Question

1.Люди на рекахстроят плотины, и бобры сторят плотиы.Объясните, чем деятельность человека отличается от действий бобра.2.Паук искусно плетет паутину-сеть , с помощью которойдобывает пищу.Человек добывает рыбу с помощью рыболовной сети.Он использует сеть в решете,в рактке для тенниса и бадминтона.Тюлевая занавеска на окне,сделанная человеком,тоже представляет собой сеть.Подумайте,чем производство сетей человеком отличается от плетения паутины пауком.

Answer 1

бобры делают это чисто для своего спасения, просто чтобы жить, человек же совершает это не для жизни, а для удобства(дешевая энергия и т п)-это другое, его плптины больше и мешают естественному ходу природы, бобровые мини платины этого не делают. к тому же сояно -шушенскаядоказала-опасно!

человеческие сети либо из вредного искуственного материала. либо просто вредны тк из дерева или растений и надо уничтожать природу, к тому же опять жепаук делает это для жизненой необходимости(он большеничем не питается), человек может есть другое, природа расчитывала на уменьшение мух джля еды но не рыбы

Answer 2

Даже не буду разлиновывать, уж, Вы меня простите)

Но оба этих случая имеют одно и тоже объяснение:

Деятельность человека носит целеполагающий характер, возможному благодаря рациональному мышлению и поставленным задачам, в отличие от действий бобров и пауков, целиком и полностью руководствующихся запрограммированными инстинктами!

Также человек использует орудия труда, недоступные животным. Ведь плотину голыми руками не построишь, как и не сошьёшь тюль, не сплётёшь сеть.

И именно в этом есть различие между плетением паутины пауком и производством сетей человеком

Difference between human activities and beaver actions in building dams:

The activities of humans and beavers in building dams differ in several ways. Here are some key differences:

1. Purpose: Humans build dams primarily for water management, hydroelectric power generation, irrigation, and flood control. Dams constructed by humans are often large-scale infrastructure projects designed to meet specific human needs [[1]]. On the other hand, beavers build dams primarily to create suitable habitats for themselves and their offspring. Beaver dams help them regulate water levels, create ponds, and provide protection from predators [[2]].

2. Construction methods: Humans use heavy machinery, engineering techniques, and construction materials to build dams. They often involve concrete, steel, and other man-made materials to create structures that can withstand high water pressure and serve their intended purposes [[3]]. In contrast, beavers construct dams using natural materials such as branches, logs, mud, and stones. They use their teeth and paws to cut down trees and arrange the materials to create a dam [[4]].

3. Scale: Human-built dams can be massive structures that span across rivers or valleys, sometimes reaching heights of hundreds of feet and creating large reservoirs. These dams can have a significant impact on the surrounding environment and ecosystems [[5]]. Beaver dams, on the other hand, are generally smaller in scale and are built in streams or small rivers. They create localized changes in water flow and create smaller ponds or wetlands [[6]].

4. Intentionality: Human dam construction is a deliberate and planned activity, involving engineering studies, environmental impact assessments, and legal permits. It is a conscious decision made by humans to alter the natural environment for specific purposes [[7]]. Beaver dam construction, on the other hand, is an instinctive behavior driven by the beavers' natural instincts and needs. They do not have a conscious understanding of the ecological consequences of their actions [[8]].

5. Longevity: Human-built dams are designed to be long-lasting structures, often with a lifespan of several decades or even centuries. They require regular maintenance and monitoring to ensure their structural integrity and functionality [[9]]. Beaver dams, on the other hand, are usually temporary structures. Beavers continuously maintain and modify their dams as needed, but they do not aim for long-term durability [[10]].

Difference between human production of nets and spider web weaving:

The production of nets by humans and the weaving of spider webs by spiders differ in several ways. Here are some key differences:

1. Purpose: Humans produce nets for various purposes, including fishing, sports (e.g., tennis, badminton), safety (e.g., safety nets), and decorative purposes (e.g., curtains). The purpose of human-produced nets is primarily functional, serving specific human needs [[11]]. On the other hand, spiders weave webs primarily for capturing prey. Spider webs are intricate structures designed to trap insects and other small creatures for the spider's food source [[12]].

2. Construction methods: Humans produce nets using various materials, such as nylon, cotton, or synthetic fibers. They use tools and machines to create specific patterns and shapes, depending on the intended use of the net [[13]]. Spiders, on the other hand, produce webs by secreting silk from specialized glands in their bodies. They use their legs and spinnerets to manipulate the silk and create intricate web structures [[14]].

3. Complexity: Human-produced nets can vary in complexity depending on their purpose. Some nets, like fishing nets, can be relatively simple in design, while others, like sports nets or safety nets, may have specific patterns and structures to meet safety or functional requirements [[15]]. Spider webs, on the other hand, are incredibly intricate and complex structures. They often consist of multiple layers, radial lines, sticky capture threads, and support lines, all carefully woven together [[16]].

4. Adaptability: Humans can adapt the design and construction of nets to suit specific needs. They can modify the size, shape, and material of the net to optimize its functionality for different purposes [[17]]. Spiders, on the other hand, have a limited ability to adapt their web design. They generally follow instinctive patterns and adjust their web-weaving behavior based on environmental factors like wind direction and prey availability [[18]].

5. Intentionality: Human production of nets is a conscious and intentional activity. Humans design and create nets with a specific purpose in mind, using their knowledge and skills to achieve the desired outcome [[19]]. Spider web weaving, on the other hand, is an instinctive behavior for spiders. They follow innate patterns and behaviors passed down through generations, without conscious decision-making or planning [[20]].

In summary, the activities of humans and beavers in building dams, as well as the production of nets by humans and the weaving of spider webs by spiders, differ in terms of purpose, construction methods, scale, intentionality, and adaptability. Humans' actions are driven by conscious decision-making and specific human needs, while beavers and spiders follow instinctive behaviors to meet their own requirements.
