question 52 (1 point)
which factor is most directly improved by decomposers in an ecosystem?
a carrying capacity of predators
b geographic range of producers
c oxygen levels in the air
d soil fertility

Explanation:

Question 1 (Why are decomposers important for ecosystems?):

• Option a: Decomposers break down dead organisms and waste, releasing nutrients like nitrogen, phosphorus, etc., back into the soil for producers to use. This is a key role of decomposers in nutrient cycling.
• Option b: Decomposers don't provide shelter for animals; structures like plants or rocks do that.
• Option c: Decomposers don't prevent plant growth speed; factors like resource availability or competition do.
• Option d: Decomposers get energy from dead matter, not competing with producers (who make energy via photosynthesis) for energy.

• Option a: Predator carrying capacity depends on prey availability, not directly on decomposers.
• Option b: Geographic range of producers is about where they can grow, not directly improved by decomposers.
• Option c: Oxygen levels are mainly from photosynthesis (producers), not decomposers (decomposers respire, using oxygen).
• Option d: Decomposers release nutrients (like nitrogen, phosphorus) into the soil, which directly increases soil fertility, helping producers grow.

Answer:

a. They recycle nutrients back into the soil
