Correct Answer
G. MutualismExplanation
Mutualism is the correct term for the relationship described in the question. Mutualism is a type of symbiotic relationship where both species involved benefit from each other's presence. In this case, the oxpecker bird benefits by feeding on ticks, while the buffalo benefits from having the ticks removed. This relationship is mutually beneficial for both species, hence it is called mutualism.Rate this question:

Correct Answer
J. Parasite/parasitismExplanation
The relationship described in the passage matches the concept of parasitism, where one organism (the tick) benefits at the expense of another organism (the person) by living in or on the host organism and causing harm. The tick attaches itself to the person and transfers bacteria that causes illness, which is characteristic of a parasitic relationship.Rate this question:

Correct Answer
I. CommensalismExplanation
Commensalism is a type of relationship between two species where one species benefits while the other is neither harmed nor helped. In commensalism, one species takes advantage of the resources or activities of the other species without causing any harm. This relationship is often seen in nature where one species uses another species for transportation, protection, or access to food, without providing any benefits in return. An example of commensalism is a bird building its nest in a tree, using the tree for support and shelter without affecting the tree in any way.Rate this question:

Correct Answer
J. Parasite/parasitismExplanation
Parasite/parasitism refers to a relationship in which one organism (the parasite) lives in or on another organism (the host) and causes harm to the host. The parasite benefits from this relationship by obtaining nutrients or resources from the host, while the host is negatively affected. This type of relationship is common in nature and can have significant impacts on the health and survival of the host organism.Rate this question:

Correct Answer
L. CompetitionExplanation
Competition refers to the struggle between organisms for limited resources such as food, water, and space. When two species inhabit the same niche and compete for the same resources, there is intense competition between them. This competition can lead to one of the species outcompeting the other and eventually causing the extinction of the weaker species.Rate this question:

Correct Answer
D. AdaptationsExplanation
Adaptations refer to the traits or characteristics that organisms develop over time to help them survive and reproduce in their environment. These adaptations can be physical, behavioral, or physiological and are passed on to future generations through inheritance. Through the process of natural selection, individuals with beneficial adaptations are more likely to survive and pass on their genes, while those with less advantageous traits are less likely to reproduce. Therefore, adaptations play a crucial role in the survival and evolution of species over time.Rate this question:

Correct Answer
A. Natural selectionExplanation
Natural selection is the process by which certain traits or characteristics become more common in a population over time because they provide a survival or reproductive advantage. Individuals with these advantageous traits are better suited to their environment and are more likely to survive and reproduce, passing on their traits to future generations. This process leads to the adaptation of species to their specific environments, as those individuals with traits that are less suited to the environment are less likely to survive and reproduce.Rate this question:

J. HostExplanation
A host is an organism that is harmed by another organism, which lives in or on it. This relationship is known as parasitism, where the parasite benefits at the expense of the host. The parasite relies on the host for survival and reproduction, while the host is negatively affected by the presence of the parasite. This interaction is a form of symbiosis, where two organisms live in close association with each other. The host provides a suitable environment for the parasite to thrive, while the parasite causes harm to the host.Rate this question:

A. NicheExplanation
The term "niche" refers to the role or position that an organism occupies within its habitat. It includes the specific resources it uses, how it interacts with other organisms, and its adaptations to the environment. Understanding an organism's niche helps to understand its ecological relationships, such as competition, predation, or symbiosis, and how it contributes to the overall functioning of the ecosystem.Rate this question:

E. PredationExplanation
Predation refers to the act of one organism killing another organism for food energy. It is a natural process in which the predator hunts and feeds on the prey. This relationship is essential for maintaining the balance of ecosystems as it controls population sizes and helps in the survival of the fittest. Predation plays a crucial role in the food chain and is a fundamental aspect of the natural world.Rate this question:

Which of these relationships is the best example of parasitism?
- A.
A bat pollinating a saguaro cactus
- B.
An oyster crab living off the algae on it's host oyster
- C.
A flea living on cat blood
- D.
Ants protecting a tree that produce its only food
Correct Answer
C. A flea living on cat bloodExplanation
A flea living on cat blood is the best example of parasitism. In this relationship, the flea benefits by feeding on the cat's blood, while the cat is harmed by the flea's presence and the potential for disease transmission. The flea benefits at the expense of the cat, making it a clear example of parasitism.Rate this question:

Why are there fewer organisms at the top of the food chain?
- A.
There are usually few organisms at the top because there is a limited amount of energy available at that level of a food web.
- B.
There are usually few organisms at the top because the organisms at the top of the food chain care for their young longer than organisms lower on the food chain.
- C.
There are usually few organisms at the top because the organisms at the top of the food chain consume are omnivores that consume diverse kinds of organisms that are lower on the food chain.
- D.
There are usually few organisms at the top because the organisms at the top of the food chain are scavengers consuming what other organisms have left behind.
Correct Answer
A. There are usually few organisms at the top because there is a limited amount of energy available at that level of a food web.Explanation
The correct answer is that there is a limited amount of energy available at the top of the food chain. This is because energy is transferred from one organism to another as it moves up the food chain, and there is a loss of energy at each trophic level. As a result, by the time the energy reaches the top of the food chain, there is only a small amount left to support a limited number of organisms.Rate this question:
