Alright bilgate — let's do this.
Here are the solutions for the questions from the image:
12. The process by which water moves downward and vertically into the soil is:
- Infiltration is the process by which water on the ground surface enters the soil. It is the initial downward movement of water into the soil.
The correct option is A. Infiltration.
13. Places with the same amount of rainfall are joined by lines called:
- Isohyets are lines on a map connecting points that receive equal amounts of rainfall over a given period.
The correct option is C. Isohyets.
14. The Climograph in Fig 2 is for?
- The climograph shows consistently high rainfall throughout the year (total 2920 mm) and a very small annual temperature range (3-2°C), indicating consistently high temperatures. These characteristics are typical of an Equatorial climate, which experiences hot and wet conditions year-round.
The correct option is D. Equatorial.
15. Instructions for questions 14 – 15 Read the two statements. Determine if they are true or false. Then select as follows: A. If both statements are true B. If the 1st is true and the 2nd is false C. If both statements are false D. If the 1st statement is false and the 2nd is true
- The statements for question 15 are not visible in the provided image. Therefore, this question cannot be answered.
16. First statement: Moving air hits the vane, forcing the instrument's arrow to point a direction. Second statement: The instrument mentioned is the wind vane.
- The first statement accurately describes how a wind vane works: moving air (wind) pushes against the vane, causing it to align with the wind direction, and an arrow indicates that direction.
- The second statement correctly identifies the instrument described as a wind vane.
- Since both statements are true.
The correct option is A. If both statements are true.
17. Climate is different from weather in that:
- Climate refers to the long-term average of weather conditions in a region, typically studied over periods of 30 years or more. Weather refers to the atmospheric conditions at a specific time and place.
The correct option is C. The average weather condition is studied for a long time.
18. Trees of tropical Rain forest and coniferous forest are similar in that:
- Tropical rainforests are characterized by evergreen trees that do not shed their leaves seasonally. Coniferous forests (e.g., pine, spruce, fir) are also predominantly composed of evergreen trees that retain their needles year-round.
The correct option is C. They are evergreen.
19. The most numerous members of a Trophic level in a food chain are:
- Producers (like plants and algae) form the base of almost all food chains. They convert energy (usually from the sun) into organic matter, and their biomass and numbers are typically the largest in an ecosystem to support all higher trophic levels.
The correct option is B. Producers.
20. The role of Decomposers in a food chain is to
- Decomposers (such as bacteria and fungi) break down dead organic matter (dead plants, animals, and waste products). This process recycles nutrients back into the soil, making them available for producers.
The correct option is B. Break down dead organisms.
