    #5 Which of the following best explains the natural cause of a decrease in biomass as succession peaks in a climax community? Select one: a. Once a climax community is reached, there are no nutrients left in the ecosystem to support the growth of plants. b. The canopy of forests prevents sufficient light from reaching the forest floor, thereby limiting primary productivity. c. Humans usually cut down old growth forests. d. The presence of large animals such as elk or wolves prevents the development of young animals.

    i dont wanna give direct answers but ill try to explain, primary succession is the colonization of new plants on a previously uninhabitable area. an example could be algae growing on cooled volcanic rock. secondary succession is when most of the area is wiped out but there is still enough nutrients for the area to regrow life. example could be after a forest fire and the forest slowly regrowing. this should help with 1-4 5, my choice would be B because after those tall trees have grown not as much sunlight can reach the floor so the plants on the bottom wouldn't receive as much nutrients you can probably guess 6...
