What is magnification in biology microscope?
Magnification is how many times bigger the image of a specimen observed is in compared to the actual (real-life) size of the specimen.
What is magnification short answer?
In optics, It is a quantification of comparing the size of the image with respect to the size of the object. It gives us information about the image in terms of how large or small is the image formed. Magnification is defined as the ratio of the height of image to the height of object. m=hiho.
What is magnification in biology class 10?
The process by which the harmful and toxic substances enter the food chain and get concentrated in the body of living organisms at each successive level in food chain is called biological magnification.
What is magnification explain with example?
The accumulation of chemicals in the top most organism of the trophic level or food chain is called biological magnification. Example: Farmer sprays pesticides on the crops which enters the food chain from crops these pesticides enter into the organisms that feed on it.

What is magnification in Brainly?
Magnification is the ratio between the image height and object height. Explanation. Magnification is nothing but a process of enlarging the apparent size of the object. Magnification is defined as the ratio between the apparent size of the object to the actual size of the image.
What is magnification Vedantu?
Magnification can be defined with the height of the image as well as the distance of the object. It is the ratio between height of object and height of image. It is denoted by “m” in the mathematical formula.
What is biological magnification Class 12?
Biomagnification is the accumulation of toxic substances in living organisms at higher levels compared to non-living environments.. These toxic substances are usually heavy metals like mercury and arsenic and pesticides like DDT. The biomagnification process affects the entire food chain.
What is biomagnification Ncert?
Biomagnification refers to increase in concentration of the toxicant at successive trophic levels. This happens because a toxic substance accumulated by an organism cannot be metabolised or excreted, and is thus passed on to the next higher trophic level.
What is the magnification of the diagram?
Drawing magnification = drawing size / actual size.
What is magnification in biology drawing?
The term magnification may be used in two ways: This is used when referring to an illustration (drawing or photograph) of an object. In this way, the term magnification tells you how the size of the illustration compares with the actual size of the object.

What is the magnification class 10th answer?
Magnification is defined as the enlargement of the image formed by a mirror, whether it is a concave mirror or a convex mirror, relative to the size of the object.
What is magnification of lens Class 10?
The ratio of height of image and that of object or ratio of distance of image and distance of object gives magnification. It is generally denoted by 'm'.
What is magnification in mirror Class 10?
Magnification is the increase in the image size produced by spherical mirrors with respect to the object size. It is the ratio of the height of the image to the height of the object and is denoted as m. The magnification m is given by m=−vu.
What is magnification of lens class 10th?
Magnification of a lens is defined as the ratio of the height of an image to the height of an object. It is also given in terms of image distance and object distance. It is equal to the ratio of image distance to that of object distance.
What is biological magnification Byjus?
Biomagnification, also known as bioamplification or biological magnification, is the increasing concentration of a substance, such as a toxic chemical, in the tissues of organisms at successively higher levels in a food chain.
What is biomagnification and bioaccumulation?
Bioaccumulation takes place in a single organism over the span of its life, resulting in a higher concentration in older individuals. Biomagnification takes place as chemicals transfer from lower trophic levels to higher trophic levels within a food web, resulting in a higher concentration in apex predators.
What is biological magnification class 12th?
Biomagnification or biological magnification is a gradual increase in the concentration of toxicants at successive trophic levels. Certain toxic substances present in industrial waste undergo biomagnification.
What is an example of biological magnification?
Biomagnification is defined as the accumulation of a particular substance in the body of the organisms at different trophic levels of a food chain. One example of biomagnification is the accumulation of insecticide DDT which gets accumulated in zooplanktons. Small fishes consume these zooplanktons.

What is magnification measured in?
Linear or Transverse magnification For real images, such as images projected on a screen, size means a linear dimension (measured, for example, in millimeters or inches).
What is the formula for magnification on a microscope?
Calculation of Magnification: To calculate the linear magnification of a drawing or image, the following equation should be used: Magnification = Image size (with ruler) ÷ Actual size (according to scale bar)
What is magnification write its unit?
Magnification has no SI unit because magnification is a ratio of numbers and ratios dont have units. See that Magnification=h'/h , where h' is image height and h is object height.
What is magnification in physics Brainly?
Expert-verified answer Magnification is defined as the ratio between the apparent size of the object to the actual size of the image. As, magnification is a ratio of the two similar quantities, so it will be dimensionless in nature.
What is the SI unit of magnification?
Magnification is a ratio of lengths, hence it has no units.
What is biological magnification Class 8?
“Biomagnification or biological magnification is the process of accumulation of certain chemicals in living organisms to a concentration higher than that occurring in the inorganic, non-living environment.”
What is biomagnification Class 9?
Biomagnification is the increase in the concentration of non-biodegradable substances in a food chain.
What is the difference between biomagnification and biomagnification?
The process of a buildup of certain chemical substances or toxins at the higher trophic levels of a food chain is termed as Biomagnification….Biomagnification and Bioaccumulation – Differences.
| Biomagnification | Bioaccumulation |
|---|---|
| An increase in the level as one moves higher in the food chain. | An increase in the concentration of a substance inside an organism |
