In grasslands, goats are prey for both foxes and tigers. if the population of goats decreases because of natural causes, what are three possible consequences?

1. There will be inter specific competition between foxes and tigers.

2. The energy received at the tropic level of carnivores will be less than the usual amount.

3. There will be decreased biomass at the tropic level of carnivores. Decrease biomass will occur at the tropic level of carnivores because, those carnivores that can not survive the food reduction problem will die off

Explanation:

Competition for food between animals of different species is called inter specific competition while that between the same animal species is called transpacific competition. 

The energy received at the tropic level become reduced because the amount of food available for the carnivores has been reduced.

Decrease biomass will occur at the tropic level of carnivores because, those carnivores that can not survive the food reduction problem will die off. 

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion
