Answer #1

◆ Answer :-【 A 】 an increase in primary producer in the ecosystem .

◆ Explaination :-  

  • In general , higher the tropic level , the lower the biomass so the lowest the tropic level has the greatest biomass and these are the producers which include things like tree , grasses etc.
  • Since biomass is the amount of living organic matter present in a ecosystem , so the producer have greatest biomass since they performed photosynthesis . In an ecosystem, biomass decreases from producer to consumer level.
  • For example in an grassland ecosystem producers i.e 1st tropic level has the greatest biomass .

2. Before the 1960s, most ecologists thought that the number of producers in an ecosystem was the only variable that limits the number of herbivores. The idea was that every level was regulated by the amount of food from the trophic level below it. How did the green world hypothesis differ from this “bottom-up” view? 3. Imagine a simple food chain: Grass -> Grasshoppers -> Mice. If snakes that eat mice are added to the ecosystem, how would you redraw...
