattle carcasses on and near the grounds of Pine River and Mid-Michigan Correctional Facilities at St. Louis, Michigan.

Are consumers organisms that get solar or other energy indirectly?
Consumers are heterotrophs and do not get their energy directly, but by eating organisms that do, or by eating other consumers. Herbivores are primary consumers, predators are secondary or higher. Detrivores consume the dead matter left by either producers, or consumers, or both.
Can tertiary consumers be eaten?
If you mean are they the top predators, then No (as they can be scavengers).
What does the hardness of an alto saxophone reed do?
The number on the reed indicates the thickness of the reed. A thinner reed is easier to blow, but also is more delicate and does not last as long. Most beginners start with a lower number reed and, as their "chops" develop, move up to a higher number. Higher numbered reeds also improve quality of sound. It is most common to see a professional using a 2 1/2 - 3 saxophone reed.
What does the fourth to twelfth fret of guitar be used for?
The fourth and the twelfth fret on a guitar are used for the same reasons that the other frets are used to make notes. The higher the number of the fret the higher the note is. Each fret represents a half step up from the previous note.
Why must primary consumers eat large numbers of plants?
Energy concentrations in plants are lower than in animal flesh. Herbivores have to consume large quantities of plant matter in order to subsist. Carnivores, who consume the herbivores, require much smaller volumes of their food source because its energy concentration is much higher.
What happens to the number of organisms as you move from the bottom of an energy pyramid to the top?
The number of higher-level consumers (higher in the pyramid) usually decreases, as they typically consume more than one prey.
Why did DDT become a problem for consumers higher up the food chain?
because they didnt get any or enought food levaing them a high chance to become extinced
What is the effect of environmental protection?
higher prices for consumers
What eats an consumer?
Consumers higher up on the food chain.
Which are the consumers in the food chain?
depends but they are always higher than producers
What effect can consumers behavior have on you?
You will pay higher prices on goods and services.
One drawback to consumers protection regulations is that they lead to what?
higher prices
Are consumers organisms that get solar or other energy indirectly?
Consumers are heterotrophs and do not get their energy directly, but by eating organisms that do, or by eating other consumers. Herbivores are primary consumers, predators are secondary or higher. Detrivores consume the dead matter left by either producers, or consumers, or both.
How will consumers to the incentive of a higher price on a good service?
The negative incentive will cause consumers to purchase less of a good or service if it is of lower quality
What is bioamplification?
Bioamplification, or biomagnification, is the process that results in the increasing toxin concentration in consumers in successive trophic levels. In other words, the collecting of poison and chemicals in animal's tissues becomes more concentrated when animals are higher up in the food chain.
What other actions by consumers can result in higher prices for the things you buy?
Gf
Why higher inflation in US is not a problem?
Higher inflation in the US is not a problem because its citizen consume and invest more when they expect higher inflation.
