Base your answer to the question on the information below and on your knowledge of biology.

a student designed an experiment to determine if the air temperature had an effect on the rate of photosynthesis in corn plants.

the independent variable in this experiment is the:

a) air temperature at which the corn plants were grown

b) amount of carbon dioxide used by the corn plants

c) volume of oxygen produced by the corn plants

d) number of corn plants used

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.

b. climate change will cause an increase in biodiversity of all ecosystems.

hope this

i think the answer is composed of atoms
