1. In medicine, a reference to a condition caused by dystrophy: Dystrophication is the progressive change that may result from defective nutrition of a tissue or organ.

Dystrophication relates to or is caused by faulty nutrition.
2. In ecology, with reference to a lake or pond, having too low an accumulation of dissolved nutrients to support abundant plant life: Dystrophication is another description of a lake or pond that contains highly acid, brownish waters filled with undecayed plant materials, and eventually developing into a peat bog or marsh.

Dystrophication refers to a lake with high humus material, sparse bottom fauna, and low dissolved oxygen.

1. Progressive degeneration of a body tissue: The condition of dystrophy can relate to a muscle, caused by inadequate nourishment of the affected part, as a result of some unknown cause.

In medicine, dystrophy can be caused by a degenerative, faulty, or inadequate nutrition or development.

In pathology, dystrophy is one of any of a number of disorders characterized by weakening, degeneration, especially muscular dystrophy, in which the muscles weaken and atrophy.
2. A condition in which pond or lake water is unable to support much plant or animal life: A state of dystrophy can arrise in a body of water because of an excessive amount of humus content.

A description of an organism that gets its nutrients from the outside surface of its host: Ectotrophic fungi grow on the surface covering of roots.

The nutritive material that is supplied to the embryo of a placental mammal during development: The embryotroph is the nutrient material, composed chiefly of secretions from the uterine glands, degenerating uterine tissue, and substances in the maternal blood, that nourishes a mammalian embryo prior to the formation of the placenta.

A reference to an organism that grows within roots: An endotrophic fungus receives nourishment from plant roots in a mycorrhizal association.

1. In medicine, the condition of being in eutrophy: In the article, Jane read that eutrophia designated a normal condition of nutrition and health, with a regular development of the total organism.
2. In ecology, with reference to lakes or ponds, characterized by an abundant accumulation of nutrients that support a dense growth of algae and other organisms, the decay of which depletes the shallow waters of oxygen in summer: Eutrophic waters (lakes or ponds) are rich in mineral and organic nutrients which promote a proliferation of plant life, especially algae that reduces the dissolved oxygen content and often causes the extinction of other organisms.

1. In medicine, relating to, characterized by, or promoting good nutrition: Dr. Smart wrote down eutrophic information for his patients so that they would know what good foods to eat.
2, In ecology, referring to a lake or other body of water, containing a rich supply of plant nutrients: Eutrophic lakes are characterized by seasonal periods of oxygen deficiency because of the excessive growth of algae.

To increase the amount of elements, especially nitrogen and phosphorous, in a marine or aquatic ecosystem and the pollution from such sources as sewage effluent or leachate from fertilized fields causes a lake, or pond to become over-rich in organic and mineral nutrients, so that algae and cyanobacteria grow rapidly and deplete the oxygen supply: When water regions eutrophicate, they change in many ways: oxygen disappears from the deep places in water regions first.

When nutrients from the bottom are set free into the water, the process of elements eutrophicate and speed up and because the content of nutrients is rising, the alqae begins to bloom.

When these organic processes eutrophicate in water regions in their natural state, then biological multiplicity decreases, water regions become polluted, and the quality of the environment deteriorates.

The process by which a body of water becomes rich in dissolved nutrients from fertilizers or sewage, thereby encouraging the growth and decomposition of oxygen-depleting plant life and resulting in harm to other organisms: Aquaculture has been resulting in small, but expanding into locally significant emissions of nutrients (nitrogen and phosphorus) into the Baltic Sea, contributing to eutrophication.

The condition of waters (lakes and or ponds) having rich in mineral and organic nutrients that promote a proliferation of plant life, especially algae, which reduces the dissolved oxygen content and often causes the extinction of other organisms: Agricultural fertilizers and many commercial detergents are rich in phosphorus and the pollution of a lake with the addition of more phosphorus to its waters first produces a green scum of algal growth on the surface of the lake and then, if the pollution continues, it proceeds to "kill" the lake.

After the initial bloom of rapid algal growth, aging algae die, and then the bacteria feeding on the dead algae cells use up so much of the lake's dissolved oxygen that fish and invertebrate animals suffocate.

1. In medicine, healthy or adequate nutrition or development; being well nourished: Following Sam's physical check-up, Dr. Smart told him that he was in a condition of eutrophy and could take part in any kind of sports he wanted to!
2. A state of lakes and ponds being over-rich in organic and mineral nutrients: Eutrophy promotes plant life at the expense of animal life.

Eutrophy is a process of becoming eutrophic, especially because of pollution.

A reference to an organism that grows on the outside of external parts of a source: Exendotrophic fungi obtain their nourishment from roots of plants.

A reference to a principle in the extracts of the anterior lobe of the pituitary gland that antagonises the action of insulin and causes hyperglycemia: Glycotrophic substances or hormones influence or regulate the metabolism of carbohydrates in a person's body.

Atrophy of one side of the body or of one half of an organ or part: Hemiatrophy has been reported in association with a variety of neurologic conditions, including parkinsonism. Patients with the hemiparkinson-hemiatrophy syndrome (HP-HA) have asymmetric parkinsonism with limb atrophy on the more affected side.

Underdevelopment of one lateral half of the body: Leah read about hemidystrophy as being the very sad condition regarding the unequal growth of the two lateral halves of a person's body.

Muscular or osseous hypertrophy of one side of the face or body: Mary's old Aunt Gladys had a case of hemihypertrophy which affected only one side of her body, and therefore she had lots of help in her home.
