Question

(6) eagles eat rabbits.
(a) mutualism
(b) commensalism
(c) predation
(d) parasitism
(7) bacteria in the human intestine makes vitamin b and k for the human. the intestine provides a home and nutrients for the bacteria
(a) mutualism
(b) commensalism
(c) predation
(d) parasitism

Explanation:

• For (6):
• Predation is a biological interaction where one organism (the predator) kills and eats another organism (the prey). Eagles (predator) eat rabbits (prey), so this is predation.
• Mutualism is a relationship where both species benefit. In (6), only one species (eagle) benefits from killing and eating the other (rabbit), so it's not mutualism.
• Commensalism is a relationship where one species benefits and the other is neither helped nor harmed. Since the rabbit is killed (harmed), it's not commensalism.
• Parasitism is a relationship where one organism (parasite) lives on or in another organism (host) and harms it but usually does not kill it immediately. Here, the eagle kills the rabbit, so it's not parasitism.
• For (7):
• Mutualism is correct. The bacteria make vitamins (benefit for human) and the intestine provides a home and nutrients (benefit for bacteria).
• Commensalism is incorrect as both species are benefited, not just one.
• Predation is incorrect as there is no killing and eating of one by the other.
• Parasitism is incorrect as neither organism is harming the other in a parasitic way; both are benefited.

Answer:

(6) c. predation
(7) a. mutualism
