Plasmodesmata-Plasmodesmata are small tubes that connect plant cells to each other, providing living bridges between cells. Plasma Membrane-All living cells have a plasma membrane that encloses their contents. In prokaryotes and plants, the membrane is the inner layer of protection surrounded by a rigid cell wall.
Great blue herons and other aquatic birds eat crayfish. This includes surface feeding birds such as gadfly petrels, frigatebirds, gulls and fulmars. Crayfish escape from their predators by using a tail flip response. This rapid flip of their tails allows them to speed through the water away from danger.
What do sunbirds eat? by BESG | posted in: Feeding-invertebrates, Feeding-plants, Sunbirds | 29. Sunbirds are a group of small Old World passerine birds that feed mainly on nectar but also take insects and small fruits (left top). When feeding their young, insects are the main diet. Sunbirds are considered the jewels of the Old World tropics. Many species, especially the males, possess glittering iridescent colours. In morphology and nectar feeding behaviour, they remind one of the hummingbirds of the neotropics. In both groups, the females are plain. But sunbirds and hummingbirds are definitely not related. Sunbirds are omnivorous, feeding primarily on nectar and insects.
