In your assigned readings, you learned how size limits the distribution of gases, water and nutrients in animals. Chose a simple/small animal and a complex/large animal and compare the use of organ systems to meet a metabolic or reproductive need. You will focus on a single function; e.g., respiration, circulation, digestion, excretion, or reproduction. In your opinion, does increased size provide an adaptation for this function? Explain your position.
Write a 2-3 page (500 – 750 words, 12 point font) paper including the following elements. Be sure to compose your work with your own words. Do not copy and paste from any source.
Analyze the limitations size puts on function.
Describe an organ system needed for a small animal.
Describe an organ system needed for a larger animal.
Compare and contrast the system in small and larger animal.
Analyze increased size as an adaptation and explain the rationale.
