The first is the workers‚ who forage for food‚ build and protect the hive‚ clean‚ circulate air by beating their wings‚ and perform many other societal functions. The second type of honeybee is the female queen bee. Her job is to lay the eggs of the next generation of bees. The last type of

maturity. Another example of a postzygotic barrier is ‘behavioral sterility‚’ which is a hybrid that reaches sexual maturity but cannot produce appropriate mating behavior. An example of this would be plants that grow flowers that cannot attract pollinators. The last type of postzygotic gene barrier is ‘hybrid sterility’ that means the hybrids fail to produce efficient gametes‚ such as a mule. The prezygotic gene barriers are anything that prevents mating and fertilization. One example of a prezygotic

Changes in the local environment resulting from habitat fragmentation and habitat degradation can have disruptive effects on plant-pollinator interactions ultimately hindering reproduction and limiting diversity. The alteration of plant-pollinator relationships contributes to the loss of diversity due to the inability of agricultural production to grow and flourish from a reduction in pollen quality and quantity (Chi & Molano-Flores 2015)

unique and incredible species. They are unique because they are social insects and there very interesting to study. They are fascinating creatures and great for models of natural pheromone. Bees have many features that set them apart from other pollinators. And how they act and how they respond to things are such fascination things to see. Albert Einstein once said that “If the honeybee goes extinct‚ we have four more years on Earth.” Bees play a major role in

The 6th Major Extinction An Extinction is when tens of thousands are in danger of dying out completely. A Mass Extinction is when multiple different kind of species die out completely. Human activities do the most damage to animal habitats. Human activities include Illegal hunting‚ pollution from factories‚ and moving in of an invasive species which could mess up the whole ecosystem. Another example of human activities was back in the early 1800s‚ there were about 2 billion Passenger Pigeons
