Using what you learned about ecological interactions think of an example of each interaction in which humans are involved

a. Competition: Humans compete with all organisms for space.

b. Parasitism: Humans have many parasites: head lice, ticks, tapeworms, etc.

c. Mutualism: We have mutualistic relationships with all domesticated plants/animals.

d. Commensalism: Pigeons thrive in metropolitan ecosystems without really

affecting humans (except for being mildly disgusting).

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
