Question

Nutrition in spiders?? explain in 10 lines..​

Answer 1

Answer:

Spiders represent a diverse, widespread and abundant group of carnivores. Studying the nutritional ecology of spiders is critical because it can aid in understanding the evolution of prey capture and life history strategies, factors regulating the abundance and diversity of spiders in particular habitats and the role of spiders in arthropod community dynamics including biological control of crop pests. The feeding habits of spiders have long attracted the attention of biologists, in part, because many build webs and are relatively easy to observe. While these studies have provided a wealth of information on the abundance and types of prey captured, they have yielded relatively little information on the types and quantities of nutrients ingested by spiders in nature. Relatively little is also known about the nutritional requirements of spiders, although recent studies using more controlled manipulations of prey nutrient content are beginning to provide a clearer understanding of the types and quantities of nutrients needed by spiders to maximize performance. There is a tremendous opportunity to rapidly advance our understanding of spider nutrition, given a strong foundation in the natural history, behaviour, physiology and ecology of spiders and recent advances in analytical techniques and frameworks for studying nutrition.

Explanation:

$\huge \mathbb \fcolorbox{black}{pink}{ANSWER:}$

Spiders feed using extraoral digestion (Cohen, 1995). This process involves injecting enzymes into prey, waiting for the enzymes to liquefy nutrients and then sucking nutrients out of the prey (Cohen, 1995.
