Most seeds eaten by birds and insects

Planting seeds can be a major waste of time and money, since the insects and birds are very aggressive in eating them. A large number of seeds were sown, yet almost no plants have grown in the last one month.
The seeds are germinating and then the top of the seeds is eaten off, effectively killing it.
A lot of money was spent purchasing these seeds, and now there are almost no plants growing. The insects and pests are only not interested in morning glory seeds.
