Honeybees were brought to North America from Europe in the 1600s. They produce honey and pollinate crops. In recent years honeybee populations across the continent have declined by as much as 70 percent. Their loss could effect fruits and vegetables such as apples‚ broccoli‚ strawberries‚ nuts‚ asparagus‚ blueberries and cucumbers. Honeybees pollinate $14 billion worth of seeds and crops in the US every year. Therefore‚ if honeybees disappear‚ they could take most of our insect pollinated plants

In biology and ecology‚ extinction is the end of an organism or of a group of organisms (taxon)‚ normally a species. The moment of extinction is generally considered to be the death of the last individual of the species‚ although the capacity to breed and recover may have been lost before this point. Because a species’ potential range may be very large‚ determining this moment is difficult‚ and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa‚ where a species

Some of these characteristics may be deemed bizarre. Plants have come a long way since their shift to terrestrial habitats from aquatic habitats millions of years ago. From the development of the cuticle to prevent water loss to the evolution of vascular tissues to provide for efficient internal transportation‚ all evolutionary changes took

individual flowers are tightly packed onto a fleshy core. The spathe which is a large bract partially enclosing the spadix surrounds the latter and the space formed between these two structures serves as a resting place and shelter for insect pollinators. Another characteristic that can be seen in Aroids‚ particularly in C. esculenta is protogyny. This process involves the female flowers becoming fertile and receptive before the male flowers to help ensure successful cross pollination. The leaves
