B. Gradualism
"Gradualism is an evolutionary model that refers to the tiny variations in an organism or in society that happen over time to make a better fit for animals and humans in their environment. These variations allow them to survive and thrive, resulting in the slow and consistent process of change in the whole population."
Answer:
A plant cell has a cell wall for support and protection
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.
