Answer: Option C.
Population density is the total number of organisms within a fixed area.
Explanation:
Population density is the total number of organisms per unit area. Population density is calculated by dividing the number of organisms by the unit area either in square kilometers, squaremeters, square miles.
Population density =number of organisms ÷ unit of land area.
Answer:mutualism
Explanation:
In a mutualistic relation,both organisms involved benefit from the activities of each other. The benefits may be nourishment,shelter, protection etc.
In the above example,the birds are known to guide humans by responding to specific calls made by the human. They guide humans to beehives and then in return gets to feed on left over honey. Both the bird and human benefits by getting nourishment.
Mutualism is unlike parasitism where one of the organism involved benefits and the other organisms Is most likely harmed. It is also not commensalism, where one organism benefits and the other neither benefits nor is harmed
The digestive system is greatly affected by the irritation in the small intestine that occurs because of gallbladder disease.
A, B, and C make no sense
A makes no sense because Methane is lighter than air, and so the Methane would stay higher in the atmosphere, so it would not seep into the ground, it would remain in the air.
B makes no sense because Burning fossil fuels causes air pollution by increasing the amount of carbon dioxide in the air. the only way that carbon dioxide could pollute water is if it is combined on a molecular level, plus carbon dioxide does not inhibit the process of water being evaporated by the sun.
C also makes no sense because Deforestation causes acid rain by increasing carbon dioxide not decreasing carbon dioxide in the atmosphere.
so therefore by elimination your answer is D
Answer:
The correct answer is D. interspecific competition
Explanation:
Niche overlap occurs when two species share a same niche and use the same resource. So niche overlap most frequently leads to competition between these two species called interspecific competition.
So In interspecific competition, the individuals of two different species fight for the same resource present in their niche for their survival. For example, lions and leopard share the same niche because they prey on similar types of animals like deer, wild pigs, etc.
So here niche overlap lead to the competition between these two carnivores. In interspecific competition, one species is more successful than other.
