Answer:
Option (B)
Explanation:
A river that is diverted to the irrigating farmland during a drought is an example of the human-caused disturbances to an ecosystem.
An ecosystem refers to a particular community within which the organisms exist and interact with each other. For example, fresh water ecosystem, desert ecosystem and forest ecosystem.
In the given situation, the river channel is disturbed by changing its flow direction. This is caused by the human activity, that changes the course of the river channel to the farmlands during a flood, so that the water can provide nutrient to the soil and prevent the soil from getting eroded.
Thus, by doing this, the river ecosystem gets affected, as a result of which the organisms existing in this ecosystem such as fishes are affected.
Hence, the correct answer is option (B).
Data that shows why floods were occurring , how they were occurring so that they could progress and make changes to the issues.
One very common function of an antenna of an arthropod would be for sensory. It is used by these organisms mainly for touch. Also, other uses would be sensing the motion of air, heat, sound and as well as taste and smell.
Animals contribute water vapor back into the atmosphere by respiring, breathing out water vapors that rise to the atmosphere. They're perspire to prevent overheating; during this process, water is excreted through the pores and evaporates off the skin, cooling the animal by absorbing the external heat.
