Question

How do spiders and houseflies take in their food?

Answer 1

Put a medium-sized insect in the web of a large orbweaving spider in the garden. ... As a first step in eating, the spider will literally vomit digestive fluid over the prey. Then the prey is chewed with the "jaws" (chelicerae), and the fluid is sucked back into the mouth together with some liquefied "meat" from the prey.

Answer 2

SPIDERS

Spiders belong to a group known as the Arachnids and are found in every region of the world except Antarctica. Spiders have eight legs and two body parts – the cephalothorax and abdomen. Spiders also have jaws called chelicerae that include fang-like appendages at the tip. Some species of spiders have modified mouthparts used for grasping or crushing their prey.

So, what do spiders eat to sustain themselves? Most people are fearful of being bitten by a spider, however, it's important to note that humans are not a food source for spiders. With that said, let's take a look at their preferred food choices.

The food source for spiders depends on the species. Most spiders are predators feeding on insects and even other spiders. It's important to know that most spiders will only feed on live prey or prey that they have recently killed.

HOUSEFLIES


Most flies have mouthparts that are best described as two sponge pads and a straw. Their lips have grooved channels that allow liquid to flow in from the two fleshy pads attached to the fly's lower lip (the labella). Since they cannot chew, flies have to dissolve solid food into liquid, or at least into particles measuring 0.45 millimeters or less. To do this, the fly regurgitates saliva from its stomach, which dissolves the food until it is digestible. The house fly then uses its proboscis to suck up the liquefied food.

Though they eat with their mouths, house flies taste with their feet. This is why they are always crawling on your food. Since they also "taste" spoiled meat and feces, the last place you want them crawling is on food you're about to put in your mouth – not to mention flies constantly defecate.
