As the term ecological footprint means the impact of one's foot over the ecological systems. Its also seen as the foot of consumption, It is the ability of the earth or the ecological system to produce the demanded stuff that is required for the existence and survival of the organisms, that compete for biological space.
The term in short also is used to define biocapacity. This Also states the biological component to absorb the carbon content created by the organism The biological capacity in polar decreases and increases in trophic levels.
Similarly, the oceanic productive and biological carrying capacity is impacted by this demand cycle. Related to the food chain and food web.
Thus it's essential that this productivity is maintained and is needed as an energy source to absorb and recycle the wastes and pollution produced by continuous resource use.
The primary productivity is measured by autotrophic level and secondary productivity is measured by heterotrophic level.
1. The phases of the moon are caused due to the earth's rotations on its axis and the moon rotation around the earth in its elliptical orbit. Certain phases f the moon are caused due to the sun and moon positions about that of the earth on the full moon, new moon and half-moon days. Most of the time we see the same face of the moon.
2. Planet venus show similar properties to that of the moon as both the moon and venus have are made up of same gem material like earth and being a terrestrial planet the venus and both revolve on in the same opposite direction of the earth thus earth sees the same phase of the venus as in the moon.
3. A solar eclipse occurs when the moon blocks the rays id sun and a ring-shaped formations take place when the earth comes in way of the or between the moon and sun the shadows of the earth fall on the moon and hence lunar eclipse takes place.
4. The north star also called the Polaris star seems to change its position for the southern hemisphere, but as for the northern hemisphere, it remains the same as being the north star the equatorial belt the star remains or shows the same side. Due to the rotation and axial tilt of the earth.
5. The cause of sunrise and sunset is mainly due to the sun and the earth's movement around the horizon in the opposite direction and there is 12 hours gap.
