The pathway of energy transfer through various stages as a result of feeding patterns of a series of organisms
- A.
Herbivore
- B.
Carnivore
- C.
Omnivore
- D.
Food chain
Correct Answer
D. Food chainExplanation
A food chain is a sequence of organisms in which each organism serves as a source of food for the next organism in the chain. It represents the pathway of energy transfer from one organism to another. In this case, the herbivore consumes plants, the carnivore consumes the herbivore, and the omnivore consumes both plants and animals. This sequential feeding pattern allows for the transfer of energy from producers (plants) to consumers (herbivores, carnivores, and omnivores) in an ecosystem. Therefore, the concept of a food chain accurately describes the pathway of energy transfer through various stages resulting from feeding patterns of a series of organisms.Rate this question:

An organism that eats only plants
- A.
Herbivore
- B.
Carnivore
- C.
Omnivore
Correct Answer
A. HerbivoreExplanation
A herbivore is an organism that eats only plants. This means that it obtains its nutrition and energy solely from consuming plant material. Unlike carnivores, which eat meat, and omnivores, which eat both plants and animals, herbivores have adapted to digest and extract nutrients from plant matter. These organisms often have specialized teeth and digestive systems that are designed to process and break down plant cellulose. Some examples of herbivores include cows, rabbits, and deer.Rate this question:

Correct Answer
C. Carrying capacityExplanation
Carrying capacity refers to the maximum population size that a particular environment can sustain over a long period of time. It represents the balance between the available resources and the needs of the population. When the population exceeds the carrying capacity, there is a strain on the resources leading to a decline in population or other negative consequences. Therefore, carrying capacity is the appropriate term to describe the largest population that an environment can support at any given time.Rate this question:

Correct Answer
C. ParasitismExplanation
Parasitism is a relationship between two species where one species, known as the parasite, benefits from the other species, called the host, while the host is harmed. This interaction is characterized by the parasite relying on the host for resources and often causing damage or disease to the host in the process. The parasite benefits from this relationship by obtaining nutrients, shelter, or other resources from the host. This type of relationship is common in nature and can be found in various organisms, such as fleas on dogs or ticks on humans.Rate this question:

- B.
Prey
- C.
Parasitism
Correct Answer
B. PreyExplanation
The term "prey" refers to an organism that is killed and eaten by another organism. In a food web, organisms are interconnected through their feeding relationships, and the prey is the organism that serves as a food source for another organism. This relationship is essential for maintaining the balance of ecosystems and the transfer of energy through different trophic levels. Prey can range from small animals to plants, and their consumption by predators helps regulate population sizes and ensures the survival of the predator species.Rate this question:

- D.
Coevolution
Correct Answer
D. CoevolutionExplanation
Coevolution refers to the evolution of two species that occurs as a result of their mutual influence on each other. This relationship often leads to mutual benefits for both species involved. In coevolution, the adaptations and changes in one species drive corresponding adaptations and changes in the other species, creating a reciprocal evolutionary process. This can include changes in behavior, morphology, or physiology. Coevolution is different from other types of relationships like commensalism, mutualism, or symbiosis, as it specifically focuses on the reciprocal evolution of two species.Rate this question:

- A.
Commensalism
- B.
Mutualsim
- C.
Symbiosis
Correct Answer
A. CommensalismExplanation
Commensalism is the correct answer because it refers to a relationship between two organisms where one organism benefits while the other is unaffected. In commensalism, the organism that benefits is called the commensal, while the organism that is unaffected is called the host. This type of relationship is characterized by the commensal obtaining resources or shelter from the host without providing any benefits or harm in return. Therefore, commensalism accurately describes the given scenario where one organism benefits and the other remains unaffected.Rate this question:
