Answer:
Due to the presence of limited number of species.
Explanation:
Bear island provide a great opportunity to decipher entire food chains because this island has many animals species which interact with each other or depend on one another due to the presence of less animals for feeding purpose. This island is isolated from the rest of the world so it provide a great opportunity to study the entire food chains that are present at that island. There is less number of species so knowing about their feeding choices is easier for the ecologists.
Answer:
Regarding wild boar, the fact that is best supported by the evidence provided is wild boars have established successfully mostly in areas with warm climates.
Explanation:
The wild boar (Sus scrofa) is a mammal from Africa, whose capacity to adapt to the environment is high. However, it is usually found in warm climates where it has a good supply of water and food.
According to the description of its distribution on the map, the states where it is found —predominantly Texas, California and Florida— verify the fact that they can be found mostly in warm climates, where they have found an ideal environment for their development..
About the other options:
- <u><em>Wild boars were brought to the United States by humans</em></u><em>. This is true, but it is not a fact that can be deduced from the information on the map.</em>
- <u><em>Wild boars have quickly spread through the United States</em></u><em>. The map does not show this information.</em>
- <u><em>Wild boars have a high reproductive rate and no natural predators</em></u><em>. The map does not show this information.</em>
The correct answer is option (d) atmosphere.
Fossil fuels are the hydrocarbons formed in the geological past, derived from the remains of dead plants and animals. They include the coal, fuel gas and the natural gas. The burning of fossil fuels is one of the greatest contributor of carbon dioxide being added to the atmosphere. This results in the pollution of air in the atmosphere resulting in the formation of smog. Carbon dioxide being a green house gas, affects the atmosphere and causes green house effect leading to global warming and climate changes.
The burning of fossil fuels affects the geosphere, biosphere and hydrosphere indirectly due to its primary direct effect on the atmosphere. Thus, atmosphere is directly affected by the burning of fossil fuels.
