artificial ecosystems are not invaded by humans
they are being affetced mostly by humans and pollution.
deforestation, hunting, recreational activities (leading to littering)
explain in short answer interactions between humans and natural ecosystems.
A natural ecosystem is one that occurs without any outside influences. Humans are the main inhibitors of most natural ecosystems.
NO natural disasters can help an ecosystems
We don't spend a lot of time in natural ecosystems because where ever we are, chances are the biotic and abiotic factors has been changed. They change becuase humans changed it. When humans change the ecosystem it is no longer a natural ecosystem. We use natural ecosystems and turn it into thing's like golf courses, housing area's etc. So basically we are in non natural ecosystems most of the time. But the only time we do use (or are in) a natural ecosystem in when we are in/by a forest, pond (that was naturally made) etc. Hope that helped :)
The nonliving resources that humans obtain from ecosystems are called
Humans and natural activities affect the earth. The environment is also affected.
What about it?
how are symbiotic relationships affected
The role of humans in ecosystems is that they have to depend on their ecosystems to provide food for survival and to recycle wast. They also have a role to destroy their environment by polluting the air, land, and water.
Yes some do involve humans
Humans are the largest polluters in ecosystems.
engineered ecosystems have uniform abiotic featues and low biodiversity while a natural ecosystem is quite the opposite as it has a high biodiversity (many different biotic species) and naturel abiotic factors in simpler words natural ecosystems have no human activity associated with the ecosystem. while engineered ecosystems are ecosystems with human activity involved with them (Ex. pesticides).
Protecting natural habitat is important because plants, animals, and people need natural resources for survival. Humans rely on the earth's ecosystems for basic needs such as food, water, and air.
What can cause ecosystems to change including natural disasters
Marine biologists helps us to understand the natural variability in marine ecosystems and to detect whether changes that occur are natural or induced by the actions of humans.
C. Treated sewage is less damaging to the environment than untreated sewage
Animals have had their habitats destroyed, many species have had to relocate into other environments, causing natural shifts in the ecosystems that were previously existing.
Industrial development has affected ecosystems very negatively. It is a cause of pollution and deforestation along with litter. This all can kill organisms.
