Answer and Explanation:
To test the presence of glucose, we can perform <u>Benedict's test.</u> This test detects the presence of reducing sugars (e.g. glucose) by adding <u>Benedict's reagent.</u> This reagent contains sodium carbonate, sodium citrate and copper(II) sulfate pentahydrate. When the mixture is heated, reduce cupric compounds (Cu2+) are formed which results in the change in color from clear blue to brick-red, yellow or green.
To test the presence of glucose in the food sample, we will dissolve a small volume of food sample in water and put it in the test tubes, in triplicates. Then we will add 3 mL of Benedict's reagent. Also, we will run positive and negative controls. For positive controls, we will add glucose directly and for negative, we will not add any glucose or other reducing sugars (also in triplicates each). Then we will heat the test tubes in water water for 5-10 minutes. In the positive control, the color would change to green, yellow or brick red; but in negative control, it will stay blue (see figure attached for explanation). For the food sample, if the glucose or reducing sugars would be present, the color will change. In case of low sugar, it will be green, but increasing sugar content would change the color to yellow/orange and red. Because the experiment will be conducted in triplicates, we would be also able to verify if the results were consistent and there was no human or technical error.
Fungi do not occupy one specific level of a food chain, but because they are decomposers, they have an effect on every living thing in an ecosystem.
<h3>Fungi:</h3>
Kingdom A group of organisms known as fungi play a significant role in an ecosystem and share a number of distinctive traits. Mold, yeast, and mushrooms are some types of fungus.
An organism known as a decomposer consumes the nutrients found in decaying or dead stuff by breaking it down. The plants and animals that stand in for the various trophic levels in an ecosystem are broken down by fungi. Despite sharing some characteristics with plants, such as emerging from the ground, fungi are not autotrophs. This implies that, unlike autotrophs, fungi cannot manufacture food through the process of photosynthesis and instead must obtain nutrients from their surroundings.
Fungi are heterotrophic as a result. However, unlike other species, they are unable to hunt and consume their food. To do this, fungi cling to organic material and exude digestive enzymes that break down the material. The fungi can then take up the nutrients and release organic molecules that can be recycled back into the soil. Decomposers are crucial components of an ecosystem for this reason.
