The natural environment includes all natural resources that are necessary for life: the air, the oceans, the sun and the land Because they are vital for life, these resources must be protected from pollution and conserved Ecologists study their importance and how to use them carefully According to ecologists, resources are divided into two groups: renewable and non-renewable When a resource is used, it takes some time to replace it If the resource can be replaced quickly, it is called renewable If it can not be replaced quickly and easily, it is nonrenewable For example grass for animals is a renewable resource When cows eat the grass , the resource is used If the soil is fertilized and protected, more grass will grow Coal, however, is nonrenewable because it takes millions of years to make coal All fossil fuels are nonrenewable resources Solar energy, air and water are renewable resources because there is unlimited supply However, this definition may change, if people are not careful with these resources The amount of solar energy that reaches the earth depends on the atmosphere If the atmosphere is polluted, the solar energy that reaches the earth may be dangerous If life is going to
continue, the air must contain the correct amount of nitrogen (N), oxygen (O), Carbon dioxide (CO2), and other gases If humans continue to pollute the air, it will not contain the correct amounts of these gases
Câu 36: Ecology is the study of A human beings and animals B the environment and solar energy C human beings and their environment D natural and alternative resources
Câu 37: The natural environment consists of A the air and the oceans
(20)Câu 38: If the resource can be , it is called renewable A burnt quickly
B used easily C divided properly D replaced quickly
Câu 39: Grass for animals is a resource A clean
B nonrenewable C renewable D limited
Câu 40: According to the passage, coal is nonrenewable because it takes to make it A three billion years
B billions of years C millions of years D three million years
