The meteorite was probably 1<span>0 to 15 km (6.2 to 9.3 mi) wide</span> and affected the entire planet through a proces called "impact winter". As the name suggests, an impact winter is a period of low temperature produced by a huge cloud of ash and dust that blocks sunlight. Since sunlight is essential for plants to survive, if the sun rays are blocked by this cloud, all animals that depend on those plants (including dinosaurs) will die. The meteorite could have created such a cloud upon hitting the earth.
The term you're referring to which scientists implement to describe "different forms of life on Earth" is perhaps "Organism".
