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.
