Question

below is a food web from a tundra ecosystem in nunavut, a territory in northern canada.
in this food web, which organisms contain matter that eventually moves to the earthworm?
select all that apply.
short - tailed weasel brown lemming parasitic jaeger
bilberry snowy owl

Explanation:

Earthworms are decomposers, so they break down dead organic matter from organisms at all trophic levels.

1. Bilberry: As a producer, when it dies, its matter is decomposed by earthworms.
2. Brown lemming: When this consumer dies, earthworms break down its remains.
3. Short-tailed weasel: As a predator, its dead body is a food source for decomposers like earthworms.
4. Snowy owl: This top predator's remains are decomposed by earthworms after death.
5. Parasitic jaeger: When this bird dies, earthworms will decompose its organic matter.

All these organisms' matter can eventually move to earthworms through decomposition.

Answer:

• short-tailed weasel
• brown lemming
• parasitic jaeger
• bilberry
• snowy owl
