Answer:
the second option is correct.

Deltas are wet lands that form as rivers empty their water and sediments into another body of water such as an ocean, lake, or another river. Deltas can also empty into land although this is less common.
A river moves more slowly as it nears its end. This causes sediment, solid material that has been carried downstream by the water to fall to the river bottom.
The slowing of the river and the build up of sediment allows the river to break up from its single channel to several channels forming a triangular flow at the mouth called a delta.
Answer:
An orange peel in a trash will start to decompose.
- The carbon atoms will be released into the air as a result of decomposition.
- These carbon atoms will be converted into carbon dioxide in the atmosphere.
- Plants will take in this carbon dioxide for making food by the process of photosynthesis.
- When animals will consume the pants, the carbon products will be accumulated int he body of the animals. Some of the carbon will be converted into carbon dioxide in the animals and will pass out of the animal's body through respiration.
