When humans farm large plantation of one cash crop, they reduce the biodiversity of the region because they reduce the genetic diversity of the species in the environment. A reduction in genetic diversity means that the genetic variability of the species is reduced hence there are fewer sub-species in the environment. This ultimately reduces the biodiversity of the ecosystem - which is the variability among all the living organisms in the environment.
Answer: Experience 1 is the one that has the greatest reliability.
Explanation: Because of this potential variation, biological experiments need to have a large sample size and preferably be repeated several times. With more samples and repeating the experiment more often, the probability of arriving at a wrong conclusion due to random variation is diminished. As experience 1 has had several repetitions, it is the experience with a more reliable result.
Answer:
The correct answer is - option 3.
Explanation:
The given options are the question are affects the protection of the ecological system in one or another manner but the mandating the rights of government sale of the logging rights in a national forest must be a proper and fair market value.
This will lead to a decrease in the illegal sale of logging sale which results in maintaining the ecological system in the national forest.
Thus, the correct answer is - option 3.
