As we know vaccines have been a very controversial topic, and one of them is autism, even when this has been proved false and the original paper where it was published the study retracted, there still a number of people who argue that this is true, even when evidence in favor of vaccine safety is overwelming. Therefore the correct answer is false.
Answer: B) Black bears, deer, and squirrels would undergo a mass extinction, so the forest’s biodiversity would decrease.
Limiting factor is a factor which limit the growth, distribution and abundance of population of one or more species in an ecosystem. A limiting factor can be natural or man-made. Natural limiting factor includes resources (food, shelter and water), abundance in predator population, natural disasters like landslide and earthquakes. Man-made limiting factors include deforestation, forest fires and nuclear explosions.
Here, oak trees can be considered as limiting factor. Oak trees are source of food resource in temperate deciduous forest. Cutting down of these trees will affect the populations of animals residing in the forest. As, populations of beer, black deer, and squirrels all rely on the acorns obtain from oak trees, cutting down of trees will result in mass extinction of black bears, deer, and squirrels. Hence, the diversity of animals in forest would decrease.
