Question

( срочно!)яким чином симетрія тіла пов'язана зі способом життя тварини?

Answer 1

Відповідь:

Формування різних видів симетрії тіла пов'язане із певним типом живлення, характером руху тварини та середовищем існування. ... Один кінець тіла стає переднім і до нього зміщаються ротовий отвір та органи чуттів, оскільки цей кінець першим зустрічає джерела подразнень. Сюди ж переміщається і центр нервової системи «мозок».

The Relationship Between Body Symmetry and Animal Lifestyles

Body symmetry refers to the arrangement of body parts in an organism. It can be classified into two main types: bilateral symmetry and radial symmetry. Bilateral symmetry is characterized by a body plan that can be divided into two equal halves along a single plane, resulting in a left and right side that are mirror images of each other. Radial symmetry, on the other hand, involves body parts arranged around a central axis, with multiple planes of symmetry.

The way body symmetry is related to an animal's lifestyle can vary depending on the specific characteristics and adaptations of the organism. Here are some key points to consider:

1. Bilateral Symmetry and Animal Lifestyles: - Bilateral symmetry is commonly found in animals that have a distinct front and back end, as well as a clear left and right side. - This type of symmetry is often associated with animals that have a more active and mobile lifestyle, as it allows for efficient movement in a specific direction. - Bilaterally symmetrical animals typically have a well-developed head region with sensory organs, such as eyes and ears, concentrated at the front end. This allows them to detect and respond to stimuli in their environment. - Examples of animals with bilateral symmetry include mammals, birds, reptiles, insects, and many other groups.

2. Radial Symmetry and Animal Lifestyles: - Radial symmetry is commonly found in animals that are sessile or have a more sedentary lifestyle, such as sea anemones, jellyfish, and starfish. - This type of symmetry allows for equal access to the environment from all sides, which is advantageous for filter-feeding or capturing prey in a 360-degree range. - Radially symmetrical animals often have body parts arranged in a circular or radial pattern around a central axis. This allows them to capture food particles or respond to stimuli from any direction. - While radial symmetry is more commonly associated with simpler organisms, some complex animals, such as sea stars, exhibit a modified form of radial symmetry.

It's important to note that while body symmetry can provide insights into an animal's lifestyle, it is not the sole determinant. Other factors, such as habitat, diet, behavior, and evolutionary history, also play significant roles in shaping an animal's way of life.
