Transcript of 7 Characteristics of Life: Worms

Any behavior of a living organism that results from an external or internal stimulus.
To discharge (waste matter, urine, sweat, carbon dioxide, or faeces) from the body through kidneys, lungs, bowels, etc ( of plants) to eliminate waste matter, such as carbon dioxide and salts) through the leaves and the roots.
The chemical process that occurs within a living organism in order to maintain life.
Keeping the body in a steady or normal state; pH level, carbon dioxide level, sugar level, and temperature.
To make an copy, duplicate, or close imitation.
The process of increasing in physical size.
7 Characteristics of Life: Worms
The act or process of nourishing or of being nourished. The process by which organisms take in and utilize food material.
-Earthworms can regenerate: which means if a part of their body is removed they can grow it back over time.
-Earthworms breath through their skin, this is why they must stay moist.
-Earthworms do not have eyes, they are light sensitive. Exposing one to light can paralyze it, if paralyze for up to an hour it will most likely die.
-If a worm's skin has been dry for too long, it will die.
"The annual respiratory metabolism of the Brogden's Belt earthworms was calculated to be between 10.7 and 13.41, which is equivalent to between 4.1 and 5.1% of the total soil metabolism. A production/biomass ratio of 0.49-0.58 was estimated, as a net population efficiency of 22%." (S.R.J. Woodell, link.springer.com/article/10.1007%2FB00348115)
Worm's pH levels changes due to their location.
"Earthworms prefer pH levels of 6.5 to 7.5." But if in captivity " Rock phosphate, seaweed, and fish extract organic fertilisers give good results, but more importantly is the continual use of organic matter such as chicken manure or compost." (wormsurus.co.nz/aboutearthworms.html)
"An earthworm can only grow so long. A well-fed adult will depend on what kind of worm it is, how many segments it has, how old it is and how well fed it is. For example an Lumbrius Terrestris will be from 90-300 millimeters long." (urbanext.illinois.edu)

Fun Fact: The world's longest Earthworm was found in Africa and it was emasured to be 22 feet long.
Earthworms are hermaphroditic, meaning all of them can reproduce, male or female.
Worms are hatched from eggs, but there is a strange way the eggs come about.

Fun Fact: Worms actually can never be pregnant because of the way they reproduce.
Worms have very small mouths, they only eat things like bacteria, fungi, and protozoa. They also eat dying plants and living. They eat decaying animals. Sometimes the pieces of food are too big for their mouths so they moisten them to make them soft and they just suck it in its little mouth.
Fun fact: Worms have their own tiny built in food processor: it is called a Gizzard. Worms do not have a digestion system like humans. When food enters the gizzard, all the food particles rub against each other and are being moisten by the worm, and it turns into a mini smoothie then it moves throughout the body.
Worms breath through heir skin, so they have to stay moist. They produce a musuc type liquid to keep their skin moist.
Worms do have butts like every other living creatures.

Fun Fact: "Earthworms do not have a skeleton. Liquid called coelomic fluid, fills inner part of the worm's body and provides shape and structure." (softschools.com/facts/aniamals/earthworms_facts/629/)
