Answer:
The correct option is C.
Explanation:
There are three modes of heat conduction, these are conduction, convection and radiation. Heat transfer by conduction usually involves the movement of heat through solid substances. For instance, in the scenario given in this question, the warm surface is the solid substance through which heat is passed to the insects' bodies. Thus, conduction requires direct contact.
Heat transfer by convection method usually involves the movement of heat through liquids or gases while radiation can occur in vacuum.
Answer:
Polar bears consume ringed seals (which are tertiary consumers) as well as fish like trout, salmon, and cod (which are secondary consumers).

Answer:
Nitrate is the form of nitrogen most used by plants for growth and development. Nitrate is the form that can most easily be lost to groundwater. Ammonium taken in by plants is used directly in proteins. This form is not lost as easily from the soil
The two main processes by which plant cells absorb, release, and use
energy are photosynthesis and respiration. The
process of photosynthesis is present in the chloroplasts of a pant cell.
Photosynthesis uses the sun’s rays in the form of electromagnetic energy to
convert it into chemical energy to be used for the plants. It needs proteins
that are present in the plants to perform a series of necessary conversions.
Moreover, the energy from the sun is the main catalyst to convert the
carbohydrates in the plant into simpler sugars. And then a series of complex
reaction takes place that their end product is oxygen. The oxygen produced is
the cellular respiration.
