Which of the following conduct the most pollination for angiosperms?
squirrels
butterflies
birds
bees

In this item, we are given with four insects and animals: (1) squirrels, (2) butterflies, (3) birds, and (4) bees. we are to determine which among them conduct the most pollination for angiosperms. The answer to this item is bees. That is the fourth among the choices.

Bees are the most responsible organsism for pollination in angiosperms. They take nectar from the flowers of angiosperms,and bees take the pollen.When bee visits other plan, they may leave the pollen there and cause pollination. This is a mutual relationship.

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.

Carbon monoxide is the answer: )
