Answer:
Explanation:
Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature. Heat energy is another name for thermal energy. Kinetic energy is the energy of a moving object. As thermal energy comes from moving particles, it is a form of kinetic energy.
 
        
                    
             
        
        
        
<span>Heterotrophs, organisms that must get energy from food indirectly from sunlight or inorganic substances, go through the process of cellular respiration to get the energy needed.</span>
        
             
        
        
        
I think that correct answers are: 
<span>Some of them lose their leaves in winter. (i.e. <span><em>Larix</em></span>)</span>
<span>They include the tallest plants (i.e<em>.Sequoia)
</em>I don't think they are the oldest type of seed plants, since in the past the classes like progymnosperms and seed ferns existed prior to the gymnosperms. But question isn't absolutely clear to me and I can't be 100% sure. 
All of the gymnosperms have seeds unless human grows some seedless variant.
Gymnosperms don't have flowers like angiosperms do, but some people think that cone is kind of flower. 
Male cones produce pollen, not female.
Hope I helped :)
