Answer 1

Explanation:

dead and decaying plant and animal

Answer 2

There are only two types of autotrophs. Photoautotrophs and Chemoautotrophs are the two autotrophs.

Photoautotrophs : Photoautotrophs are organisms who get the energy to make organic materials from sunlight. Photoautotrophs include all plants, green algaes, and bacteria which perform photosynthesis.

Chemoautotrophs : Chemoautotrophs are organisms that obtain energy from inorganic chemical processes. Today, chemoautotrophs are most commonly found in deep water environments which receive no sunlight. Many need to live around deep sea volcanic vents, which produce enough heat to allow metabolism to occur at a high rate.

Examples of Autotrophs.

1. Green Algae

2. Iron Bacteria ( Acidithiobacillus ferrooxidans )

3. Plants
