3rd Evs Mark 20

Sparrows build nests.

Sparrows primarily eat insects and grains. They have a diverse diet that includes small insects like beetles, caterpillars, and spiders, as well as seeds, grains, and fruits. This combination of food sources provides sparrows with the necessary nutrients for their survival. While sparrows may occasionally scavenge for flesh or use twigs for nesting materials, these are not their main sources of food.

Living things get food from their environment. This includes plants that obtain food through photosynthesis, animals that consume plants or other animals, and microorganisms that break down organic matter. The environment provides a variety of food sources such as sunlight, water, and nutrients that are essential for the survival and growth of living organisms.

Vultures and foxes are known to eat the flesh of dead animals. Vultures are scavengers that primarily feed on carrion, including the carcasses of dead animals. They have a keen sense of smell and can locate carcasses from great distances. Foxes, on the other hand, are opportunistic predators and scavengers. They are known to scavenge on dead animals when the opportunity arises, but they also hunt and kill their own prey. Both vultures and foxes play an important role in the ecosystem by helping to clean up and recycle nutrients from dead animals.

Sparrows grow by eating insects and food grains. This statement is true because sparrows are omnivorous birds that feed on a variety of foods, including insects and grains. Insects provide them with protein and other essential nutrients necessary for their growth and development. At the same time, food grains such as seeds and grains are also a significant part of their diet, providing them with carbohydrates and energy. Therefore, sparrows rely on both insects and food grains to support their growth.

Plants are living organisms that belong to the kingdom Plantae. They are capable of photosynthesis, growth, reproduction, and responding to their environment. Unlike non-living things, plants have cells, tissues, and organs that enable them to carry out various life processes. They require water, nutrients, and sunlight to survive and play a vital role in the ecosystem. Therefore, the statement that plants are non-living things is incorrect.

A railway engine is not a living thing as it is a mechanical device used to pull or push trains on railway tracks. Living things are organisms that have the ability to grow, reproduce, respond to stimuli, and maintain homeostasis, which a railway engine does not possess.

Sparrows are known to be attentive and caring parents, often taking great care of their young ones. They build nests, provide food, and protect their offspring from predators. This behavior is commonly observed in sparrows, making the statement "Sparrows take a lot of care of their young ones" true.

The correct answer is "cloth" because the sentence is talking about weaving, which is the process of creating fabric or cloth. The materials mentioned, cotton, wool, and silk, are all commonly used to make cloth.

The question asks what is made from clay, stone, and wood by man. The only option that fits this description is a house. Houses are commonly constructed using materials such as clay bricks, stone, and wood for various components like walls, roofs, and floors. Therefore, a house is the correct answer.

The correct answer is "fall off." In the given sentence, it is mentioned that leaves "rot and get mixed with the soil." This implies that the leaves are no longer attached to the trees, indicating that they have fallen off. Therefore, "fall off" is the appropriate term to complete the sentence.

Sparrow's nests typically contain eggs. This is because sparrows build nests to lay and incubate their eggs. Eggs are an essential part of a sparrow's reproductive cycle, as they are necessary for the continuation of their species. Therefore, it is reasonable to expect that a sparrow's nest would contain eggs rather than grains or rocks, which do not serve the same purpose.

The statement is true because some plants have adapted to disperse their seeds through wind. These plants produce lightweight seeds or fruits with structures like wings or parachutes that enable them to be carried by the wind to new locations for germination and growth. This method of seed dispersal increases the chances of plants colonizing new areas and reduces competition for resources with parent plants. Examples of plants that disperse seeds by wind include dandelions, maples, and cottonwood trees.

Wool and silk are both natural fibers that are obtained from animals. Wool is derived from the fleece of sheep, while silk is produced by silkworms. Trees, on the other hand, do not produce these fibers. Therefore, the correct answer is animals.

The correct answer is "barren." The word "barren" suggests that the lands in the environment are unable to support the growth of plants or crops. This implies that the lands are infertile, lacking in nutrients, and unable to provide nourishment for vegetation. The term "barren" indicates a desolate and unproductive condition, highlighting the absence of life and vegetation in the environment.

The word "seeds" should be struck out because sheep do not typically eat seeds. They primarily eat leaves and grass.

The statement is incorrect. Sheep do not give us cotton. Sheep produce wool, not cotton. Cotton comes from the cotton plant.

Barren lands are characterized by a lack of vegetation and plant life. The absence of bushes on barren lands is a key feature that distinguishes them from other types of landscapes.

Sparrows lay their eggs and raise their young ones in nests. The question is asking for the correct term that refers to the young ones, and the answer is "young ones."

Rocks cannot grow as they are inanimate objects and do not possess the ability to undergo growth. Growth is a characteristic of living organisms, such as plants or animals, which can increase in size or develop new parts over time. Therefore, the statement that rocks can grow is incorrect.
