Parasites are organisms that live on or inside another organism (the host) and benefit at the expense of the host. They can cause harm to the host by feeding on its tissues, cells, or bodily fluids.
Types of Parasites
There are three main types of parasites:
Ectoparasites: These are parasites that live on the surface of the host's body, such as fleas, lice, and ticks.
Endoparasites: These are parasites that live inside the host's body, such as intestinal worms, protozoa, and tapeworms.
Parasitoids: These are organisms that lay their eggs inside the host, and the larvae develop by feeding on the host's tissues, eventually killing it.
Life Cycle of Parasites
Parasites have complex life cycles that often involve multiple hosts. The life cycle may include stages such as egg, larvae, pupa, and adult, and may involve both sexual and asexual reproduction.
Energy - A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc 2 . B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion. C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy. D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields. E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.
