These specimens are a roly-poly and a fly. I found these specimen in front of my house.
They relate to eukaryotes because they are insects and insect cells are eukaryotic. Eukaryotes are any of the single-celled or muticellular organisms whose cell contains a distinct, membrane-bound nucleus.

Detritovore: snails

This specimen is a snail. I found this specimen outside of my house stuck to the wall. Snail is related to a detritovore because snails consume dead organic matter. A detritovore is an organism that feeds on detritus.

Hermaphrodite: snails

A bee is related to pollinator because bees travel from flower to flower, collecting nectar and pollen grains. Pollinator is the biotic agent that moves pollen from the male anthers of a flower to the female stigma of a flower to accomplish fertilization.

Protein: egg whites

This specimen is egg white. I found this specimen in my refrigerator. 
The egg white is related to protein because egg whites contain 10% protein. Protein is any group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen and are composed of one or more chains of amino acids.

Sporophyte: pine trees

This specimen is a pine tree. I found this specimen in front of my house. A pine tree is related
to a sporophyte because it has roots, stems and leaves. Sporophyte is the spore-producing phase in the life cycle of a plant that exhibits alternation of generations.

Xylem: tree rings

This specimen is a tree ring. I found this specimen in front of my house. A tree ring relates to a xylem  because xylem tissues transport water and nutrients from the roots of the tree and after the vascular cylinder is formed, a tree's first ring will appear. A xylem is one of the two types of transport tissue in vascular plants.
