1. What may happen if a apex predator is taken out of a ecosystem
No changes will happen

The Preys of the predator will decline in population
How do we measure Biodiversity (not what we use)
Take count of the species and populations of the ecosystem.
Use our best guess
We Dont :\

Why are invasive species harmful to ecosystems
Are not native to the ecosystem and provide valuable resources to the organisms.
Are not native to the ecosystem so they throw off the balance of the ecosystem. Take away other organisms food sources, reduce biodiversity, and alter habitats.
They aren't
Why can lack of Biodiversity affect a ecosystem negatively.
Lack of stability in the ecosystem
