false for plato users:)
No, they cannot,because they are herbivores. I read somewhere that it will mess up its digestion if it eats meat...
This question cannot be answered properly because someone may be reading right now. so this question cannot be answered because the answer would change frequently
because they eat things in a form that they cannot use, therefore they must digest it to transfer it to a usable form.
Birds and moles that are immune to this and cannot be internally harmed by the leeches. Also, some fish may be immune to the leeches too, so they would also be able to eat them.
When the wall of the stomach cannot protect the organs from digestion, it is the result of a gastric ulcer.
Leeches are a type of segmented worm that belong to the class of animals known as oligochaetes, earth worms are also in this class of animals. What make Leeches different from many other animals is their food and how they obtain it. Leeches live off the blood of other animals making them a type of parasite. A parasite is an animal who has developed the need to feed off of other animals. Leeches secrete an enzyme that actually numbs the area where it chooses to feed as well as breaking down skin tissue so they can easily suck up the blood of their host animal. It would stand to reason that not only would leeches prefer baby animals because there skin is more supple and not quite as thick but also maybe because the baby animal may have some of the vitamins and minerals present that the leech cannot get from an adult animal because the animal is nursing. Leeches are sometimes used by doctors even today to suck out blood in a diseased portion of the body. Yuck!
If you mean "absorption" when you say "circulation", digestion is necessary because the body cannot absorb the nutrients directly from food. The nutrients are "locked" inside. Digestion breaks food apart so that nutrients can be more easily accessed and absorbed.
Leeches are invertebrates. They live in shallow ponds and lakes, among plants. They hook on to creatures like us, and cut a minor hole in our body, and suck our blood. It cannot drain much blood unless you don't notice it for a long time. They used leeches back in the 1600's, as a remedy to "bad blood."
No. Frequently is an adverb. And it cannot be a preposition.
No, minerals cannot be broken down by digestion. They remain intact and are absorbed by the body in their original form.
Enzymes are involved in the digestion of all types of foods except, of course, the foods that cannot be digested (like cellulose).
cellulose and insoluble fibers
