Our world is a very big place! In fact, it is so big that there are many different kinds of ecosystems for our plants and animals to live in! An ecosystem is a place where living and non-living things interact in order for the living things to survive. Within an ecosystem, there are communities of living organisms that live in their natural habitats (homes). Within a community, there are several populations, or types, of animal.
This is a wetland ecosystem
This wetland ecosystem is a great example of what we have been talking about! First of all, there are living and non-living things in this wetland ecosystem. Can you think of all of them? Work with a partner to figure out the living and non-living parts of this ecosystem.
Remember all that talk about communities and populations? Well, they exist in this wetland too! This wetland is a habitat (home) to many different species of plant and animal. All of the plants and animals that live in this habitat for the community in this wetland. However, there is not just one type of plant or animal that lives here. There are SEVERAL different types. Each different kind of animal that lives here makes up a population. For example, ALL of the snakes that live here make up the snake population. And all of the fish that live here make up the fish population. A community has several different populations living within.
So, then, how do the living and non-living parts of the ecosystem interact? What are the different categories?
Now we will go and do some practice! You will have several cards that have written scenarios on them. Your job will be to work with a partner to place the cards into the correct interactions category. Once you have them placed, let me know and I will come and look at them. Be ready to defend any choice you make with complete sentences!
