Why are bees considered a keystone species?
A
The honey they make supports the bear population
B
They pollinate flowers that produce fruit which supports the ecosystem
C
They sting when threatened
D
They live in hives
Explanation: 

Detailed explanation-1: -Nearly ninety per cent of wild flowering plants need pollinators like bees to transfer pollen for successful sexual reproduction. In turn, these plants are critical in the functioning of ecosystems. They provide food, form habitats and provide a wide range of other resources for many animal species.

Detailed explanation-2: -Native bees are the most predominant pollinators of flowering plants in nature, thus contributing a vital service to the ecosystem. Because of this important role, bees are referred to as “keystone species”.

Detailed explanation-3: -According to bee experts at the Food and Agriculture Organization (FAO) of the United Nations, a third of the world’s food production depends on bees. When animals and insects pick up the pollen of flowers and spread it, they allow plants, including many food crops, to reproduce.

Detailed explanation-4: -They serve important roles not only as pollinators but also as creators of honey, propolis, pollen, habitats for other species, and as food for larger species that serve their own important roles in an ecosystem’s web.

Detailed explanation-5: -Pollination not only results in the production of fruits, seeds, and subsequent plants that are produced from agriculture and for the purpose of feeding livestock, but maintains and increases diversity within and between native species of plants.
