The correct answer is - increased competition.
If an ecosystem experiences an increase in its biodiversity, than the result of it would be increased competition. The increased competition will be for food sources, water sources, territory. The reason why increased competition will occur is that there are only limited mounts of food sources, water sources, and territory in the ecosystem. There's also certain amount of niches in the ecosystem, and once all of them are occupied by some species, any other that is specialized for that niche will be competitor plus. This increased competition will lead to high evolutionary pressure, which will result in relatively quick adaptations and specialization in order to survive.
Even being a visual learner the trick is to take notes, even if you never look at the notes ever again its good to write them down, you are more likely to remember something you have written down rather than to just look at it. Science is something that could be easy, you just have to take it at your own pace, don't try to learn science by giving it a quick read or glance at it.
