Tundra ecosystem is cold and sunlight is short. Plants need sunglight and warmth in order to grow, thus plants in tundra are shorter and cloers to the ground since the ground is warmer than the air
For instance, due to the normal aging process, muscle properties decline about 30–50% between the ages of 40 and 80 years old; this decline may result in reduced range of motion (ROM), reduced muscle strength, and diminished plantar tactile sensation leading to alteration in plantar loading responses3).
Some <u>birds</u> are both primary consumers and secondary consumers.
<u>Explanation:</u>
Primary consumers are the class of animals that are feeding upon the producers as their primary food. Secondary consumers are the class of animals that are feeding upon a primary consumer to feed themselves.
