Biology Chapter 6

Question 1

Explain how differences in muscle fibers relate to athletic performance.

Answer 1

Different people’s muscles are naturally composed of different ratios of fast- and slow-twitch fibers, which are good for different types of activities

Question 2

Explain why photosynthesis is important to most ecosystems.

Answer 2

Because photosynthesis converts inorganic nutrients to organic matter that the rest of the ecosystem can digest.

Question 3

Define and compare autotrophs and heterotrophs, producers and consumers.

Answer 3

Autotrophs (producers) create their own food from inorganic nutrients, ecosystem depends on their energy input.

Heterotrophs (consumers) draw their food from the environment

Question 4

Explain how the processes of photosynthesis and cellular respiration are complementary to each other.

Answer 4

The fuel for photosynthesis (CO₂ and H₂O) are the waste products of cellular respiration. The fuel for cellular respiration (Oxygen gas) is a waste product of photosynthesis.
