The correct question will be :
• What will happen if crow is absent in an ecosystem?
It leads to following changes if a crow is absent in an ecosystem :

What if crow is absent on an ecosystem
Crows live in an area where people live and reach the greatest number in dense human settlements, where there is ample access to garbage, grain and livestock. On the other hand, they are absent where there are few or no people, for example in deserts and dense forests.
The close association of domestic crows with humans often leads them to become pests when numbers increase due to food theft, damage to crops and livestock, noise, and possible health risks from environmental contamination. Habitat, and are severe predators of native birds to the extent that control programs are carried out in many places, generally with limited success.
Crows are predators and scavengers, which means they eat pretty much everything. Their diet consists of various street killers, insects, frogs, snakes, mice, corn, human fast food, even eggs and chicks from other birds.
Due to the decrease in the number of crows in the ecosystem leads to an increase in the number of predators, and there will be fewer scavengers .
