Niche/ecological niche is specific part of habitat occupied by individuals of a species which is circumscribed by its range of tolerance, range of movement, microclimate, type of food and its availability, shelter, type of predator and timing of activity. A habitat has several ecological niches and supports a number of species. An ecological niche is used by a single species. Two or more species cannot use the same niche despite having a m u tu a listic a sso c ia tio n . O rg an ism s or populations in competition have a niche overlap of a limited resource for which they compete. Both owl and cat feed on shrews and mice. They occupy the same niche because of being ecological equivalents though their habitats are different.

Spinning Process of Silkworm Larva
The silkworm larva goes through a fascinating transformation when it is ready to spin its cocoon. During this stage, the larva stops eating and starts producing silk around its body. This process is crucial for the production of silk, which is a highly valuable and sought-after material.
Direction of Spinning
The silkworm larva spins the silk from inside to outside. This means that the silk thread is produced from glands inside the body of the larva and is then extruded through spinnerets located near its mouth. As the silk comes out, it solidifies upon exposure to air and forms the cocoon around the larva.
Importance of Inside to Outside Spinning
Spinning the silk from inside to outside allows the silkworm larva to create a protective and sturdy cocoon. The silk thread is evenly distributed around its body, forming a strong and secure structure that will protect the larva during its metamorphosis into a moth. This process ensures that the silk produced is of high quality and can be harvested effectively for various purposes.
In conclusion, the silkworm larva spins silk from inside to outside in a precise and efficient manner to create a cocoon that serves as a protective covering. This natural process plays a significant role in the production of silk, which has been valued for centuries for its luxurious texture and versatility.
