Answer
### Answer:
**Question 32**
Mean: 71
Median: 68
Mode: None
Range: 61
**Question 33**
An energy - pyramid is a graphical representation of the flow of energy through different trophic levels in an ecosystem. It has a broad base representing the producers (usually plants) which have the most energy. As you move up the pyramid to primary consumers (herbivores), secondary consumers (carnivores that eat herbivores), and so on, the amount of available energy decreases. The pyramid is widest at the bottom and narrows at the top.
**Question 34**
Disruptions or changes in a food - web can be caused by factors such as habitat loss, introduction of invasive species, over - hunting or over - fishing, pollution, climate change, and disease.
**Question 35**
The process of photosynthesis is the conversion of light energy into chemical energy by plants, algae, and some bacteria. The equation for photosynthesis is: $6CO_2 + 6H_2O+light\ energy\rightarrow C_6H_{12}O_6 + 6O_2$. In this process, carbon dioxide and water are taken in by the plant. Light energy is absorbed by chlorophyll in the chloroplasts. This energy is used to convert the carbon dioxide and water into glucose (a sugar) and oxygen. The oxygen is released into the atmosphere, and the glucose is used by the plant for energy and growth.
**Question 36**
The Sun provides the majority of energy for all of Earth's systems. It powers the water cycle, drives weather patterns, and is the primary source of energy for photosynthesis, which in turn supports most of the life on Earth.
### Explanation:
**Question 32**
## Step1: Calculate the mean
The sum of the numbers is $106 + 45+54 + 82+68=355$. There are 5 numbers. The mean is $\frac{355}{5}=71$.
## Step2: Find the median
Arrange the numbers in ascending order: $45,54,68,82,106$. The middle number is 68, so the median is 68.
## Step3: Determine the mode
No number repeats, so there is no mode.
## Step4: Calculate the range
The range is the difference between the largest and smallest numbers. $106 - 45=61$.
**Question 33 - 36**: These are knowledge - based questions in the field of natural science (biology and environmental science). The explanations are based on well - known scientific concepts and principles.
