On the 26th of October, the class of Science 9 went on a walk to discover how the different spheres interact with one another. We took pictures and analyzed the ways of interacting between different sources. These are the pictures I took and an explanation of each one.
In this picture, we can see that the geosphere is interacting with the biosphere because moss is growing in between the pavement. It is also an interaction between something abiotic and biotic.
Here, something abiotic is interacting with something biotic which is an interesting example, but also something that is horrible for the environment (in the case of this picture) since this is litter.
This picture represents the atmosphere reacting with the biosphere through the process of photosynthesis. The sunlight gives to the trees and then the trees produce oxygen (with the help of other things as well)
This is another representation of the biosphere and geosphere reacting. The soil has rocks and there is many plants growing from the soil as well as the roots are buried into the soil.
It’s difficult to see here, but here is an example of the biosphere and hydrosphere reacting. Plants are sort of growing near the/on the water. It is also a good example of an reciprocal relationship since the water helps the plants grow and the plants give back oxygen to the water.
In this picture there is also an example of the hydrosphere and biosphere reacting, but in a different way. It’s rain water on top of grass.
In this ecosystem, what is a natural event that could affect one or more other spheres? Explain
A natural event that occurs that affects more spheres is simply rain. This is because when it rains, it comes from the atmospheres since that’s where the clouds are. The rain is part of the hydrosphere and it falls onto the geosphere where is where some of the biospheres roots are (if we’re talking about plants) and then the plants get water.
