Question

For each statement, select TRUE (1) if it is consistent with the food web presented above, or FALSE (2) if it is not consistent with the food web. 

 

 

If poaching by humans removed many elephants, then the number of wild dogs and lions would decrease. 

 

Reducing the number of species in this food web would likely increase the amount of time it takes this food web to recover from perturbation. 

 

A drastic reduction in the number of snakes due to wildfires would strongly affect mice in this ecosystem. Assume mice are not directly affected by wildfires.

 

If a pesticide was applied to gourds and started to bioaccumulate in them, biomagnification would result in high concentrations of the pesticide in wild dogs. 

 

If a flood removed 50% of ants, then the biomass of pheasants would also decrease by 50%. Assume pheasants are not directly affected by flooding.

 

Ants and mice may be competing for tulips.

Figure 2. This diagram represents the food web of a conservation area in central
Africa based on data collected from 2003 to 2013. The arrows represent feeding
interactions and point towards the consumer. Thicker arrows means more frequent
consumption by the consumer.
