Read Slide 5. Which statement best explains the importance of both mechanical and chemical digestion in humans and frogs?(1 point) Responses Mechanical digestion only occurs in humans, while chemical digestion only occurs in frogs. Mechanical digestion only occurs in humans, while chemical digestion only occurs in frogs. Mechanical digestion breaks down food physically, while chemical digestion uses enzymes to break down food into nutrients in both organisms. Mechanical digestion breaks down food physically, while chemical digestion uses enzymes to break down food into nutrients in both organisms. Both mechanical and chemical digestion are not necessary in humans and frogs as they have different digestive needs. Both mechanical and chemical digestion are not necessary in humans and frogs as they have different digestive needs. Mechanical digestion uses enzymes to break down food into smaller pieces, and chemical digestion breaks down food physically.

Answer 1

The statement that best explains the importance of both mechanical and chemical digestion in humans and frogs is:

"Mechanical digestion breaks down food physically, while chemical digestion uses enzymes to break down food into nutrients in both organisms."

This statement accurately describes the roles of mechanical and chemical digestion in both humans and frogs. Mechanical digestion involves the physical breakdown of food into smaller pieces, which increases the surface area for enzymes to act upon during chemical digestion, where food is further broken down into nutrients.
