It becomes more concentrated as it accumulates higher up the food chain, predatory species eating herbivorous species end up with deposits in their tissues of dangerously toxic levels. Fish are a prime example, as humans routinely eat predatory fish species (tuna, mackerel, cod, salmon, etc.) which have absorbed the DDT and PCBs (and heavy metals like Mercury) accumulated in the bait species they feed on. The long life span of these species means over time the levels become dangerous. Fish in many places are now considered dangerous to eat regularly (e.g. salmon from Lake Michigan).
What else can I help you with?
What pyramid represents the amount of energy or matter that exists in each level of a food chain?
a food web
The amount of energy that is transferred at each level of the food chain is about?
It depends on the activity of the animal in question but it is usually around 10%.
What happens to the amount of energy available to each successive trophic level in a food chain?
It decreases because there are less and less animals as you go up.
What is a Chart that shows the amount of energy that moves from one level to another in a food chain?
It isn't really a chart. But a pyramid would show the decreasing amount of energy available to those organisms in each level to live, grow and reproduce.
What is a pyramid of mass?
a pyramid of mass is the amount of matters with in a substance and it contain about two of the previous level of a foodchain.A pyramid of mass represents the weight of food that is living in each level of a food chain
Loss of energy in the food chain limits the amount of what?
Loss of energy in the food chain limits the amount of energy available to higher trophic levels, such as apex predators, resulting in a decrease in biomass at each successive trophic level. This loss of energy ultimately constrains the overall biomass and productivity of an ecosystem.
What do the three types of ecological pyramids illustrate?
Pyramids of energy show the relative amount of energy available at each trophic level of a food chain or food web. (:
What shows the comparative amount of energy available at each feeding level in the environment?
The ecological pyramid, also known as the trophic pyramid, shows the comparative amount of energy available at each feeding level in the environment. It visually represents how energy decreases as you move up the food chain from producers to herbivores to carnivores.
Each step in a food chain or food web?
trophic level
How many xp do you need to get to level 14 on Dragon City?
To reach level 14 in Dragon City, you need a total of 6,000 experience points (XP). Each level requires an increasing amount of XP, and level 14 is one of the milestones that players aim for as they progress in the game.
What type of diagram shows the amount of biomass available in each level in the food chain or food web?
This is called a pyramid. The base is very wide and top is very, very narrow.
What level is the greatest amount of energy available at?
The highest amount of energy available is at the trophic level of producers, such as plants, because they can harness energy from the sun through photosynthesis. This energy is then passed on to herbivores, carnivores, and so on, but some energy is always lost at each step in the food chain.
