"Interaction between Biology and Environment" PPT

Part One: Situation Import

The living conditions and living space of living things are collectively called the environment. The survival of living things cannot be separated from the environment and must be affected by the environment. Can the various creatures living in the picture adapt to the environment? What impact do these organisms have on the environment during their lives? What is the relationship between living things and the environment?

learning target

1. Give examples of the effects of abiotic factors on living things.

2. Give examples of the effects of biological factors on living things.

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

The environment affects the morphology, physiology and distribution of organisms

What environments do goldfish and cacti live in? What would happen if their living environments were reversed? What does this indicate?

Answer: Goldfish live in water, and cactus lives on land. If the two are reversed, the result will be that both will die. This shows that the environment affects the survival of organisms.

Activity: Explore the effects of temperature and humidity on mold growth

Purpose requirements:

1. Observe the growth of mold under different temperature and humidity conditions;

2. Explore the effects of abiotic factors such as temperature and humidity on mold growth.

Materials and tools:

Fresh bread, petri dish, water, magnifying glass, oven or oven

PPT on the interaction between organisms and the environment, part three: exploration theme two

The impact of biological factors on organisms

1. Observe the picture below. What problem does it illustrate?

Answer: Living things are not only affected by abiotic factors, but also by biotic factors.

Discussion: Can you find examples from everyday life of organisms adapting to their environment?

2. The way organisms adapt to their environment
