What happens when a pesticide is added to a food chain?
When a pesticide is added to a food chain, it can disrupt the balance of the ecosystem by affecting non-target organisms, including beneficial insects and wildlife. As the pesticide is absorbed and accumulated through the food chain, it can lead to bioaccumulation and biomagnification, where higher concentrations of the chemical are found in predators at the top of the food chain. This can result in harmful effects on animal health, reproductive issues, and even population declines. Additionally, the pesticide can contaminate soil and water sources, further impacting biodiversity and ecosystem health.
What happens to contaminants and environmental pollution as you move up the ecological pyramid?
As you move up the ecological pyramid, contaminants and environmental pollutants tend to accumulate through a process known as biomagnification. Organisms at higher trophic levels, such as predators, consume multiple prey that may contain these pollutants, leading to higher concentrations in their bodies. This results in greater toxicity and potential harm to top predators, including humans. Consequently, the effects of pollution are often more pronounced at higher levels of the ecological pyramid.
What happens to the energy that is not passed through the trophic levels of an energy pyramid?
It used by the organisms at each trophic level to keep themselves alive.
The length of time it takes a pesticide to pass through a material to reach the skin is called what?
The length of time it takes a pesticide to pass through a material to reach the skin is called the "penetration time."
What happens to animal cells when they are put into really salty water?
The cells will lose water through diffusion to the salty medium until the concentrations of sodium in the cell is equal to the concentration in the medium
How did the rectangular pyramid get its name?
The rectangular pyramid got its name through its base, a rectangle.
If pesticide from a farm runs off into Lake Michigan which organism in the lakes food chain would test highest for the pesticide?
In Lake Michigan's food chain, the organism that would likely test highest for the pesticide is the top predator, such as a large fish like a lake trout or a northern pike. This phenomenon, known as biomagnification, occurs because these predators accumulate higher concentrations of pesticides through their diet, consuming smaller fish and organisms that have already absorbed the toxins from the environment. As a result, the concentration of pesticides increases at each trophic level, leading to higher readings in top-level predators.
How does a species of mosquitoes adapted to having pesticides in their ecosystem?
Mosquitoes can adapt to pesticides through several mechanisms such as developing resistance through genetic mutations, detoxifying enzymes, or behavioral changes like avoiding treated areas. Over time, these adaptations can lead to a population of mosquitoes that are less affected by the pesticides, making it harder to control them.
How are concentrations in solutions quantified?
through molarity,molality, normality. through molarity,molality, normality.
What are the release dates for Through the Magic Pyramid - 1981 TV?
Through the Magic Pyramid - 1981 TV was released on: USA: 6 December 1981
What evidence is there that the pesticide killed aphids?
Evidence that a pesticide has killed aphids can include a significant reduction in aphid populations observed through counts before and after pesticide application. Additionally, symptoms of aphid mortality, such as the presence of dead aphids or their absence from treated plants, can be documented. Laboratory tests showing the pesticide's efficacy against aphids, along with field trials demonstrating improved plant health and yield, also support the conclusion that the pesticide was effective in controlling aphid populations.
What happens to biomas as you move up the biomas pyramid?
As you move up the biomass pyramid, the amount of biomass decreases because energy is lost as you move up trophic levels through energy transfer from one organism to another. This is due to the inefficiency of energy transfer as organisms consume one another.
