species of earthworm that are found all over the world. They live in soil and play an important role in our ecosystem by assisting with the decomposition of organic matter. They also aid in nutrient cycling and are integral in creating a healthy soil environment for plants and animals. ...
organ, in biology, a group of tissues in a living organism that have been adapted to perform a specific function. In higher animals, organs are grouped into organ systems; e.g., the esophagus, stomach, and liver are organs of the digestive system. In the more advanced animals, there are...
In smaller species, these systems progressively emerge, and in higher animals, they reach their full complexity and functional specialization. The reproductive organs (such as flowers, seeds, and spores) and the stem, root, and leaf are the major organs of plants. The stem also serves as the...

in plants and animals an organ that performs the functions of giving rise to offspring. In many lower plants and in all higher plants the cycles of development involve alternation of nuclear phases, leading to alternation of asexual (sporophyte) and sexual (gametophyte) generations. In such ...
functional modifications in organs are the reduction of eyes in burrowing and speluncar animals, the reduction of stamens in labiates and scrophulariaceous plants, the development of lungs in a number of terrestrial vertebrates, and the well-developed root system of plants that grow in arid ...
