In a heterogeneous mixture, the components are mixed unevenly and you can see the different thing in the mixture, while in homogeneous mixture (aka solution), the parts are evenly mixed together.
The correct answer is that the components are mixed unevenly instead of evenly within the heterogeneous mixture.
A heterogeneous mixture basically refers to any kind of mixture, which is not uniform in composition. It is an uneven mixture of smaller component parts. In the heterogeneous mixture, with the help of certain procedures, the mixture can be separated from each other.
On the other hand, a homogeneous mixture refers to a liquid, solid, or gaseous mixture, which exhibits the similar ratios of its constituents all through a given sample.
The terrestrial food web is a food web that is characterized by all land animals and is largest terrestrial food chain on earth as the farmer tends to introduce a rat poison in this food web the rat may get killed by the medicine but if the same rate may be eaten by a snake the poison that killed the rat may infect the snake.
Hence the pollutant may climb up the ladder and intoxicate the hawk that depends on small animal for prey which may be further eaten by a man or other animal like a cat may then spread this disease or the infection to other upwards in the food chain and thus the process of Biomagnification takes place in the ecosystem.
