5.) 10 PERCENT

Answer:

1.)the sun

The vast majority of energy in food webs originates from the sun. Energy is not recycled in ecosystems and each ecosystem requires a continuous input of energy to sustain it. There is some energy transformed at each level of the food chain or food web in an ecosysteM

2.)A food chain is a series of steps in which organisms transfer energy by eating and being eaten. Producers, such as floating algae called phytoplankton, are at the base of every food chain. A food web is a network of all the food chains in an ecosystem. Food webs are very complex.

3.)the sun

Most energy comes from the sun, either directly or indirectly: Most life forms on earth get their energy from the sun. Plants use photosynthesis to capture sunlight, and herbivores eat those plants to obtain energy.

4.)When energy is transformed from one form to another, or moved from one place to another, or from one system to another there is energy loss. This means that when energy is converted to a different form, some of the input energy is turned into a highly disordered form of energy, like heat.

Explanation:

5.)0.1%

If 100 percent of the energy available at the first trophic level, what percentage of the total energy available at the highest trophic level? 0.1% energy will be available at the highest trophic level.
