learning target

1. Give examples of the impact of organisms on the environment

PPT on the interaction between organisms and the environment, part 2: Exploration theme one

Bioenergy affects and changes the environment

1. Discussion: What impact do earthworms have on the environment in which they live?

Answer: It can improve the soil and increase soil fertility.

discuss:

1. Why are the psychrometers placed in different locations when measuring temperature and humidity in different locations?

Answer: Because the process of plant transpiration and water loss is completed through the leaves, the psychrometer should be placed as close to the leaves as possible in grasslands and shrubs. But bare ground does not require it.

2. Why should the average of 3 data be recorded at each measured location?

Answer: The average method after three measurements can help reduce the error.

3. Among the above-mentioned actual measurement locations, which set of data obtained serves as a comparison? Why?

Answer: Bare ground. Because what is to be studied in this experiment is the influence of vegetation on air temperature and humidity.
