Correct Answer
A. ConsumerExplanation
A consumer is a living thing that eats other living things. Consumers obtain energy by consuming other organisms, either plants or other animals. They are an essential part of the food chain and play a crucial role in transferring energy from one trophic level to another. Consumers can be herbivores, carnivores, or omnivores, depending on their diet. They are distinct from decomposers, producers, and parasites, as they directly consume other living organisms for their energy needs.Rate this question:

Correct Answer
A. DecomposerExplanation
A decomposer is a living thing that breaks down the bodies of other living things after they have died. Decomposers play a crucial role in the ecosystem by breaking down dead organisms and returning nutrients back to the soil. They break down complex organic matter into simpler forms, such as carbon dioxide and water, through the process of decomposition. Examples of decomposers include bacteria, fungi, and worms. They are essential for recycling nutrients and maintaining the balance in the ecosystem.Rate this question:

Herbivore
Correct Answer
A. HerbivoreExplanation
A herbivore is a living thing that eats only plants. Herbivores obtain their energy and nutrients by consuming plant material. They have specialized digestive systems that allow them to break down and extract nutrients from plant matter. Unlike carnivores, which eat only meat, herbivores do not consume other animals. Omnivores, on the other hand, eat both plants and animals, while consumers refer to any living thing that ingests organic matter for energy.Rate this question:

Correct Answer
A. CarnivoreExplanation
A carnivore is a living thing that eats only the bodies of other living animals. Unlike herbivores that eat plants or omnivores that eat both plants and animals, carnivores exclusively rely on consuming the flesh and bodies of other animals for their sustenance. This dietary preference makes them specialized predators in the food chain, as they have adapted physical features and hunting strategies to capture and feed on other animals. Examples of carnivores include lions, tigers, and wolves.Rate this question:

Correct Answer
A. OmnivoreExplanation
An omnivore is a living thing that eats both plants and the bodies of other animals. This means that it has a varied diet and can consume both plant matter and other animals for sustenance. Unlike herbivores, which only eat plants, and carnivores, which only eat other animals, omnivores have the ability to digest and obtain nutrients from both sources. This allows them to adapt to different environments and have a wider range of food options available to them.Rate this question:

Correct Answer
A. Population explosionExplanation
Population explosion refers to a rapid increase in the number of individuals in a particular group or population. In the context of a food chain, when one group in the chain increases very quickly, it can lead to a population explosion. This can have consequences such as competition for resources, imbalance in the ecosystem, and potential disruptions to the other organisms in the food chain. Therefore, population explosion is the most appropriate answer in this context.Rate this question:
