There are many plants that have special structure to protect themselves from human and other animals. A good example is the poisonous ivy which produces urushiol and roses that have thorns for protection.
Looking at the structure of plants, the bigger the structure of the plant the better chances it has to survive longer, but plants also guard themselves with different defense mechanisms such as poison, spines, prickles and thorns.
yes
Plants are independent , human being depend on plants and animals.
One thing that is being done to protect the blue bird of paradise from extinction is rebuilding their habitat by planting new plants and trees. There are also many reserves built to give the birds and other animals a safe place to live.
deep roots?
some animals being endangered in the coral reef are special types of squid
Plants are not animals, they make their own food through the process of photosynthesis. Animals, on the other hand, rely on consuming other plants or animals for their own well being and health. Plants, by definition, are detritivores.
They protect the plant from being eaten by certain animals.
when animals are endangerd zoologyists take them and protect them in a speacial zoo and get the animals to reproduce and when they become unendangered they release them back into the while but keep a close eye
thistles stop plants from being eaten by grazing animals, which the plants dont "want".
Humans do - being omnivores.
Thorns, spines
All animals try to protect themselves in one way or another. It is part of being alive.
