Why do high altitude areas have brighter sunlight and lower temperatures as compared to the plains?
At high altitude the sun light is brighter as compared to plains, it is because of reduced distance from the sun and particles free air. Similarly lower temperatures are because of lower atmospheric pressure which is more in plains as compared to high altitude.
What is homeostasis?
Homeostasis is the tendency of the organism to maintain a constant internal environment despite varying external environmental conditions like temperature.
Define aestivation.
Aestivation is a behavioural adaptation to avoid extreme heat and dessication in summer season. In which the organism slows down its metabolic activities.
It is also known as summer sleep.
What is diapause and its significance?
It is a stage of suspended development that some organisms like zooplanktons in lakes and ponds, adopt to survive under unfavourable conditions.
What would be the growth rate pattern, when the resources are unlimited?
In case of unlimited resources, the pattern of growth rate is exponential.
