The sun is the main source of energy because it emits vast amounts of heat and light. This energy is harnessed by plants through photosynthesis, which converts sunlight into chemical energy. This energy is then transferred through the food chain, as animals consume plants or other animals. Ultimately, all forms of energy on Earth can be traced back to the sun.

Milk is an example of a liquid because it has a definite volume but takes the shape of its container. Liquids are substances that flow freely and do not have a fixed shape, and milk fits this description. Water vapor is a gaseous form of water, paper is a solid, and an iron bar is also a solid, so they are not examples of liquids.

The average of a set of numbers is found by adding up all the numbers and then dividing by the total number of numbers. In this case, the sum of the ages is 14 + 12 + 12 + 12 + 10 + 11 + 13 = 84. There are 7 friends in the group, so the average is 84 divided by 7, which equals 12. Therefore, the correct answer is 12.

By clearing forests and cutting down trees, man can utilize the land for human activities and expansion. This destruction of trees is driven by the need for additional space to accommodate growing populations, economic development, and the demand for resources.

The statement "Gramma will be disappointed if she can't go to the concert, too" is false. The reason is not explicitly mentioned in the question, but it can be inferred that Gramma will not be disappointed if she can't go to the concert because the word "too" indicates that there is someone else who will also be disappointed. Therefore, Gramma's disappointment is dependent on whether or not the other person can go to the concert.

Soil is considered a nonliving part of an ecosystem because it is composed of minerals, organic matter, and other nonliving materials. It provides a medium for plants to grow and serves as a habitat for various organisms, but it does not possess the characteristics of a living organism. Fungus and worms, on the other hand, are living organisms and are therefore not nonliving parts of an ecosystem.

To find the grade Kim needs to get an average of 8, we need to consider the current grades and the number of tests taken. Kim has already taken 3 tests and received grades of 7, 8, and 8. To calculate the average, we add up the grades (7+8+8 = 23) and divide by the number of tests taken (3). This gives us an average of 7.67. In order to achieve an average of 8, Kim needs a total score of 32 (8 multiplied by 4 tests). Since she already has a total score of 23, she needs to score 9 on her final test to achieve an average of 8.

The population of the study refers to the group or set of individuals or objects that the study is focused on.
