Answer:
It might have animals that depend on this "animal" for a food source. If we were to remove it, all the animals that are after this "animal" on the food chain will die out and the animals that they eat will over populate.

Roundworms or nematodes<span> constitute the phylum Nematoda. They are a diverse </span>animal phylum inhabiting a broad range of environments. The most essential representative for this group is the <span>Bursaphelenchus xylophilus. Hope this answers your question. Have a great day!</span>
I think they are all biotic factors..hmm if not take out whichever sounds the most not fitting.
<span>Notice a couple of things
different between (A) and (B). It was NOT the first time a biologist
proposed that species changed through time (so it's not B). But it
finally *solidified* that idea by giving "change through time"
(evolution) a MECHANISM. It gave a plausible explanation for WHY
species change over time, in a testable way that made sense and had
evidence to support it.
So it finally dismissed the idea that species are constant.
It also emphasized that the simple presence of *variation* within a population was a key reason for evolution.
While we're at it ... (C) is wrong because it's not *individuals* that
acclimate (adapt) to their environment, but the population (the species)
as a whole.
And (D) is wrong because it had nothing to do with economics or the monarchy.</span>
