An ecosystem is experiencing a devastating drought. It has not rained in weeks. How will the servere lack of rainfall affect the biotic factors in the ecosystem
Drought impacts ecosystem in many different negative ways.
All biotic factors (that is living organisms) in an ecosystem depend on water.
It can also lead to losses or destruction of fish and wildlife habitat.
Lack of food and drinking water for wild animals.
Increase in disease in wild animals, because of reduced food and water supplies.
Drought can lead to increases in wildfire and insect outbreaks, local species extinctions, forest diebacks, and altered rates of carbon, nutrient, and water cycling – all of which can have real consequences for ecosystems and human communities alike
Plants and animals depend on water, just like people. When a drought occurs, their food supply can shrink and their habitat can be damaged.
Sometimes the damage is only temporary and their habitat and food supply return to normal when the drought is over.
