Question

An organisms that can make its own found
The percentage of energy is passed on to each tropic level......
The percentage of nitrogen in the atmosphere​

Answer 1

Answer:

Autotrophs (producers) synthesize their own energy, creating organic materials that are utilized as fuel by heterotrophs (consumers).

Food webs illustrate how energy flows through ecosystems, including how efficiently organisms acquire and use it.

Autotrophs, producers in food webs, can be photosynthetic or chemosynthetic.

Photoautotrophs use light energy to synthesize their own food, while chemoautotrophs use inorganic molecules.

Chemoautotrophs are usually bacteria that live in ecosystems where sunlight is unavailable.

Heterotrophs cannot synthesize their own energy, but must obtain it from autotrophs or other heterotrophs; they act as consumers in food webs.

Explanation:

photoautotroph: an organism that can synthesize its own food by using light as a source of energy

chemoautotroph: a simple organism, such as a protozoan, that derives its energy from chemical processes rather than photosynthesis

heterotroph: an organism that requires an external supply of energy in the form of food, as it cannot synthesize its own

Answer 2

Explanation:

Notice that the energy decreases with each increase in trophic level. Because all organisms need to use some of this energy for their own.
