Answer:
Biological magnification refers to a phenomenon where some of the substances like heavy metals or pesticides move up the food chain, make their way into the lakes or rivers, and are eventually consumed by aquatic species like fish. This, in turn, is further consumed by large species like large birds, humans or animals.
This is associated with the health warnings given to pregnant women as too much eating of some kind of fish may influence the immune systems, that is, may affect the health of women who are pregnant.
Soil creep is the downward movement of soil, on a slope, caused by the force of gravity. A slow deformation of soil material over a prolonged period of time, from pressure and stress. Creep occurs when the friction from materials resisting gravity move against each other. Slope is a key cause of soil creep.
Answer:what is the answer
Explanation:
<span>This is because benthic zone are too
dark to support photosynthesis. Due to their depths, sunlight is unable to penetrate
the above lying waters and reach the region. This way plants cannot carry out
photosynthesis hence cannot grow. This is why only </span>decomposers,
detritus feeders can be found in the benthic zone.
