Answer:
3.1 skeleton is an internal or external framework of bone, cartilage, or other rigid material supporting or containing the body of an animal or plant.
3.2 heterotroph is an organism that eats other plants or animals for energy and nutrients. ... Examples include plants, algae, and some types of bacteria. Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs.
3.3 An organism that manufactures its own food from inorganic substances using light for energy. Green plants, certain algae, and photosynthetic bacteria are phototrophs.
3.4 Non luminous bodies are those bodies which do not emit light of their own, but are visible when light falls on those. Planets do not have their own light. They reflect light from the Sun and are thus visible. Stars and the Sun are luminous objects and they emit light. Examples of non-luminous objects are the moon, plants, and spoons.
3.5 A medium which has the property of transmitting rays of light in such a way that the human eye may see through the medium distinctly. A medium transparent to other regions of the electromagnetic spectrum, such as x-rays and microwaves.
3.6 A compass is a magnetometer used for navigation and orientation that shows direction relative to the geographic cardinal directions
3.7 The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is one of the two points where Earth's axis of rotation intersects its surface. It is the southernmost point on the surface of Earth and lies on the opposite side of Earth from the North Pole
3.8 Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation. Dew and fog can also be collected with nets or other tools. Rainwater harvesting differs from stormwater harvesting as the runoff is collected from roofs, rather than creeks, drains, roads, or any other land surfaces.Its uses include watering gardens, livestock,irrigation, domestic use with proper treatment, and domestic heating. The harvested water can also be committed to longer-term storage or groundwater recharge.
