Why is the interdependence of the worms and plants an example of commensalism?
The interdependence of worms and plants is an example of commensalism because the worms benefit from the nutrients provided by the plants, while the plants are neither harmed nor benefited by the presence of the worms. What are the three types of symbiotic relationships?
The three types of symbiotic relationships are mutualism, commensalism, and parasitism. Which of the following best describes a symbiotic relationship? A) Both organisms benefit B) One organism benefits, the other is unaffected C) One organism benefits, the other is harmed D) All of the above
D) All of the above Which of the following is an example of symbiosis? A) A lion hunting a zebra B) A bee pollinating a flower C) A tree providing shade D) A rock in a river
B) A bee pollinating a flower How is parasitism different from commensalism?
Parasitism differs from commensalism in that parasitism benefits one organism while harming the other, whereas commensalism benefits one organism without affecting the other. Which is not one of the 3 forms of symbiosis? A) Mutualism B) Commensalism C) Parasitism D) Competition
D) Competition In which type of interaction do both species benefit?
In mutualism, both species benefit. Which of these are symbiotic associations? A) Mutualism B) Commensalism C) Parasitism D) All of the above
D) All of the above What is the type of symbiotic relationship where only one species benefits?
Commensalism is the type of symbiotic relationship where only one species benefits. In which type of relationship do both species always benefit?
In mutualism, both species always benefit. What type of symbiotic relationship would an orchid and the tree it is living on share?
An orchid and the tree it is living on share a commensalistic relationship. What are two types of symbiotic relationships in plant roots?
Two types of symbiotic relationships in plant roots are mutualism and commensalism. Which is not a form of symbiosis? A) Mutualism B) Commensalism C) Parasitism D) Predation
D) Predation Which one of the following relationships is not an example of symbiosis? A) A bee and a flower B) A lion and a zebra C) A remora and a shark D) A fungus and an alga
B) A lion and a zebra Which scenario describes a relationship of commensalism?
A scenario where a remora fish attaches to a shark and feeds on its leftovers describes a relationship of commensalism. Which scenario describes a relationship of mutualism?
A scenario where a bee pollinates a flower while collecting nectar describes a relationship of mutualism. Which of the following is not an example of symbiosis? A) A bird cleaning a crocodile's teeth B) A tick feeding on a dog C) A wolf hunting a deer D) A lichen on a rock
C) A wolf hunting a deer Which benefit do intestinal bacteria gain living in a mutualistic relationship with an animal?
Intestinal bacteria gain nutrients and a suitable environment for growth in a mutualistic relationship with an animal. In which of the following relationships is neither species harmed? A) Mutualism B) Commensalism C) Parasitism D) Competition
B) Commensalism Which of the following is a symbiotic relationship in which both organisms benefit? A) Parasitism B) Commensalism C) Mutualism D) Competition
C) Mutualism How is commensalism different from parasitism?
Commensalism differs from parasitism in that commensalism benefits one organism without affecting the other, while parasitism benefits one organism at the expense of the other. Which of the following can be involved in mutualistic relationships with plants? A) Fungi B) Bacteria C) Insects D) All of the above
D) All of the above Which statement is an example of mutualism?
An example of mutualism is when bees pollinate flowers while collecting nectar. Which of the following are types of symbiotic relationships? A) Mutualism B) Commensalism C) Parasitism D) All of the above
D) All of the above What is mutualism in the context of community interactions?
Mutualism is a community interaction where both organisms benefit from the relationship, making it a plus plus (+/+) interaction. What does the term 'obligate mutualism' mean?
Obligate mutualism refers to a mutualistic relationship in which both organisms depend on each other for their long-term survival. Describe an example of commensalism from the lesson.
Remora fish benefit by eating scraps left by sharks, while the shark is unaffected by their presence. Which community interactions are considered types of symbiosis?
Mutualism, commensalism, and parasitism are all considered types of symbiosis. List the three main types of exploitation.
The three main types of exploitation are predation, herbivory, and parasitism. What outcomes can result from competition between species?
Competition can lead to competitive exclusion, local extinction, resource partitioning, or character displacement. Is the unaffected organism in commensalism harmed or helped?
The unaffected organism in commensalism is neither harmed nor helped; it is neutrally affected. What is a plus plus interaction in ecological terms?
A plus plus interaction is one in which both organisms benefit, as seen in mutualism. Why are mutualism and commensalism grouped as positive community interactions?
They are grouped as positive interactions because at least one organism benefits and neither is harmed. How does the red-billed oxpecker benefit from its relationship with the impala?
The red-billed oxpecker benefits by obtaining food (ticks) from the impala's fur. What is the role of the remora in its relationship with the shark?
The remora benefits by eating leftover food scraps from the shark, while the shark is unaffected. What does it mean for an organism to be neutrally affected in an interaction?
Being neutrally affected means the organism experiences neither benefit nor harm from the interaction. What is resource partitioning in the context of competition?
Resource partitioning is when competing species use different resources or niches to reduce competition. What is the fitness effect of mutualism on the organisms involved?
Mutualism increases the fitness of both organisms involved. How are mutualism and commensalism similar?
Both are types of symbiosis involving close interactions, and neither results in harm to the organisms involved.
