The taxonomic kingdom Protista is a collection of single-celled organisms that do not fit into any other category. Protists are a group made up of protozoa, unicellular algae, and slime molds. We will concentrate on the animal portion of this group: the protozoa (proto = first, zoa = animals). Protozoa are the oldest known group of heterotrophic life that consume and transform complex food particles into energy. Although protozoans are only made up of a single cell, these organisms manage to perform all the basic tasks of life. The protozoa are divided into four major groups: the ciliates, the flagellates, the heliozoans, and the amoebas.

Some pension plans require the employee to make a small, periodic contribution to the fund. The amount of pension that a pensioner receives depends on the type of pension plan. Pension plans generally can be divided into two categories: defined benefit plans and defined contribution plans. A defined benefit plan provides a set amount of benefits to a pensioner. Under a defined contribution plan, the employer places a certain amount of money in the employee's name into the pension fund and makes no promises concerning the level of pension benefits that the employee will receive upon retirement.
