The food chain, just from common knowledge, would be
fruit trees, birds, monkeys, tigers.
The fruit trees cannot prey on anything. The birds eat the fruit, the monkeys can catch birds and eat them, and the tigers can eat the monkeys.
The organ you're looking for is the liver.

Special proteins are in charge of regulating the movement of substance through the double-membrane.
Answer:
Sperm undergo more mitotic cellular divisions than egg and therefore have a higher risk of developing a spontaneous mutation.
Explanation:
As you have seen in the question above, lycanthropy is a mutation that is more likely to be established as the supply of male gametes comes from older men. This is because sperm undergo more mitotic cell divisions than eggs, and therefore are at greater risk of developing a spontaneous mutation.
In order for you to understand this, you need to know that eggs (which are female gametes) are produced at once in a woman's body. Thus, cell division is limited and therefore the opportunity for spontaneous mutations to occur is also limited. However, men produce sperm from adolescence to death, creating the need for countless cell divisions, which can develop genetic errors that create spontaneous mutations in gametes.
Shleiden and Theodor Schwann were the first to recognize that all plants and animals are composed of cells.
