Last one - Biodiversity is the diversity of species in an area, which makes an ecosystem better prepared for major changes
Explanation:
If one crop struggles to grow then there will be plenty of others to substitute it. If a prey animal is dying at a faster rate and harder to find, predators can have other prey options and so forth. Biodiversity makes it so ecosystems can get past change.
A is your answer I believe because they do indeed provide a way to review other scientists work and or experiments
1. <span>D. Molten material beneath Earth's crust rises to the surface.
2. </span><span>A. The mid-ocean ridges
(This is asking for what form. The Andes is a mountain range in Peru)
3. </span><span>C. Subduction causes the ocean floor to sink into deep ocean trenches.
(Subduction is when part of the ocean floor sinks under a deep-ocean trench and return the the mantle; this is caused by the movement of tectonic plates)
