The liver produces bile which emulsifies (separates) fat.
Reproductive (haploid) cells known as gametes have half as many (23) pairs of chromosomes as normal (diploid) cells. When the male gamete (sperm) combines with the female gamete (ovum) through meiosis to form a zygote, each gamete supplies half the chromosomes needed to form the normal diploid cells.
The respiratory system manages respiration which is the process by which blood cells absorb oxygen and eliminate carbon dioxide.
Like decomposers, scavengers also break down the dead bodies of plants and animals into simple nutrients. The difference is that scavengers operate on much larger refuse and dead animals (carrion). Decomposers then consume the much smaller particles left over by the scavengers.
The narrowest classification of life, species, contains organisms that are so similar that they can only reproduce with others of the same species.
