Notes

2. The study of zoology focuses on all kinds of animals. Whether big or small, zoology looks into their biology; the how and why behind their environments; as well as ways to sustain their lives alongside humankind. Through the study of zoology, you can gain an understanding of the natural world and how we can help with conservation. (Why Is Zoology Important?, n.d.)

3. General characteristic of Living Organism: Movement, Respiration
Movement – An action by an organism or part of an organism causing a change of position or place
Respiration – The chemical reactions in cells that break down nutrient molecules and release energy for metabolism
Sensitivity – The ability to detect or sense stimuli in the internal or external environment and to make appropriate responses
Growth – Permanent increase in size and dry mass by an increase in cell number or cell size or both
Reproduction – The processes that make more of the same kind of organism
Excretion – Removal from organisms of the waste products of metabolism (chemical reactions in cells including respiration), toxic materials, and substances in excess of requirements
Nutrition -Taking in of materials for energy, growth and development; plants require light, carbon dioxide, water
