A recent United Nations analysis report gathered data on declines in biodiversity across the world. Using the graphs provided, which statement shows an area of concern and is an alternative to the general hypothesis "Humans are responsible for a significant increase in the extinction rate among species in the world today as a result of damage caused to the environment"?
A. Fertilizer use in developing countries should be encouraged to decrease the extinction rate
B. Decreasing air pollution in the least developed countries would decrease species survival rate
C. Protection of key biodiversity areas should be a priority for developed countries to lower the extinction rate
D. Assisting developing countries with more sustainable methods of extraction of living biomass would increase species survival rates

- Explain why you chose A or B, etc. Provide a logical explanation defending your answer choice. Q1: Which of the following hypothetical islands would likely have the greatest species richness? Group of answer choices A) Not enough information given B) a small island far from the mainland C) a large island far from the mainland D) a large island near to the mainland E) a small island near to the mainland Q2: Trophic cascades are often caused by Group of answer choices A) climate change B) pollution C) keystone species D) invasive species E) ecosystem engineers F) habitat loss Is my reasoning correct? Or is something wrong with my critical thinking? What do you think? The size of the island and its position is very much crucial for species richness. There are several factors that affect the species richness in a large island near the mainland. A large island near the mainland has the highest species richness which is determined by some…arrow_forwardExplain why you chose A or B, etc. Provide a logical explanation defending your answer choice.

- Why are species that live at the tops of mountains at increased risk of extinction due to climate change? a. The colder temperatures at the tops of mountains gradually increase, and the species at the tops of the mountains are displaced by species at lower elevations moving up. b. The species at the tops of the mountains are adapted to moving up and down the mountains and species at lower elevations are displacing them as they move down the mountains. c. The species at the tops of the mountains are adapted to lower oxygen and climate change increases oxygen content in the air. d. Species at the tops of mountains do not have the genetic diversity for adaptation that lower-elevational species do. Therefore species at the tops of the mountains are more likely to go extinct.arrow_forwardQ1: Which of the following hypothetical islands would likely have the greatest species richness?
