Question

HELP ME PLEASE I BEG

Answer 1

Answer:

Explanation:

energy flows from the Sun to producers and then to consumers. The path is linear as the energy present in one step is transferred to the next. You can find specific examples of this pathway in an ecosystem. Energy may be lost in living systems as it flows through them.

Photosynthesis is  the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Answer 2

Answer:

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.

Hope this helps you.
