Answer;
The above statement is false.
Explanation;
The correct statement would have been;
The half life of an element of an element is the amount of time is it takes for half of radioactive isotope to decay.
-Isotopes are atoms of the same element that have the same atomic number but different mass number. Radioactive decay happens when an unstable atomic nucleus of an isotope spontaneously changes to a lower-energy state and spits out a bit of radiation.
-Half life is defined as the time it takes for one-half of the atoms of a radioactive material to disintegrate or undergo radioactive decay.
Tropical forests, including evergreen rainforests, cloud forests, seasonal deciduous forests and mangrove forests, have the highest biodiversity of all terrestrial biomes. Tropical rainforests, in particular, cover less than 7 percent of the Earth’s surface but harbor an estimated half of all existing plant and animal species. A small plot can yield hundreds of tree species – as many as all North American temperate and boreal forests combined -- and one reserve in Peru has more than 1,200 different butterflies. Dry tropical forests contain some of the same species as rainforests but fewer species overall. Among the major temperate forest types (temperate coniferous, rainforest, deciduous and mixed forests), temperate deciduous and mixed forests -- which include both deciduous and coniferous species -- have the highest biodiversity. Some temperate coniferous forests consist of only a few tree species, but the chatter and songs of great varieties of birds often fill their borders.( from the science book online )
