EVERYDAY SCIENCE

Detailed explanation-1: -Autotrophs are organisms that capture energy from nonliving sources and transfer that energy into the living part of the ecosystem. They are also able to make their own food. Most autotrophs use the energy in sunlight to make food in the process of photosynthesis.

Detailed explanation-2: -Autotrophs are organisms that get their energy from nonliving resources, meaning they make their own food. These organisms are also called Producers.

Detailed explanation-3: -Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis. An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.

Detailed explanation-4: -Chemosynthetic bacteria are organisms that use inorganic molecules as an energy source to produce food. There are two types of this bacteria: chemoautotrophs and chemoheterotrophs.

Detailed explanation-5: -3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.
