Q3.13. in our simulation of herbivores feeding in a farm pasture, we treated each species as if it were foraging all by itself. of course, in real ecosystems, there are many different herbivores, some of which compete with one another for food. if both sheep and grasshoppers were feeding in a pasture, how do you think the grasshoppers would affect sheep? choose the best answer.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
