Hierarchy of Life

Arrange the following terms from smallest to largest. Biome Organelle Biosphere Population Atom Community Proton, electron,,neutron Organ system Gluon, quark, lepton Organ Cell Organism Molecule,compound Element

Gluons “glue” Quarks (6 flavors) Up (+2/3 charge) Down(-1/3 charge) Top Bottom Strange Charm Leptons (6 flavors) Electron Electron neutrino Muon Muon neutrino Tau Tau neutrino

Sub-atomic particles Protons (uud) +1 charge, in nuc., 1 amu Electrons -1 charge, outside nucleus in shells, 0 a.m.u Neutrons (udd) “neutral”, in nucleus, 1 a.m.u.

Atoms Smallest unit of an element that maintains all the properties of that element. A combination of protons, neutrons and electrons

Elements Protons determine the element S, P, O, N, C, H, Draw a pie graph of elements in the Earth, and in living things. Note the 2 main elements of the atmosphere

Molecules and Compounds When atoms bond together Water, glucose, proteins

Organelles The parts of a cell Nucleus Mitochondria Endoplasmic reticulum Vacuole Ribosome

Cells Smallest unit of life Brain Nerve Muscle Fat Blood

Tissues Composed of cells with a similar structure and function Blood Bone Adipose

Organs Tissues performing a particular function Heart Lung Brain Liver

Organ system Nervous Skeletal Lymphatic Respiratory Muscular Endocrine

Organism You are an organism Cat Bird Mouse

Population Organisms in an area of the same species that reproduce Oak trees Walleye Perch Dogs

Community A collection of populations in an area Pond community Forest community

Biome Large geographic region with a climax “stable” community Tundra Tiaga Desert Tropical rain forest

Biosphere The living planet
