Answer to question #1:

Directly affects the organs and tissues of plants.

Pollute the soil, reduce fertility.

Reduce plant productivity.

Answer to question #2:

The tail in animals performs various functions, among them:
1) mechanical (is a support when running, jumping for kangaroos, is a steering wheel for flying, swimming for birds and fish):

a) tail as a balancer (in squirrels, martens, lemurs);
b) the tail as a steering wheel and a brake (crocodiles, dolphins, fish);
c) climber's equipment (the tail helps many animals to climb tree trunks and sheer cliffs)
2) physiological (self-defense in lizards; rat lemurs accumulate fat on rainy days):

a) the tail as a means of defense and attack (at the base of the tail, a long, flat, serrated and sharp spike grows at the base of the stingray, with which it defends itself when attacked).
3) sociable (Animals communicate with each other by waving their tails. Moreover, visible signals are accompanied by odors. The fact is that some animals have odorous glands on the tail. It is known that with the help of such glands deer can warn each other about trouble, spreading the so-called "smell of danger" ):
4) Amazing tail features :
a) using it for storage (jerboas, deposit excess fat at the base of the tail;
b) arctic foxes, foxes, martens, sables and snow leopards - use their fluffy tail as a warm woolen blanket;
c) in some animals, the tail replaces the gills. Tritons have lungs. Therefore, they have to constantly float to the surface of the water for new portions of air. During mating games and they have no time to spawn. Males rescued by the tail. Under his thin skin, a mass of blood vessels and oxygen easily penetrates into the blood.

Answer to question #3:

1. A large number of released minks will undermine the food base and disrupt the established food ties.

2. Most of the released minks will die, as animals raised in captivity are not adapted to find food for themselves, hide from enemies, and are not adapted to severe frosts.

3. The American mink is bred. We can assume that in the wild it will displace the local European mink, which is less competitive, or this event will not affect the local fauna, since these animals can be easy prey for predators.
