Organism
water molecules stick to each other, creating a high surface tension in water
Cohesion
Adhesion
High specific heat
Less dense as a solid
Universal solvent
water molecules stick to other types of molecules, allowing for capillary action in plants

Explain the difference between how autotrophs and heterotrophs acquire energy.
self-nourishers
make their own food sources
nonliving sources, like the sun, or chemicals.
consume other organisms; can’t make their own
eaters of the dead
important as a means of returning nutrients back to the soil
