Because they need it to get protein and create it. Protein helps the plants grow.
Starch and cellulose are two very similar polymers. In fact, they are both made from the same monomer, glucose, and have the same glucose-based repeat units. There is only one difference. In starch, all the glucose repeat units are oriented in the same direction..
Hope this helped :)
Answer:
The energy that Earth receives from sunlight is balanced by an equal amount of energy radiating into space. ... When the flow of incoming solar energy is balanced by an equal flow of heat to space, Earth is in radioactive equilibrium, and global temperature is relatively stable
Explanation:
A balance between incoming and outgoing radiation produces a steady-state and stable global climate. Lack of a balance between incoming and outgoing radiation implies a net loss or net gain of radiant en- ergy to Earth's climate system.
Answer: Estuaries
Explanation:
Estuaries are areas where freshwater streams or rivers merge with the ocean. This mixing of waters with such different salt concentrations creates a very interesting and unique ecosystem. Microflora like algae, and macroflora, such as seaweeds, marsh grasses, and mangrove trees (only in the tropics), can be found here.
