In reality, ecosystems are constantly evolving as they are based on dynamic processes that are constantly changing.įor instance, biocenosis are living organisms that interact with their environment and constantly transform it. Still, this doesn’t mean an ecosystem, even a healthy one, is static. For example, in grassland ecosystems, herbivores consume grass, but also feed the soil with their droppings, which allows the grass to grow back and allows some sort of balance. This means the interactions between the different organisms that make up the ecosystem contribute to a certain stability. Natural ecosystems are “balanced” systems.

What is an ecosystem? The definition of an ecosystem, how it works, how humans affect it and why – find all these issues answered below.
