Question

what is the mass of an earthworm? select the better estimate. 5 grams 5 kilograms

Explanation:

To determine the better estimate for the mass of an earthworm, we compare the two units: grams and kilograms. A kilogram is much larger (1 kilogram = 1000 grams). Earthworms are small organisms, so 5 kilograms (which is very heavy, like a small animal or a large object) is unrealistic. 5 grams is a reasonable mass for an earthworm.

Answer:

5 grams
