As heterotrophic organisms, nematodes are ultimately dependent on autot- rophic organisms for their energy supply, but it is the plant disease and crop loss aspects of the relationship that have developed into “plant nematology” (e.g., Dropkin, 1980; Southey, 19.78).
Nematode, also called roundworm, any worm of the phylum Nematoda. Nematodes are among the most abundant animals on Earth. They occur as parasites in animals and plants or as free-living forms in soil, fresh water, marine environments, and even such unusual places as vinegar, beer malts, and water-filled cracks deep within Earth’s crust.
They are very small and can be microscopic. However, some can measure up to one meter long. Like many other organisms in kingdom Animalia (also referred to as metazoa) nematodes are eukaryotic, multicellular organisms that obtain nutrients from organic sources. Nematodes/roundworms make up the phylum Nematoda.
Nematodes exist as free living organisms in terrestrial and aquatic environments or as parasites of both plants and animals. Some of the worms belonging to the phylum Nematoda include: Some of the general characteristics of roundworms include: They are very small and can be microscopic. However, some can measure up to one meter long.
Are nematodes herbivores?
Many nematodes, both herbivores and carnivores, feed by inserting a rigid “stylet” into their food source—in some the stylet is hollow and acts as a drinking straw. Others feed by “gulping” a food particle whole through a mouth opening. They may have rasping/crushing “teeth” within the pharynx – or not.
Are nematodes only terrestrial?
With well over 15,000 species identified today, they can be found in different habitats ranging from terrestrial to marine environments. Nematodes exist as free living organisms in terrestrial and aquatic environments or as parasites of both plants and animals.
Are nematodes parasitic or free living?
Nematodes do not decompose organic matter, but, instead, are parasitic and free-living organisms that feed on living material.
How are nematodes classified?

Do plants eat nematodes?
Plant-eating nematodes: A threat to root crops After the cells are broken down, the nematodes eat up this soup [2]. When nematodes feed on carrot roots during the early stages of the plant’s life, this can cause serious damage or even the plant’s death.
What fungi eat nematodes?
Nematophagous fungi can adopt a carnivorous lifestyle, during which they eat nematode worms. To do so, the cells organize themselves to form nets that trap nematodes, which are subsequently digested by the fungus.
Do nematodes eat nematodes?
Predatory nematodes eat all types of nematodes and protozoa. They eat smaller organisms whole, or attach themselves to the cuticle of larger nematodes, scraping away until the prey’s internal body parts can be extracted.
How do I get rid of nematodes in my soil?
To kill nematodes in soil, heat small quantities of moist soil to 140°F in the oven or by solarization. Heating soil in the oven over a time period needed to bake a medium-sized potato placed in the center of the soil is sufficient to kill nematodes; however, this is only practical for small quantities of soil.

Heterotroph Definition. A heterotroph is an organism that cannot manufacture its own food by carbon fixation and therefore derives its intake of nutrition from other sources of organic carbon, mainly plant or animal matter.

Autotroph Vs Heterotroph: The Difference | Science Trends
The difference between an autotroph vs. heterotroph lies in the organism’s ability to either produce its own food or need to ingest food. Autotrophs, such as plants, can produce their own food from light via photosynthesis or chemicals via chemosynthesis. Heterotrophs, such as humans, require ingesting food in order to produce energy and thus are not self-sustaining as plants are.
