Structural Organisation Of Animals And Plants

Cockroach is more active in summer and is nocturnal i.e., comes out of its hiding places at night to feed. It remains concealed in crevices and under various objects during the daytime. It is omnivorous, taking all types of animal and vegetable foods, paper, cloth, leather and dead bodies of animals, even of its own fellows.

Metathoracic or hindwings are thin, membranous, transparent, broad, delicate and are used in flight. They are kept folded like a fan under the tegmina, when at rest. Movements are due to special muscles attached to wing bases which work at a very high speed.

Vermicompost is a heterogeneous mixture of decomposing vegetable or food waste, bedding materials and vermicast. Vermicast, also called worm casting, worm humus or worm manure is the end product of the breakdown of the organic matter by earthworm. These castings have been shown to contain reduced levels of contaminants and a higher saturation of nutrient than do organic materials before composting. Vermicompost containing water soluble nuterients is an . excellent nutrient rich organic fertilizer which is a better alternative to chemical fertilizers as it does not affect soil pH and maintains soil fertility for years without affecting the food quality.

An antenna is made up of many segments which are called podomeres. The antennae can be moved in all directions. They possess sensory. bristles, which are tactile in nature. With the help of antennae, the cockroaches can detect the presence of food and the object in front. Antennae also respond to smell.
