Question

How autotrophs respond to various external factors?

Answer 1

Answer:

Autotrophs are organisms that produce new biomass from inorganic resources (carbon dioxide and mineral nutrients), using either light energy (photoautotrophs) or energy from reduced molecules in the environment (chemoautotrophs). The vast majority of energy in aboveground and marine habitats enters via photosynthesis in photoautotrophs. Chemoautotrophs form a large hidden biomass in the upper Earth’s crust where they use geological sources of energy to assimilate carbon and mineral nutrients.

Answer 2

Autotrophs response to various external factors:

• Auto trophic organism can produce its own energy by using light, carbon dioxide, water or other chemicals. Because they produce own food, they are called producers.

• Most of the majority of energy in above ground and marine habitats enters through photosynthesis in photoautotrophs and in Chemoautotrophs form a huge hidden biomass in upper Earth’s crust where we use geological sources of energy to assimilate carbon and  othervmineral nutrients.

• Factors affecting autotrophs are: air pollutants, nutrients, water, oxygen , temperature, duration of light availability.
