Could you please tell me their life cycles ? Does anyone of you work

In summary, the conversation is about the life cycles of worms and whether anyone works with them on a daily basis. There is a mention of a website that studies the effects of chemicals and environment on worm life cycles, as well as a few resources for more information on worms. The conversation also includes a personal anecdote about a neighbor discussing worms having two heads, mouths, and eyes, which the speaker is skeptical of. The speaker also expresses discomfort at seeing worms after rain and finds them easier to understand than other underground organisms.

Could you please tell me their life cycles ? Does anyone of you work with worms daily ? I am sorry, i mean your research, your job ?

Thank you very much

Are talking about Earth worm. Worm is general term for a large group of organism. see http://www.howe.k12.ok.us/~jimaskew/bworm.htm

As far as Earth worm goes, there is a http://www.nrs.mcgill.ca/whalen/index.html that works with worm. They are look at the effect of chemicals and enviromental on the worm life cycle. They are also running an experiment to quantify the change done by worm in soil. They are looking at different species also.

Here some resources

I vividly recall that when I was around nine, an elderly neighbor of mine, stalk of grass between his teeth and shovel in his gloved hands, pointed to the ground he had been spading in his yard. "See those two worms, sonny boy? A minute ago them was one worm. Don't worry, though. Both parts, they'll keep living. It's got eyes and a mouth at both ends, see."

I was a little skeptical of his information, and I guess I still am.

I know worms have 2 heads, mouth, eyes, they run in both directions. I feel a little uncomfortable whenever i see them running out from grass,bush after rain, they lengthen as long as they can on the gound, I can see even what is inside their bodies.
Worms I think are much easier than viruses or any other undergound organisms...
 

FAQ: Could you please tell me their life cycles ? Does anyone of you work

What is the definition of a life cycle?

A life cycle refers to the series of changes and developments that an organism undergoes from birth to death, including growth, reproduction, and aging.

How do scientists study the life cycles of organisms?

Scientists study the life cycles of organisms through various methods such as observation, experimentation, and genetic analysis. They also use models and simulations to better understand the stages and processes involved in a life cycle.

Can you provide an example of a life cycle?

An example of a life cycle is the butterfly, which goes through stages of egg, larva, pupa, and adult. During these stages, the butterfly undergoes physical and behavioral changes until it reaches its final form.

Why is it important to study life cycles?

Studying life cycles allows scientists to understand the processes and patterns of growth, reproduction, and development in different organisms. This knowledge can be used to make predictions and inform conservation efforts.

Do all organisms have life cycles?

Yes, all organisms have life cycles, including plants, animals, fungi, and bacteria. While the specifics may vary, all living things go through a series of stages and changes throughout their lives.
