When my summer holidays came I was very happy! The weather was fine so my friends and I went for a walk every day. It was fun! Then I spent a month in the country where my grandfather and grandmother lived. It was great. I drank milk and ate a lot of tasty food which my granny prepared for me. I have many friends in this village because I go there every holidays. We played football and tennis every day! There is a small river near the forest and we swam when the weather was fine. It was great! I liked my holidays very much.
Когда наступили летние каникулы, я был очень счастлив! Погода была хорошая, так что мои друзья и я ходили гулять каждый день. Это было весело! Затем я провел месяц в деревне, где живут мои дедушка и бабушка . Это было здорово. Я пил молоко и ел много вкусной пищи, которую моя бабушка готовила для меня. У меня много друзей в этой деревне, потому что я езжу туда каждые каникулы. Мы даже играли в футбол и теннис! Около леса есть небольшая речка. Мы купались, когда погода была хорошая. Это было здорово! Мне очень понравились мои каникулы.
A. The ecosystem includes a complex of living (biotic) and non-living (abiotic) elements, habitat and their interaction with each other to create a continuous cycle of substances and energy
B. Nature needs protection, because man pollutes and destroys it and can cause irreparable harm to it. As an example, waterlogging and salinization of soils, pollution with oil products, radioactive waste and landfills.
C. 1.Physical pollution includes thermal (thermal), light, noise, vibration, electromagnetic, and ionizing pollution.
2.Light pollution is a violation of the natural illumination of the environment. Leads to disruption of the rhythms of activity of living organisms. Increasing water turbidity in water bodies reduces the flow of sunlight to the depth and photosynthesis of aquatic vegetation.
3.Noise pollution. Sound – as a physical phenomenon, is a wave motion of an elastic medium. Noise – any kind of sounds that interfere with the perception of useful sounds or break the silence. The sound frequency range that the human ear perceives is from 16 to 20,000 Hz. Sound waves with a frequency below 20 Hz are called infrasonic, and above 20,000 – ultrasonic.
D. 1.An ecosystem or ecological system is a biological system (biogeocenosis) consisting of a community of living organisms (biocenosis), their habitat (biotope), and a system of connections that exchange substances and energy between them. One of the main concepts of ecology. An example of an ecosystem is a pond with plants, fish, invertebrates, microorganisms that make up the living component of the system, and a biocenosis. The pond as an ecosystem is characterized by bottom sediments of a certain composition...2.Changes made in one component of the ecosystem can lead to adverse consequences in the functioning of the entire ecosystem. Intelligent human activity is not always able to foresee the consequences of its activities.
F. Violation of the ecological balance between natural factors and human activity is a socio-ecological crisis. This means that the balance between the environment and society is broken. This situation can lead to the death of humanity
