Q. How does biomagnification affect a food chain?
In many cases, animals near the top of the food chain are most affected because of a process called biomagnification. This is biomagnification, and it means that higher-level predators-fish, birds, and marine mammals-build up greater and more dangerous amounts of toxic materials than animals lower on the food chain.
Q. What is biomagnification in a food chain?
The term food web biomagnification is used to describe trophic enrichment of contaminants within food webs and refers to the progressive increase in chemical concentrations with increasing animal trophic status.
Q. How does biomagnification affect trophic level?
Biomagnification (also called food web magnification or food web accumulation) is the progressive increase in the concentration of contaminants in organisms as the trophic level increases. This means lower trophic levels generally have smaller concentrations of contaminants than higher levels.
Q. What is bio magnification which organism in this food chain will be most affected by this phenomenon Why?
Biological magnification refers to the process of increase in the concentration of a toxic chemical with increasing trophic level in a food chain. Harmful or poisonous substance such as DDT sprinkled to kill pests on plants enter the food chain. The tertiary consumers get more higher levels of these chemicals.
Q. What animal is in the highest trophic level?
Apex predators are at the top of the food chain and have no predators of their own. They allow each different trophic level to sustain stable levels of animals. Lions, alligators, bears, anacondas, killer whales and hawks are common apex predators.
Q. Why can a food chain have more than 4 trophic levels?
Answer. Any food chain has a maximum of only 4 or 5 trophic levels. This is because according to the 10% law of transfer of energy, only 10% of the energy of any organism at a perticular trophic level is available to another organism at the higher trophic level…
Q. Why the number of steps in food chain is limited?
The other organisms in the food chain are consumers – they all get their energy and biomass by consuming (eating) other organisms. Most food chainsare quite short, and they rarely consist of more than four steps. This is because a lot of energy is lost at each step.
Q. What is the significance of studying a food chain?
A food chain shows how energy is transferred from one living organism to another via food. It is important for us to understand how the food chain works so that we know what are the important living organisms that make up the food chain and how the ecology is balanced.
