The amino acids and proteins bond together forming rings/chains which result in energy storage. The waste products are exited thru the anal sphincter
because they make it so plants can breath by making tunnels
The answer is that earthworms help to build soil and fertilize
because they create tunnels in the soil which makes air pass through
Earthworms might look smooth but they have bristles, called setae, that help to hold them in their tunnels.
Earthworms are an important part of the soil environment, and the growth of plants. Oil is deadly to earthworms.
Earthworms, which are a type of segmented worm, help out plans by digging tunnels in the soil which gives plants oxygen.
From ingestion of food sources if they are dead and through movement from and to their tunnels are ways in which earthworms can be found in the manure of pigs. For example, if the invertebrates in question are not alive, then they most likely were in the pigpen mud whereas if they are not dead, then they probably are moving back and forth between underground tunnels (particularly if their homes are flooded by recent rain events).
Tunnels provided cover and concealment.
the ants dig tunnels that rarely collaspe by spreading silk(from larvea), saliva and feces over tunnels dug with their jaws.
so they can start it from underground

Everything that has to do with civil engineering is based upon the measurements of land surveying. Surveying gives the measurements that are vital to build things such as buildings, bridges, tunnels and other important things.
