Secondary succession is the ecological succession that occurs after the initial succession has been disrupted and some plants and animals still exist. It is usually faster than primary succession
The answer is conduction. This is a form of heat transfer due to temperature difference, through direct contact with objects that are touching, in which the hotter object passes heat to the cooler objects by molecular collisions. Convection is another form of heat transfer in which heat travels through fluids while radiation through empty spaces.
The migratory orientation of the Indigo Buntings can be primarily attributed to the species' accurate reading from their exposure to sky patterns and stars in the night sky which makes them move southward compared to other species. The study was pioneered by prominent zoologist Emlen.
According to the opponent process theory cells that are stimulated by exposure to yellow; light are inhibited by exposure to blue light.
