I believe that B and D are the only answers that I am sure of. C is incorrect and A seems incorrect as well. E may be a correct answer, but you will need to check the chemical equation. Hope this helps!
Applying ice to a fire victim leads to tissue hypoxia and necrosis because it will change the skin's temperature too fast and may cause frostbite. The burn could have had removed a layer of skin, leaving the fragile tissue exposed which will be more sensitive to the ice.
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.
