An ecosystem that is not sustainable can break down when a natural disaster occurs. this can lead to organisms in the ecosystem either leaving the area or dying off. increased biodiversity results in a more sustainable ecosystem because — a) a greater number of plant species means that there is less barren land b) a greater variety of species present allows more organisms to adapt after changes occur c) the transition area between two ecosystems is narrower d) there are fewer species to be affected by environmental stresses

When organism adapt there is a greater chance or survival.

The answer is: B

to increase speed you need to decrease frictiona dn drag hense why sprinters wear tight track suits to keep tight against there skin to keep away from wind and decrease the amount of drag you are carrying.a swimmer will wear the tightest swim suit they can possibly fit into (i was a size 28 swim suit at meets i wore a   size 23) why? because the tighter your clothing is the less drag and negative force you have. the heavier the clothe the slower and more wind gets caught. cotton tends to hold onto alot of sweat and water making it slower then say a track suit (no idea what they are made of but they are really comfy around your answer )

hpv is the answer
