Solution
(a) The pyramid of energy is upright for any ecosystem. The producers are at the first level and possess high amount of energy. As per the 10% law, there is decrease in the amount of energy with the increase in the trophic level. The primary consumer will have energy less than the producer and go on decreasing with the higher trophic levels.
(b) The process of change in ecological community of an area over time which in turn results in the formation of climax community is termed as succession. Ecological succession is the directional change in the flora and fauna of a given region over a period of time. It is the process of gradual change in the species structure of an ecological community over time.
