Answer:
See the answer below
Explanation:
1. The data from the experiment shows that <u>as the percentage of salt in the solution used to water the plants increased, the growth rate of the plants decreased</u>. As the percentage increased from A to D, the change between the average initial and the final heights decreased, meaning that an increase in the percentage of the salt in the solution used to water the plants had a negative impact on the growth rates of the plants.
2. Due to the solutions used to water the plants in groups E and F being more concentrated (hypertonic) to that of the cell sap of the plant, <u>water molecules diffused out of the cell sap to the ambient solution</u>. As time goes by, the plants lose too much water, become wilted, and died off eventually. Instead of water molecules to keep diffusing into the plants in order for them to grow, the reverse was occurring and this led to their death.
Mitochondria = known as the powerhouses of the cell.
They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.
Most of the plants are multicellular.
Answer:
The main role of the decomposer in any ecosystem is to recycle nutrients once organisms die and recycle nutrients in waste.
