Answer:
C) Most fungi get their nutrients by ingesting small pieces of other living organisms.
Explanation:
Most fungi are saprotroph, it is, they obtain nutrients by decomposing non-living organic matter -i.e. dead plant or animal matter- and absorbing soluble organic compounds; carbohydrates are the preferred carbon source.
A smaller percentage of fungal species are parasites, and obtain nutrients from living hosts (other living organisms).
In the stomach, food undergoes chemical and mechanical digestion. Peristaltic contractions (mechanical digestion) churn the bolus, which mixes with strong digestive juices that the stomach lining cells secrete (chemical digestion). As food travels from your mouth into your digestive system, it's broken down by digestive enzymes that turn it into smaller nutrients that your body can easily absorb. This breakdown is known as chemical digestion.
Loss of biodiversity matters because it affects the overall sustainability of organisms in an ecosystem. It also affects how badly an ecosystem will be affected after something, maybe a natural disaster, or maybe a disease, strikes the region. (For example, if a disease affects a certain species of organism, if there was a lot of biodiversity among individuals, some will have some kind of natural immunity to that disease and survive, passing on their favorable traits to the next generation. However, if everybody was the same and did not have the immunity to that disease, that entire population would eventually die out.) <- This is also the reason that lack of biodiversity will inhibit natural selection.
Hope that helped you.
