Which statement about abiotic changes to an ecosystem is true ?
Lena [83]
The very first one is the answer-

Abiotic changes have the ability to dictate biotic ones. This can be caused by humans.
For example: an abiotic thing can be an element like water. If the water in a lake gets poisoned by chemical compounds, this is an abiotic change. However, since the lake is now poisoned it’ll likely harm or even kill fish, bacteria, algae, and any other wildlife living within the lake. It doesn’t stop there though, without the lake surrounding animals won’t have clean water to drink, they can now die from either the poisoning, dehydration, or starvation if they lived off of the aquatic life from the lake.
