Options

B. Their feathers
C. Carrying seeds in their beaks
D. Eating fruits and digestive fruit contents in their alimentary canal .

Answer

**Step-by-Step Solution:**

1. **Understanding Seed Dissemination**: Seed dissemination refers to the process by which seeds are spread away from the parent plant to new locations where they can germinate and grow.

2. **Role of Birds in Seed Dissemination**: Birds play a significant role in this process. They consume fruits that contain seeds, which is a primary method of seed dispersal.

3. **Eating the Fruit**: When birds eat fruit, they typically consume the pulp of the fruit, which is often rich in nutrients and attractive to them.

4. **Passing Seeds Unharmed**: As the birds digest the fruit, the seeds inside the pulp move through their digestive system. Importantly, many seeds have a tough outer layer that protects them from being digested.

5. **Excretion of Seeds**: After the seeds have passed through the bird's digestive system, they are excreted along with the bird's droppings. This process allows the seeds to be deposited in new locations.

6. **Nutrient-Rich Environment**: The excreta of birds is often rich in nitrogen and other nutrients, which can provide a beneficial environment for the seeds to germinate and grow.

7. **Conclusion**: Therefore, the correct answer to the question "Birds disseminate seeds by" is: **eating fruit and passing the seeds unharmed through excreta at places**.
