Types Of Worms: Trivia Facts Quiz

Explanation
Segmented worms are also known as Annelida. This is because the phylum Annelida includes organisms such as earthworms, leeches, and bristle worms that have a segmented body plan. The word "annelida" is derived from the Latin word "annellus," meaning "little ring," which refers to the segmented nature of these worms.

Explanation
Segmented worms are bilaterally symmetrical because their bodies can be divided into two equal halves along a single plane, resulting in a mirror image. This symmetry allows for efficient movement and coordination of body parts. Unilaterally symmetrical organisms have only one plane of symmetry, while multilaterally symmetrical organisms have multiple planes of symmetry. None of the above options accurately describe the symmetrical nature of segmented worms.

Explanation
Tealworm is not a type of worm. While tapeworm, flatworm, and fluke are all well-known types of worms, tealworm is not a recognized term in the field of biology. This suggests that tealworm is either a made-up term or a less commonly known term for a specific type of worm. However, without further information, it is difficult to determine the exact nature or characteristics of tealworm.

Explanation
Worms eat at night because they are nocturnal creatures. They prefer to come out of their burrows and feed on decaying organic matter during the darkness. This behavior helps them avoid predators and extreme temperatures during the day. Additionally, worms have a sensitive sense of touch and light, making them more active and efficient in their feeding activities during the nighttime.

Explanation
Worms are believed to have been around 600 million years ago. This is based on scientific evidence and research that suggests the existence of early worm-like organisms during this time period. Fossil records and genetic studies have provided insights into the evolutionary history of worms, indicating their presence in the Earth's history dating back to 600 million years ago.

Explanation
This statement is true. Earthworms are known for their ability to consume a large amount of organic matter relative to their body weight. They play a vital role in decomposition and nutrient cycling in ecosystems. Earthworms have a high metabolic rate and efficient digestion system, allowing them to process and break down organic material quickly. They ingest soil and organic matter, extracting nutrients and excreting nutrient-rich castings. Their feeding habits make them important contributors to soil fertility.

Explanation
The statement "Worms are cold-blooded creatures" is true. Cold-blooded creatures, also known as ectothermic animals, rely on external sources to regulate their body temperature. Worms fall into this category as they do not have the ability to internally regulate their body temperature. Instead, they adapt to the temperature of their environment. This is why worms are commonly found in soil or other moist areas, as these environments provide the necessary conditions for their survival.

Explanation
Worms get rid of dead cells with their kidneys. Kidneys are organs responsible for filtering waste products from the blood and excreting them as urine. In worms, the kidneys, also known as nephridia, perform this function by filtering waste materials and excess fluids from the body. Therefore, the correct answer is "Kidney."

Explanation
This statement is true. Earthworms do not have ears or eyes. They rely on other sensory organs to navigate through their environment. They have specialized receptors on their skin that can detect vibrations and changes in light intensity. These sensory organs help them detect predators, find food, and navigate their surroundings.

Explanation
Worms have the ability to regenerate their tails, making the statement "Worms can regenerate their tail" true. This means that if a worm's tail is damaged or severed, it has the capability to grow a new tail in its place. This regenerative ability is a unique characteristic of worms and allows them to recover from tail injuries.
