Army ant swarms generally avoid fighting each other because a clash between two lethal social armies would likely cause mutual annihilation, so natural selection favors passing, retreating, or other avoidance behaviors to prevent catastrophic losses.

Hydrostatic pressure increases with the weight of the water column, so at hadal depths (around 6,000 meters and below) pressures reach roughly 1,100 times surface pressure, producing crushing forces that would destroy unprotected objects or organisms.

A general drive to explore and manipulate novel objects pushes corvids to test human artifacts, and associative learning quickly links each item's specific reward or harm, shaping future interactions.

Nitrogen from decaying salmon carcasses enters forest soils and is absorbed by mycorrhizal networks, which then redistribute that marine-derived nitrogen through tree-to-tree connections, linking ocean productivity to forest growth and health.

Ocean currents shape large-scale weather and climate because they carry warm water and the heat it contains from the equator toward the poles, redistributing solar energy and altering atmospheric temperature patterns.

Mother trees preferentially allocate more carbon to genetically related seedlings because they can direct resources through fungal links to kin, especially after injury, effectively passing support and fitness benefits down their genetic lineage.

If you shaved off all land and dumped that volume into the ocean basins, the added material would fill low regions and produce a global ocean roughly two miles deep, illustrating how land volume compares to basin capacity.

Ecosystem resilience emerges from many species interactions because those interactions create feedbacks and cycles (like nutrient cycling and predation) that sustain function; removing key parts can break feedbacks and flip the system into degraded, hard-to-reverse stable states.
