Homeostasis is the maintenance of a stable level of internal conditions even though environmental conditions are constantly changing. Metabolism is the sum of all the chemical reactions that take in and transform energy and materials from the environment.
Homeostasis is the natural state of equilibrium; the body attempts to maintain this equilibrium by constantly reacting to external forces that attempt to disrupt the fine balance. It involves the maintenance of the internal environment constant, this involves conditions such as blood sugar, body temperature, among other factors that enhance functions in the body. Through homeostasis organisms tend to resist changes in order to maintain a stable, and a constant internal environment.
The purpose of studying and dissecting an earthworm is to help us understand other organisms. Earthworms are organisms that are tube-shaped, segmented worms that belong to the phylum Annelida and in the species Lubricous. Earthworms decompose organic matter, break it into usable nutrients for their local ecosystems and recycle compost.
