false?
Biology

Gemiola [76]4 years ago

Answer:

TRUE

Explanation:

No biological system is completely closed.

A nutrient cycle is the movement and exchange of both organic and inorganic matter back into the production of matter. This cycle is a recycling system which always occurs no matter what.

In a system that looks closed (closed loop), nutrients may be limited because they are not cycled through  the system fast enough and/or it is not possible to compensate for deficiencies by  migration.

natulia [17]

Believe it or not, 99.9% of the species on Earth have gone extinct. Now, not all of these were caused by Humans, some were caused by MAJOR cataclysmic events such as the extinction of dinosaurs or other prehistoric animals that make up a large amount of the species on Earth. And remember that all the prehistoric plants are also included, because every plant organism is ALSO a species.
