Interactions and ecosystems

Sience final unit test

How do human activities affect an ecosystem?

Some humans can do bad things like litter, pollute the air or even start a forest fire. If someone littered an animal could eat it and get sick or even die. There are some good things that you could do to erase your ecological foot print. You could by recycling, riding your bike and putting out fires all the way by dumping a bucket of water on it.

What methods can we use to observe and monitor changes in ecosystems.

We can use satellites and hidden cameras to record animal behavior. We can also put trackers on animals to see where they go and where they prefer to live.
