Please please ASAP help me ..Will mark Brilliantest

Alex poured some pond water into three beakers. She then put waterweed into each beaker. She put the beakers in different places.


b. In the school pond there were lots of water lilies with large leaves covering the surface. There were not many plants growing below the surface. Suggest a reason for this.

Answer 1

The most likely reason for this is because they don’t get any sunlight causing plants not being able to grow if there are plants covering the water. There will most likely be plants that are small and can get sunlight from the spots that show sunlight. But overall it will most likely be due to not enough sunlight and probably oxygen.

Answer 2

Answer:
The growth of waterweed plant is higher in beaker E.

Step-by-step explanation:
The growth of waterweed plant is higher in beaker E because the waterweed absorb nutrients that is provided in the form of fertilizers. Fertilizers are the nutrients that is essential for the growth of plants. Those plants that has more nutrients available can grow faster than those plants which have no nutrients or less nutrients because these nutrients provides raw material for the formation of amino acids and enzymes that contributes in the growth and development of the body.
