Answer: B: the variety of living things on Earth.
(Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.)
Answer:
<em>The correct option is B) Freshwater snails and small fish</em>
Explanation:
As we can see from the food web, the fresh water snails and the small fishes both feed on algae and water plants as their source of food hence, both these organisms feed on the same food.
Other options, like option C, is not correct because water boatman and water plants do not feed on the same sources. Water boatman feeds on reeds whereas water plants do not. Water plants will make their own food.
Let's just say that everyvyear, many people either get the vaccination, or the flu. These people are left immune to the strain of flu that they were vaccinated/infected with so the number of people who can get and pass on that form of flu (think of these people as that flu strain's "habitat") is reduced. If some of that flu mutates sufficiently that the immune systems of those previously infected vaccinated people no longer recognize it, then it's habitat is expanded back to the original size again.
Hope this helped :)
Have a great day
The DNA molecule is shaped like a ladder that is twisted into a coiled configuration called a double helix. The nitrogen bases form the rungs of the ladder and are arranged in pairs, which are connected to each other by chemical bonds.
