A population of white moths lives in a forest near a factory. this factory burns coal and pollutes the air with black dust. over
time, this dust has settled on the trees in the area, making them darker in color. this could result in 1. an increase in the white moth population.
2. a decrease in the white moth population
3. an increase in the number of trees in the area
4. a decrease in the air pollution affecting the area
This is because if the trees are black, and covered with soot due to the pollution, caused by industrialisation, the white moths will be easily seen and constantly hunted by the predator, compared with the black moth population as they camouflage easily. Ultimately, the white moths would be hunted to such an extent that their population would dramatically decrease
Nutrition- microorganisms are able to feed on food materials obtained from the living or dead bodies of plants or other animals. They are therefore heterotrophs.
Movement- both localized and generalized movements which results in the animal moving from one point to another. e.g., using flagella, cilia
Excretion- they lack highly specialized excretory organs but some microorganisms use contractile vacuoles for excretion which removes waste.
