Considering environment and ecosystem, identify the INCORRECT statement

#10. Ecological Principles
  1. In detrital food chain, it is very difficult to measure the energy flow although the use of radioactive tracers give some idea about the energy flow
  2. The change in species composition, community structure and function over time is ecological succession
  3. The slower rise of environmental temperature may be attributed to the increase in pollution in environment which reflects enough solar energy back to other spacer to slow down global warming
  4. Photoperiodism has no relation with the environment and ecosystem, rather it is a biological event taking place in every plant
