The Cambrian Period marks an important point in the history of life on Earth; it is the time when most of the major groups of animals first appear in the fossil record. This event is sometimes called the "Cambrian Explosion," because of the relatively short time over which this diversity of forms appears
Answer:
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms. It keeps the "balance" in nature.
Explanation:
<span>I usually think of biology first, and then physics. I trust those types of science a whole lot more than social sciences. I don't think of it like most non-sciency people do (like with diet pills and perfume). I think of it like using the actual scientific method, doing the same thing over and again expecting different results, taking the objective (or subjective, when that applies) results and forming a logical conclusion and not one that fits your hypothesis/agenda. Kind of like those kids that every high school has (on TV shows, they're the ones that are doing something with robotics all the time) that are nerdy, science geeks always running experiments and seeing what happens. </span>
