The scientist who first organized the periodic elements according to its atomic weight was Alexander Emile Beguyer de Chancourtois. He was followed by John Newlands but they both had trouble arranging the properties because of some similarities that came out of the study.
It was Mendeleev who arranged the elements according to the atomic number that made the periodic table properly arranged he also knows that there are more elements that haven't been discovered.

Answer:
<em>Hello, In all the ecological pyramids, producers (organisms that produce their own food) are found at the lowest trophic level. This trophic level contains the highest amount of energy. The energy in each trophic level of an energy pyramid is just 10 percent of the energy in the level below it. (Why is there less energy available at the top of an energy pyramid than at the bottom?) Less energy is available to organisms in the upper levels because each organism releases some of the chemical energy in food to the air as thermal energy. Less total energy is available with each step up energy pyramid. Hope That Helps!</em>
As the new species of plant produced purple flowers, so, the plant belongs to the angiosperms group. Also, the seeds of the plant contain two embryonic leaves, so, the plant must be a dicot.
- Out of all five divisions of plants, only the plants that come under the Division Angiosperm can bear or form flowers. That's why angiosperms are also called flowering plants.
- Angiosperms are further divided into two groups based on the number of embryos that are produced from seeds on germination.
- If the germinating seeds contain only one embryo leaf, then we call them monocots while the seeds that contain two embryo leaves during their developing seeds, then they are called dicots.
Thus, the plant that is discovered by scientists comes under the angiosperm group and further into the dicot group. Dicots have two embryo leaves on germination of their seeds and they also form flowers.
