Animals, who must use some of their energy for mobility, obviously need more energy to survive than plants. These organs require energy for maintenance and performance. It is more energy-expensive to be an animal than a plant. Growth Growing takes energy. If there is not enough energy for growth during a growing period, the living thing may be stunted.
Plants grow when temperatures are favorable.
In spring, rising temperatures and longer days allow plants to grow and use additional energy for flowering. In summer, when days are at their longest and the most light energy is available, plants continue to grow and use more energy to make their seeds. In autumn, as days grow shorter, plants store any excess energy in their tissues, or in bulbs, or underground tubers, and prepare to spend the winter being dormant. They shed their leaves, so that only slender branches are exposed to winter storms and heavy snow. Plants retain the power to grow additional limbs, stalks, and leaves until the waning of their lives.
