Explanation:

To solve this problem, we analyze each seed - dispersal scenario based on the given images and descriptions:

1. For the elephant - tree image:

Step 1: Identify the dispersal agent

The elephant is near the tree. Elephants (and other animals) can eat fruits with seeds.

Step 2: Describe the dispersal process

When an elephant eats the fruits of the tree, the seeds pass through its digestive system and are later excreted in a different location, which helps in seed dispersal. So a possible sentence is: "An elephant eats the fruits of the tree, and the seeds are dispersed in its droppings."

2. For the dandelion - boy image:

Step 1: Identify the dispersal agent

The boy is blowing the dandelion. The dandelion seeds are very light and have structures that allow them to be carried by the wind.

Step 2: Describe the dispersal process

When the boy blows the dandelion, the seeds are carried away by the wind to new places. So a possible sentence is: "A boy blows a dandelion, and its seeds are carried away by the wind."

3. For the pod - seeds image:

Step 1: Identify the dispersal mechanism

The pod is opening, and seeds are being released. This is a case of self - dispersal (explosive dispersal) in some plants.

Step 2: Describe the dispersal process

The pod of the plant dries up and bursts open, and the seeds are scattered away from the parent plant. So a possible sentence is: "The pod of the plant bursts open, and the seeds are scattered."

Answer:

s for each part:

• For the elephant - tree: "An elephant eats the fruits of the tree, and the seeds are dispersed in its droppings."
• For the dandelion - boy: "A boy blows a dandelion, and its seeds are carried away by the wind."
• For the pod - seeds: "The pod of the plant bursts open, and the seeds are scattered."
