multiple answer 1 point
watch the video linked at the top of page 10.
which best summarizes the relationship between a healthy sequoia forest and fires? choose 2.
suppressing all fires is the healthiest system, as all fires harm the sequoias.
giant sequoias need fires to germinate. more frequent, low intensity fires are part of the natural life cycle
there are no laws governing the threat of forest fires, so it is up to each individual to decide what is best.
by suppressing small fires, and allowing the build up of biomass, larger fires are taking place.

Explanation:

To determine the correct answers, we analyze each option:

• Option 1: Suppressing all fires is not healthy for sequoia forests as some fires are beneficial (e.g., for germination), so this is incorrect.
• Option 2: Giant sequoias need fires to germinate, and more frequent, low - intensity fires are part of their natural life cycle. This aligns with the ecological relationship between sequoia forests and fires.
• Option 3: There are laws and management practices regarding forest fires, so this is incorrect.
• Option 4: Suppressing small fires leads to biomass build - up and larger, more destructive fires, which is a known ecological consequence. This also correctly describes the relationship.

Answer:

1. Giant sequoias need fires to germinate. More frequent, low intensity fires are part of the natural life cycle
2. By suppressing small fires, and allowing the build up of biomass, larger fires are taking place
