Answer:
1. Plants utilize some of the incoming energy derived from photosynthesis for their own self-maintenance.
3. Plants and algae carry out both photosynthesis and cellular respiration.
5. Plants, algae, and cyanobacteria utilize light energy from the sun into their own biomass.
Explanation:
The gross primary productivity (GPP) of an ecosystem represents the rate at which the solar energy is captured during photosynthesis in a given period. Producers (plants, algae and cyanobacteria) perform cellular respiration to provide energy for their life processes. Cellular respiration consumes part of the total photosynthetic output. The energy available in tissues of producers after cellular respiration is called net primary productivity (NPP).
Therefore, NPP is the amount of biomass or the energy stored in the tissues of the producers for growth after cellular respiration for their normal daily activities and self-maintenance. So, NPP is always less than GPP.
Answer:
In 2020 renewable energy sources produced more electricity than all fossil fuels (coal, gas, oil) together and now provide 45.3 percent of German electricity demand.In July 2019, figures published by the Fraunhofer Institute for Solar Energy Systems (ISE) report that renewable energy is for the first time providing more electricity than coal and nuclear power combined in Germany. Solar, wind, biomass and hydroelectric power generates nearly half of the country's output.

Answer:
long DNA
Explanation:
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. Most eukaryotic chromosomes include packaging proteins called histones which, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity.
