Answer 1

1. Based on the complexity of the GI system, herbivores can be classified into 3 types. They are

• Concentrate selectors: Can digest limited or no fiber
• Intermediate feeders: Can digest intermediate fiber
• Roughage feeders: Can digest high volume fiber.

2. The 3 mechanisms which urinary system uses are as follows
