China's culture is profound and has a long history. Many poems, lines and sayings contain a wealth of biological knowledge, so please try to answer and explain the relevant poems from a biological point of view. Answers are as follows:

Analysis: 1, movement is the main feature of animals, a variety of animals have different organs of locomotion, movement is different. Animals move in many different ways, such as flying, swimming, crawling, running and so on.

2, human and mammalian locomotor system including bone, joints and skeletal muscle three parts of the composition, bone plays a supportive role, the bone joints play a protective role, bone, joints and skeletal muscle under the domination of the nervous system and the coordination of other systems **** with the completion of the.

3, the composition of the bone, including organic and inorganic material, the more organic material, the more flexible the bone, the more inorganic material, the greater the hardness of the bone.

4, the breeding behavior of birds include: courtship, mating, nesting, egg-laying, incubation, brooding several stages. The poem "The Swallow pecks at the mud in spring" describes the nesting behavior of swallows in their breeding behavior.

5. An ecosystem consists of living and non-living parts. The biotic part includes producers, consumers and decomposers, and the abiotic part includes sunlight, air and water.

Solution? Solution: 1, "the sea is wide by the fish, leaping sky high let the birds fly" in the description of the fish live in the water, with gills to breathe, with fins to swim, the movement is swimming. Birds live in the air. Birds, the body is streamlined, the body surface is covered with feathers, the forelimbs into the wing, the wing is the flight organ, the movement is flying.

2, muscle tissue is mainly composed of muscle cells, with contraction, diastole. Such as cardiac muscle, smooth muscle and so on. So the "bone" in the "bone" belongs to the connective tissue, "meat" belongs to the "muscle tissue", respectively. Muscle is attached to bone and the two are connected.

3, the composition of the bone, including organic and inorganic material, the more organic material, the more flexible the bone, the more inorganic material, the greater the hardness of the bone. Older people's bone organic matter is less than 1313, inorganic matter more than 2/3, so the elderly bone elasticity is small, hard and brittle, easy to fracture. So the elderly fall easy to fracture because of the bone inorganic content of more than 2323.

4, in the reproductive season, animals have their own way of reproduction, the reproduction of birds reproductive behavior: the behavior related to animal reproduction. Such as occupying the nest, courtship, mating, incubating eggs, feeding and a series of other behaviors, "who new swallows pecking the mud of spring" reflects the reproductive behavior of swallows.

5, the falling red is a ruthless thing, into the spring mud more protective flowers. The reason is: the plant contains organic matter in the flowers, after falling to the ground, the decomposer is broken down into carbon dioxide and water and other inorganic substances, and then by the photosynthesis of the plant body in order to manufacture organic matter.

The answer is:

1. Birds live in the air; their mode of locomotion: flying; fish live in the water; their mode of locomotion: swimming.

2. Yes; In the locomotor system, muscles are attached to bones .

3, Grandpa; because older people have more than 2/3 inorganic material and less than 1/3 organic material in their bones, the bones are brittle and hard and easy to fracture .

4, breeding behavior.

5. Petals are broken down by decaying microorganisms in the soil into simple inorganic matter that is reused by the plant.
