Question

if an earthworm eats enough matter that it consumes 100 grams of nitrogen in its lifespan, how much nitrogen did it release into the soil

Answer 1

Option C

Step-by-step explanation:

If an earthworm eats enough matter that it consumes 100 grams of nitrogen in its lifespan, how much nitrogen did it release into

the soil?

(A) 10 grams

(B) 27 grams

(C) 73 grams

(D) 100 grams

Solution -

Worms are considered as eating machines which take in organic matter and break it down into smaller pieces such as nutrients. These nutrients are then taken up by plants.

As per an estimate, an earthworm absorbs nearly 27% of the available nitrogen in their food.

The remaining available 73 percent of nitrogen is broken down and available as nutrients in the soil.

Therefore, out of 100 grams nearly 73 grams of nitrogen is released into

the soil
