Please help!!!!


a) explain how each of the following three ecological disruptions would affect the number and size of trophic levels in an ecosystem:


i. decrease in the available sunlight


ii. increase in the number of producers


iii. increase in the availability of a resource that was limiting the herbivore population size


b) describe the concept of trophic efficiency

Respuesta :

Answer:

i. with decrease of sunlight means less photosythsis which lead to decrese in plant growing crop and other food .

2 more  number of producers mean excess of food as  they more producers  then consumers

3  increase in the herbivour population  size by either reproduction nor migration from different area then after some time the food supply will decrease in the surrounding area .

d Trophic efficiency The ratio of production at one trophic level to production at the next lower trophic level. is calculated by the percentage of energy that consumers in one trophic level gain and convert into biomass from the total stored energy of the previous trophic level.
