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? there will be interspecific competition between foxes and tigers. there will be intraspecific competition between foxes and tigers. the energy received at the trophic level of carnivores will be less than the usual amount. the energy received at the trophic level of carnivores will be more than the usual amount. there will be decreased biomass at the trophic level of carnivores. need this asap .

The following option are correct:
1. There will be interspecific competition between foxes and tigers.
Competition for food between animals of different species is called interspecific competition while that between the same animal species is called intraspecific competition. 
2. The energy received at the tropic level of carnivores will be less than the usual amount.
The energy received at the trophic level become reduced because the amount of food available for the carnivores has been reduced.
3. There will be decreased biomass at the trophic level of carnivores.
Decrease biomass will occur at the trophic level of carnivores because, those carnivores that can not survive the food reduction problem will die off. 

I’m going to go with b!

Humans can affect weathering and erosion in several ways.  humans cause  increases in acid rain and pollution, which increase the amount of  weathering  agents in the air and water, and then on land.for an easy answer: 1) acid rain2) pollution
