Nematodes The phylum Nematodes also known as roundworms are one of the most common phyla of animals. There are over 20‚000 different species of roundworms. Roundworms can be found in water‚ and on land. Roundworms have a complete digestive system with two separate openings one for food and one for getting rid of waste. This type of digestive system is very common in complex animal. Nematodes use external and internal pressure and body movement to move food through their digestive tracts

Specifically‚ we quantified belowground biocontrol activity using an in-situ insect baiting technique and assessed soil pH‚ moisture‚ cation exchange capacity‚ soil organic matter‚ % C‚ % N‚ NH4-N‚ NO3-N‚ microbial biomass-N‚ P‚ K‚ Ca‚ Mg‚ and parameters of nematode community. We hypothesized that belowground biocontrol activity will be positively correlated with soil chemical and biological parameters that promote soil health. We found that the potential belowground biocontrol service was high with mean total

to the nematode parasites in the soil. The Lactococcus lactis produces a crystal protein that‚ when ingested‚ can cause death for the parasites. These Cry proteins have been used as crop insecticides in the past. Some of the nematode species are used to control insect pests as well. The introduction of Lactococcus lactis would no undoubtedly decrease the number of nematode species in the affected area. In turn‚ this would also lower the nematodes affect as a pest controller. If the nematode species

conclusions previously based on comparative morphology and fossil records. Hypothesis: One hypothesis is that arthropods evolved more recently from an annelid like ancestor then a nematode ancestor because of their similar body plan and segmentation. The other hypothesis is that arthropods evolved more recently from a nematode ancestor than an annelid like ancestor because of their shared ecdysis trait.

Sponges are in the phylum Porifera. This group is now known to be polyphyletic‚ and all sponges belong to either phylum Calcarea or phylum Silicea. They are the simplest animals and lack true tissues. Label the following: pores‚ spongocoel‚ epidermis‚ amoebocytes‚ choanocyte‚ flagellum‚ spicules

The Flatworms are more than 20‚000 species collectively whereas appreciation that nematode species are about one million and they have been completed descriptions from 28‚000 species. Flatworms are generally larger compared to roundworms in their body size. The largest member of the flatworms is about five centimeters long‚ but the average
