Gary is using several charts and tables to learn about patterns of migratory birds. Which information reference is he most likely using? a. Atlas c. Encyclopedia b. Almanac d. None of these Please select the best answer from the choices provided A B C D.

a. the production of carbon dioxide through the process of photosynthesis

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

several tissues working together form an organ, and several organs together make up an organisms.

the group of cell that carries out special jobs are tissue.
