The endocrine system consists of the endocrine glands that release hormones directly int the blood. Those hormones bind to their receptors on the target cells and thus regulate their function. The major glands are:
pineal gland-releases melatonin, controls sleep cycle
pituitary gland-control growth, blood pressure, thyroid glands and metabolism etc.
pancreas-secretes insulin and glucagon, control of blood sugar levels
ovaries, testes-reproductive role (release female and male hormones)
thyroid gland-controls metabolism and protein synthesis
parathyroid gland-controls Ca levels
hypothalamus-connects nervous and endocrine systems, controls other glands
adrenal glands-release adrenalin and steroid hormones.
Food web is more appropriate because of how wide spread the animal kingdom is, there are many predators for many different animals. For example, if a rabbit is killed by a wolf and the wolf eats a part of the carcass and leaves it, soon other scavengers will come and eat the remains, which then spans out into a web of animals, which allows us more data than what a chain may give us to visualize.
