What is an example of parasitism, commensalism, and mutualism in the American grasslands?:p

[llink13]

I have a biome project due tomorrow and I have had some trouble finding the info on the savanna grassland and parasitism/comensalism in that biome

[llink13]

Can you help with this?
I can't find the types of parasitism in the grassland? I can' t find it anywhere!

[llink13]

Wait I'm confused about this place

[llink13]

I'm asking questions for my project and it shows up as a answer

Yes same! I heard one for mutualism... it's for ants and alphides the both benefit from the other.

Abstract: The landscape of the Great Plains has been greatly altered by human activities in the past century, and several grassland passerines have experienced significant population declines in recent decades. We explore here whether brood parasitism by Brown-headed Cowbirds, which are abundant in the Great Plains, has contributed to these declines. We measured the frequency of cowbird parasitism of passerine species in seeded grassland, natural grassland, and cropland in studies conducted in North Dakota during 1981-1993. The proportions of parasitized nests were 25%, 34%, and 39% in seeded grassland, natural grassland, and cropland, respectively. We speculate that much of the variation in parasitism rate among these habitats is related to the local abundance of cowbirds, to nest visibility, and to the presence of suitable perches for female cowbirds. Local abundance of cowbirds may be high in areas with cattle pastures. Nests and nesting behavior are probably more visible to female cowbirds in cropland than in grassland. Female cowbirds may use shrubs as perches while searching for host nests, and shrubs are more common in natural grasslands than in the other habitats we examined. Experimental work on the determinants of cowbird abundance in grasslands is needed.

Example for parasitism the mosquito sip the blood of a human and the human is harm while the mosquito benefits.

Lol I also have a project but it isn't due tomarrow... but I need something other than An oxpecker rests on a African Buffalo picking off parasites while the Buffalo allows the oxpecker rest on him. I hope that helps.
