Alyssa observed a flock of small birds in her yard. The birds visited a pair of feeders that her parents put out for them and splashed in the birdbath. Which question is a nonscientific question that she might ask about the birds? What color are the beaks of the small birds that visit the feeders? Does having a birdbath present affect the feeding habits of the birds? At what time of day do the most birds visit the feeders? Would the birds still visit if the seed in the feeders was changed?

not sure if this is what you'r looking for eubacteria and archaebacteria

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.

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
