Describe the interactions between organisms within an ecosystem. Give an example of a specific relationship that organisms may have, and how this relationship affects the ecosystem.

Predation: One Wins, One Loses. Predation includes any interaction between two species in which one species benefits by obtaining resources from and to the detriment of the other.

Competition: The Double Negative. Competition exists when multiple organisms vie for the same, limiting resource.

Mutualism: Everyone Wins. Mutualism describes an interaction that benefits both species.

Commensalism: A Positive/Zero Interaction. An interaction where one species benefits and the other remains unaffected is known as commensalism.

Amensalism: A Negative/Zero Interaction. Amensalism describes an interaction in which the presence of one species has a negative effect on another, but the first species is unaffected.

Explanation:

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

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.
