k-selected species

Stable populations adapted to exist at or near the carrying capacity, K

Grow slowly and reach reproductive age late, having to devote much energy to growth and maintenance

K-selected species like a tree grows large and outcompeting  other  species

Such trees have a long-life span and produce seeds repeatedly when mature

These seeds are bigger
