Many animals use adaptive structures to get food like the animal may wait until the other animal is dead like a vulture.
They evolved to fill the niches found on land.
adaptive radiation
A structural adaptation of plants is that bark helps limit the moisture evaporated from atree trunk.
they prevent too much loss of water
no they had no new adaptations to the environment as their body structures were adapted to the environment

in dogs there are many adapticve features: the fact that they can coordinate themselves (hunt in packs) this is useful because there is a greateer chance of sucess when more animals are involved. the dogs acute sense of smell helps it find food, potential mates and potential rivals. a dogs strong jaw muscles necessary when hunting in fish the most obvious would be the stremlined structure which makes it easier by reducing friction and water resistance. the most useful would be gills allowing the fish to breath. the fact that some fish swim in schools. it decreases the chance of being selected by predetors as food
Plants with protective structores
Thorns, spines (such as those on a cactus), and prickles are examples of protective structures of plants.
