An Ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscapes, work together to form a bubble of life 🌍. It is very hard to determine the boundaries of such a system. Since ideally you would place a boundary around a perfect bubble where everything inside the bubble interacts and the things outside of this bubble do not have a very big effect. This forest can be regarded as an imperfect bubble, with the trees in it interacting with the animals living in the forest and creating a forest microclimate. The pastures outside of the forest are then another ecosystem with a different microclimate and plant species composition. Of course the forest experiences a lot of influence from its surroundings and it does influence its surroundings as well, but for now, let’s consider it an ecosystem.
