No skeleton, it may look like it but there isn't one. Because when you squish the worm there is nothing but flesh and blood.  However there is a certain type of worm that has a skeleton just not an earthworm. (I don't know what the name is of the worm that has a skeleton.)
Hope this helps:)

A work has no skeleton, which is why it can bend in all different directions, but the main reason i know this, is cause if you pinch a work between your thumb and forefinger, it will break, and there is nothing on the inside of the worm that indicates there is a skeleton

Which organism in the food web below is likely to store the least energy?
tankabanditka [31]

Answer;

-Cougar

Explanation;

-The amount of biomass decreases from the lowest trophic level to the highest.  In all the ecological pyramids, producers (organisms that produce their own food) are found at the lowest trophic level. This trophic level contains the highest amount of energy.

-The organisms in the highest trophic level receives the lowest amount of energy. This is because only 10% of energy moves from one level of the food pyramid to the next. When heat comes from the sun. 90% of it is lost to the environment, 10% is consumed by the plants (primary producer). As a primary consumer ingests the plant, 90% of the original heat from the sun is lost to the environment and the primary consumer receives 10%. The secondary consumer receives 10% and 90% is lost, and so forth.
